Fixing the Linux black screen of death on machines with Intel HD video
-
11th June 2013
-

When installing RedHat, Fedora, Debian and Ubuntu on some machines, -the screen just turn black when Linux boot, either during installation -or on first boot from the hard disk. I've seen it once in a while the -last few years, but only recently understood the cause. I've seen it -on HP laptops, and on my latest acquaintance the Packard Bell laptop. -The reason seem to be in the wiring of some laptops. The system to -control the screen background light is inverted, so when Linux try to -turn the brightness fully on, it end up turning it off instead. I do -not know which Linux drivers are affected, but this post is about the -i915 driver used by the -Packard Bell -EasyNote LV, Thinkpad X40 and many other laptops.

- -

The problem can be worked around two ways. Either by adding -i915.invert_brightness=1 as a kernel option, or by adding a file in -/etc/modprobe.d/ to tell modprobe to add the invert_brightness=1 -option when it load the i915 kernel module. On Debian and Ubuntu, it -can be done by running these commands as root:

- -
-echo options i915 invert_brightness=1 | tee /etc/modprobe.d/i915.conf
-update-initramfs -u -k all
-
- -

Since March 2012 there is -a -mechanism in the Linux kernel to tell the i915 driver which -hardware have this problem, and get the driver to invert the -brightness setting automatically. To use it, one need to add a row in -the -intel_quirks array in the driver source -drivers/gpu/drm/i915/intel_display.c (look for "static -struct intel_quirk intel_quirks"), specifying the PCI device -number (vendor number 8086 is assumed) and subdevice vendor and device -number.

- -

My Packard Bell EasyNote LV got this output from lspci --vvnn for the video card in question:

- -

-00:02.0 VGA compatible controller [0300]: Intel Corporation \
-    3rd Gen Core processor Graphics Controller [8086:0156] \
-    (rev 09) (prog-if 00 [VGA controller])
- Subsystem: Acer Incorporated [ALI] Device [1025:0688]
- Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- \
-    ParErr- Stepping- SE RR- FastB2B- DisINTx+
- Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort- \
-    SERR-  [disabled]
- Capabilities: 
- Kernel driver in use: i915
-

- -

The resulting intel_quirks entry would then look like this:

- -

-struct intel_quirk intel_quirks[] = {
-       ...
-        /* Packard Bell EasyNote LV11HC needs invert brightness quirk */
-	{ 0x0156, 0x1025, 0x0688, quirk_invert_brightness },
-       ...
-}
-

- -

According to the kernel module instructions (as seen using -modinfo i915), information about hardware needing the -invert_brightness flag should be sent to the -dri-devel -(at) lists.freedesktop.org mailing list to reach the kernel -developers. But my email about the laptop sent 2013-06-03 have not -yet shown up in -the -web archive for the mailing list, so I suspect they do not accept -emails from non-subscribers. Because of this, I sent my patch also to -the Debian bug tracking system instead as -BTS report #710938, to make -sure the patch is not lost.

- -

Unfortunately, it is not enough to fix the kernel to get Laptops -with this problem working properly with Linux. If you use Gnome, your -worries should be over at this point. But if you use KDE, there is -something in KDE ignoring the invert_brightness setting and turning on -the screen during login. I've reported it to Debian as -BTS report #711237, and -have no idea yet how to figure out exactly what subsystem is doing -this. Perhaps you can help? Perhaps you know what the Gnome -developers did to handle this, and this can give a clue to the KDE -developers? Or you know where in KDE the screen brightness is changed -during login? If so, please update the BTS report (or get in touch if -you do not know how to update BTS).

Via Debian +Project News for 2013-10-14 I came across the Outreach Program for +Women program which is a Google Summer of Code like initiative to get +more women involved in free software. One debian sponsor has offered +to match any donation done to Debian +earmarked for this initiative. I donated a few minutes ago, and +hope you will to. :)

+ +

And the Electronic Frontier Foundation just announced plans to +create video +documentaries about the excessive spying on every Internet user that +take place these days, and their need to fund the work. I've already +donated. Are you next?

+ +

For my Norwegian audience, the organisation Studentenes og +Akademikernes Internasjonale Hjelpefond is collecting signatures for a +statement under the heading +Bloggers United for Open +Access for those of us asking for more focus on open access in the +Norwegian government. So far 499 signatures. I hope you will sign it +too.

Wireless mesh networks are self organising and self healing +networks that can be used to connect computers across small and large +areas, depending on the radio technology used. Normal wifi equipment +can be used to create home made radio networks, and there are several +successful examples like +Freifunk and +Athens Wireless Metropolitan Network +(see +wikipedia +for a large list) around the globe. To give you an idea how it +work, check out the nice overview of the Kiel Freifunk community which +can be seen from their +dynamically +updated node graph and map, where one can see how the mesh nodes +automatically handle routing and recover from nodes disappearing. +There is also a small community mesh network group in Oslo, Norway, +and that is the main topic of this blog post.

+ +

I've wanted to check out mesh networks for a while now, and hoped +to do it as part of my involvement with the NUUG member organisation community, and +my recent involvement in +the Freedombox project +finally lead me to give mesh networks some priority, as I suspect a +Freedombox should use mesh networks to connect neighbours and family +when possible, given that most communication between people are +between those nearby (as shown for example by research on Facebook +communication patterns). It also allow people to communicate without +any central hub to tap into for those that want to listen in on the +private communication of citizens, which have become more and more +important over the years.

+ +

So far I have only been able to find one group of people in Oslo +working on community mesh networks, over at the hack space +Hackeriet at Husmania. They seem to +have started with some Freifunk based effort using OLSR, called +the Oslo +Freifunk project, but that effort is now dead and the people +behind it have moved on to a batman-adv based system called +meshfx. Unfortunately the wiki +site for the Oslo Freifunk project is no longer possible to update to +reflect this fact, so the old project page can't be updated to point to +the new project. A while back, the people at Hackeriet invited people +from the Freifunk community to Oslo to talk about mesh networks. I +came across this video where Hans Jørgen Lysglimt interview the +speakers about this talk (from +youtube):

+ +

+ +

I mentioned OLSR and batman-adv, which are mesh routing protocols. +There are heaps of different protocols, and I am still struggling to +figure out which one would be "best" for some definitions of best, but +given that the community mesh group in Oslo is so small, I believe it +is best to hook up with the existing one instead of trying to create a +completely different setup, and thus I have decided to focus on +batman-adv for now. It sure help me to know that the very cool +Serval project in Australia +is using batman-adv as their meshing technology when it create a self +organizing and self healing telephony system for disaster areas and +less industrialized communities. Check out this cool video presenting +that project (from +youtube):

+ +

+ +

According to the wikipedia page on +Wireless +mesh network there are around 70 competing schemes for routing +packets across mesh networks, and OLSR, B.A.T.M.A.N. and +B.A.T.M.A.N. advanced are protocols used by several free software +based community mesh networks.

+ +

The batman-adv protocol is a bit special, as it provide layer 2 +(as in ethernet ) routing, allowing ipv4 and ipv6 to work on the same +network. One way to think about it is that it provide a mesh based +vlan you can bridge to or handle like any other vlan connected to your +computer. The required drivers are already in the Linux kernel at +least since Debian Wheezy, and it is fairly easy to set up. A +good +introduction is available from the Open Mesh project. These are +the key settings needed to join the Oslo meshfx network:

+ +

+ + + + + +
SettingValue
Protocol / kernel modulebatman-adv
ESSIDmeshfx@hackeriet
Channel / Frequency11 / 2462
Cell ID02:BA:00:00:00:01

+ +

The reason for setting ad-hoc wifi Cell ID is to work around bugs +in firmware used in wifi card and wifi drivers. (See a nice post from +VillageTelco about +"Information +about cell-id splitting, stuck beacons, and failed IBSS merges! +for details.) When these settings are activated and you have some +other mesh node nearby, your computer will be connected to the mesh +network and can communicate with any mesh node that is connected to +any of the nodes in your network of nodes. :)

+ +

My initial plan was to reuse my old Linksys WRT54GL as a mesh node, +but that seem to be very hard, as I have not been able to locate a +firmware supporting batman-adv. If anyone know how to use that old +wifi access point with batman-adv these days, please let me know.

+ +

If you find this project interesting and want to join, please join +us on IRC, either channel +#oslohackerspace +or #nuug on +irc.freenode.net.

+ +

While investigating mesh networks in Oslo, I came across an old +research paper from the university of Stavanger and Telenor Research +and Innovation called +The +reliability of wireless backhaul mesh networks and elsewhere +learned that Telenor have been experimenting with mesh networks at +Grünerløkka in Oslo. So mesh networks are also interesting for +commercial companies, even though Telenor discovered that it was hard +to figure out a good business plan for mesh networking and as far as I +know have closed down the experiment. Perhaps Telenor or others would +be interested in a cooperation?

+ +

Update 2013-10-12: I was just +told +by the Serval project developers that they no longer use +batman-adv (but are compatible with it), but their own crypto based +mesh system.

The result is 11 minutes long, +and show some user applications (seem to be rather randomly picked). +Missed a few of my favorites like celestia, planets and chromium +showing the Zygote Body 3D model +of the human body, but I guess he did not know about those or find +other programs more interesting. :) And the video do not show the +advantages I believe is one of the most valuable featuers in Debian +Edu, its central school server making it possible to run hundreds of +computers without hard drives by installing one central +LTSP server.

    Here is a call for help from the Debian Edu / Skolelinux project. -We have two problems blocking the release of the Wheezy version we -hope to get released soon. The two problems require some with PHP -skills, and we seem to lack anyone with both time and PHP skills in -the project: +

    +
    10th September 2013
    +

    I was introduced to the +Freedombox project +in 2010, when Eben Moglen presented his vision about serving the need +of non-technical people to keep their personal information private and +within the legal protection of their own homes. The idea is to give +people back the power over their network and machines, and return +Internet back to its intended peer-to-peer architecture. Instead of +depending on a central service, the Freedombox will give everyone +control over their own basic infrastructure.

    + +

    I've intended to join the effort since then, but other tasks have +taken priority. But this summers nasty news about the misuse of trust +and privilege exercised by the "western" intelligence gathering +communities increased my eagerness to contribute to a point where I +actually started working on the project a while back.

    + +

    The initial +Debian initiative based on the vision from Eben Moglen, is to +create a simple and cheap Debian based appliance that anyone can hook +up in their home and get access to secure and private services and +communication. The initial deployment platform have been the +Dreamplug, +which is a piece of hardware I do not own. So to be able to test what +the current Freedombox setup look like, I had to come up with a way to install +it on some hardware I do have access to. I have rewritten the +freedom-maker +image build framework to use .deb packages instead of only copying +setup into the boot images, and thanks to this rewrite I am able to +set up any machine supported by Debian Wheezy as a Freedombox, using +the previously mentioned deb (and a few support debs for packages +missing in Debian).

    + +

    The current Freedombox setup consist of a set of bootstrapping +scripts +(freedombox-setup), +and a administrative web interface +(plinth + exmachina + +withsqlite), as well as a privacy enhancing proxy based on +privoxy +(freedombox-privoxy). There is also a web/javascript based XMPP +client (jwchat) +trying (unsuccessfully so far) to talk to the XMPP server +(ejabberd). The +web interface is pluggable, and the goal is to use it to enable OpenID +services, mesh network connectivity, use of TOR, etc, etc. Not much of +this is really working yet, see +the +project TODO for links to GIT repositories. Most of the code is +on github at the moment. The HTTP proxy is operational out of the +box, and the admin web interface can be used to add/remove plinth +users. I've not been able to do anything else with it so far, but +know there are several branches spread around github and other places +with lots of half baked features.

    + +

    Anyway, if you want to have a look at the current state, the +following recipes should work to give you a test machine to poke +at.

    + +

    1. It is impossible to log into the slbackup web interface - (slbackup-php) using the root user and password. This is - BTS report #700257. - This used to work, but stopped working some time since Squeeze. - Perhaps some obsolete PHP feature was used?
    2. +
    3. Fetch normal Debian Wheezy installation ISO.
    4. +
    5. Boot from it, either as CD or USB stick.
    6. +
    7. Press [tab] on the boot prompt and add this as a boot argument +to the Debian installer:

      +

      url=http://www.reinholdtsen.name/freedombox/preseed-wheezy.dat
    8. + +
    9. Answer the few language/region/password questions and pick disk to +install on.
    10. -
    11. It is not possible to "mass import" user lists in Gosa, neither - using ldif nor using CSV files. The feature was disabled after a - major rewrite of Gosa, and need to be ported to the new system. - This is BTS report - #698840.
    12. +
    13. When the installation is finished and the machine have rebooted a +few times, your Freedombox is ready for testing.

    Raspberry Pi Raspbian

    + +
      + +
    1. Fetch a Raspbian SD card image, create SD card.
    2. +
    3. Boot from SD card, extend file system to fill the card completely.
    4. +
    5. Log in and add this to /etc/sources.list:

      +
      +deb http://www.reinholdtsen.name/freedombox wheezy main
      +
    6. +
    7. Run this as root:

      +
      +wget -O - http://www.reinholdtsen.name/freedombox/BE1A583D.asc | \
      +   apt-key add -
      +apt-get update
      +apt-get install freedombox-setup
      +/usr/lib/freedombox/setup
      +
    8. +
    9. Reboot into your freshly created Freedombox.
    10. + +
    + +

    You can test it on other architectures too, but because the +freedombox-privoxy package is binary, it will only work as intended on +the architectures where I have had time to build the binary and put it +in my APT repository. But do not let this stop you. It is only a +short "apt-get source -b freedombox-privoxy" away. :)

    + +

    Note that by default Freedombox is a DHCP server on the +192.168.1.0/24 subnet, so if this is your subnet be careful and turn +off the DHCP server by running "update-rc.d isc-dhcp-server +disable" as root.

    + +

    Please let me know if this works for you, or if you have any +problems. We gather on the IRC channel +#freedombox on +irc.debian.org and the +project +mailing list.

    Once you get your freedombox operational, you can visit +http://your-host-name:8001/ to see the state of the plint +welcome screen (dead end - do not be surprised if you are unable to +get past it), and next visit http://your-host-name:8001/help/ +to look at the rest of plinth.

    It has been a while since my last English -Debian Edu and Skolelinux -interview last November. But the developers and translators are still -pulling along to get the Wheezy based release out the door, and this -time I managed to get an interview from one of the French translators -in the project, Cédric Boutillier.

    - -

    Who are you, and how do you spend your days?

    - -

    I am 34 year old. I live near Paris, France. I am an assistant -professor in probability theory. I spend my daytime teaching -mathematics at the university and doing fundamental research in -probability in connexion with combinatorics and statistical physics.

    - -

    I have been involved in the Debian project for a couple of years -and became Debian Developer a few months ago. I am working on Ruby -packaging, publicity and translation.

    - -

    How did you get in contact with the Skolelinux / Debian Edu -project?

    - -

    I came to the Debian Edu project after a call for translation of -the -Debian Edu manual for the release of Debian Edu Squeeze. Since -then, I have been working on updating the French translation of the -manual. - -

    I had the opportunity to make an installation of Debian Edu in a -virtual machine when I was preparing localised version of some screen -shots for the manual. I was amazed to see it worked out of the box and -how comprehensive the list of software installed by default was.

    - -

    What amazed me was the complete network infrastructure directly -ready to use, which can and the nice administration interface provided -by GOsa². What pleased -me also was the fact that among the software installed by default, -there were many "traditional" educative software to learn languages, -to count, to program... but also software to develop creativity and -artistic skills with music (Ardour, -Audacity) and -movies/animation (I was especially thinking of -Stopmotion).

    - -

    I am following the development of Debian Edu and am hanging out on -#debian-edu. -Unfortunately, I don't much time to get more involved in this -beautiful project.

    - -

    What do you see as the advantages of Skolelinux / Debian -Edu?

    - -

    For me, the main advantages of Skolelinux/Debian Edu are its -community of experts and its precise documentation, as well as the -fact that it provides a solution ready to use.

    - -

    I would add also the fact that it is based on the rock solid Debian -distribution, which ensures stability and provides a huge collection -of educational free software.

    - -

    What do you see as the disadvantages of Skolelinux / Debian -Edu?

    Maybe the lack of manpower to do lobbying on the -project. Sometimes, people who need to take decisions concerning IT do -not have all the elements to evaluate properly free software -solutions.

    I 2011 raderte et stortingsflertall bestående av Høyre og +Arbeiderpartiet vekk en betydelig del av privatsfæren til det norske +folk. Det ble vedtatt at det skulle registreres og lagres i et halvt +år hvor alle som bærer på en mobiltelefon befinner seg, hvem de +snakker med og hvor lenge de snakket sammen. Det skal også +registreres hvem de sendte SMS-meldinger til, hvem en har sendt epost +til, og hvilke nett-tjenere en besøkte. Saken er kjent som +Datalagringsdirektivet +(DLD), og innebærer at alle innbyggerne og andre innenfor Norges +grenser overvåkes døgnet rundt. Det ble i praksis innført brev og +besøkskontroll av hele befolkningen. Rapporter fra de landene som +allerede har innført slik total lagring av borgernes +kommunikasjonsmønstre forteller at det ikke hjelper i +kriminalitetsbekjempelsen. Den norske prislappen blir mange hundre +millioner, uten at det ser ut til å bidra positivt til politiets +arbeide. Jeg synes flere hundre millioner i stedet burde vært brukt +på noe som kan dokumenteres å ha effekt i kriminalitetsbekjempelsen. +Se mer på +Wikipedia +og Jon Wessel-Aas.

    + +

    Hva er problemet, tenkter du kanskje? Et åpenbart problem er at +medienes kildevern i praksis blir radert ut. Den innsamlede +informasjonen gjør det mulig å finne ut hvem som har snakket med +journalister på telefon, SMS og epost, og hvem som har vært i nærheten +av journalister så sant begge bar med seg en telefon. Et annet er at +advokatvernet blir sterkt redusert, der politiet kan finne ut hvem +som har snakket med en advokat når, eller vært i møter en med advokat. +Et tredje er at svært personlig informasjon kan avledes fra hvilke +nettsteder en har besøkt. Har en besøkt hivnorge.no, +swingersnorge.com eller andre sider som kan brukes til avlede +interesser som hører til privatsfæren, vil denne informasjonen være +tilgjengelig takket være datalagringsdirektivet.

    + +

    De fleste partiene var mot, kun to partier stemte for. Høyre og +Arbeiderpartiet. Og både Høyre og Arbeiderpartiet i Oslo har +DLD-forkjempere på toppen av sine lister (har ikke sjekket de andre +fylkene). Det er dermed helt uaktuelt for meg å stemme på disse +partiene.

    The second wheezy based beta release of Debian Edu was wrapped up +today, slightly delayed because of some bugs in the initial Windows +integration fixes . This is the release announcement:

    + +

    New features for Debian Edu 7.1+edu0~b1 released 2013-08-22

    + +

    These are the release notes for Debian Edu / Skolelinux +7.1+edu0~b1, based on Debian with codename "Wheezy".

    + +

    About Debian Edu and Skolelinux

    + +

    Debian Edu, also known as +Skolelinux, is a Linux distribution based on Debian providing an +out-of-the box environment of a completely configured school +network. Immediately after installation a school server running all +services needed for a school network is set up just waiting for users +and machines being added via GOsa², a comfortable Web-UI. A netbooting +environment is prepared using PXE, so after initial installation of +the main server from CD or USB stick all other machines can be +installed via the network. The provided school server provides LDAP +database and Kerberos authentication service, centralized home +directories, DHCP server, web proxy and many other services. The +desktop contains +more +than 60 educational software packages and more are available from +the Debian archive, and schools can choose between KDE, Gnome, LXDE +and Xfce desktop environment.

    + +

    This is the sixth test release based on Debian Wheezy. Basically this +is an updated and slightly improved version compared to the Squeeze +release.

    + +

    ALERT: Alpha based installations should reinstall or downgrade the +versions of gosa and libpam-mklocaluser to the ones used in this beta +release. Both alpha and beta0 based installations should reinstall or +deal with gosa.conf manually; there are two options: (1) Keep +gosa.conf and edit this file as outlined +on +the mailing list. (2) Accept the new version of gosa.conf and +replace both contained admin password placeholders with the password +hashes found in the old one (backup copy!). In both cases every user +need to change their their password to make sure a password is set for +CIFS access to their home directory.

    Two days ago, I asked -how -I could install Linux on a Packard Bell EasyNote LV computer -preinstalled with Windows 8. I found a solution, but am horrified -with the obstacles put in the way of Linux users on a laptop with UEFI -and Windows 8.

    - -

    I never found out if the cause of my problems were the use of UEFI -secure booting or fast boot. I suspect fast boot was the problem, -causing the firmware to boot directly from HD without considering any -key presses and alternative devices, but do not know UEFI settings -enough to tell.

    - -

    There is no way to install Linux on the machine in question without -opening the box and disconnecting the hard drive! This is as far as I -can tell, the only way to get access to the firmware setup menu -without accepting the Windows 8 license agreement. I am told (and -found description on how to) that it is possible to configure the -firmware setup once booted into Windows 8. But as I believe the terms -of that agreement are completely unacceptable, accepting the license -was never an alternative. I do not enter agreements I do not intend -to follow.

    - -

    I feared I had to return the laptops and ask for a refund, and -waste many hours on this, but luckily there was a way to get it to -work. But I would not recommend it to anyone planning to run Linux on -it, and I have become sceptical to Windows 8 certified laptops. Is -this the way Linux will be forced out of the market place, by making -it close to impossible for "normal" users to install Linux without -accepting the Microsoft Windows license terms? Or at least not -without risking to loose the warranty?

    - -

    I've updated the -Linux Laptop -wiki page for Packard Bell EasyNote LV, to ensure the next person -do not have to struggle as much as I did to get Linux into the -machine.

    I've run into quite a problem the last few days. I bought three -new laptops for my parents and a few others. I bought Packard Bell -Easynote LV to run Kubuntu on and use as their home computer. But I -am completely unable to figure out how to install Linux on it. The -computer is preinstalled with Windows 8, and I suspect it uses UEFI -instead of a BIOS to boot.

    - -

    The problem is that I am unable to get it to PXE boot, and unable -to get it to boot the Linux installer from my USB stick. I have yet -to try the DVD install, and still hope it will work. when I turn on -the computer, there is no information on what buttons to press to get -the normal boot menu. I expect to get some boot menu to select PXE or -USB stick booting. When booting, it first ask for the language to -use, then for some regional settings, and finally if I will accept the -Windows 8 terms of use. As these terms are completely unacceptable to -me, I have no other choice but to turn off the computer and try again -to get it to boot the Linux installer.

    - -

    I have gathered my findings so far on a Linlap page about the -Packard Bell -EasyNote LV model. If you have any idea how to get Linux -installed on this machine, please get in touch or update that wiki -page. If I can't find a way to install Linux, I will have to return -the laptop to the seller and find another machine for my parents.

    I wonder, is this the way Linux will be forced out of the market -using UEFI and "secure boot" by making it impossible to install Linux -on new Laptops?

    En ting -Skolelinux-prosjektet har -hatt mye glede av er studentprosjekter. F.eks. er -stillbildeanimasjonssystemet -Stopmotion resultat av et studentprosjekt i Skolelinux. De siste -månedene har en ivrig student veiledet av Marius Kotsbak i -FRiSK testet hva en -kan få til med en datamaskin til NOK 400,- (antagelig 1700,- med -skjerm, tastatur og mus) når det brukes i Skolelinux. Jeg spurte han -om et intervju.

    - -

    Hvem er du, og hva driver du med til daglig?

    - -

    Jeg heter Nirosan Thiyagalingam. Jeg er 24 år og studerer -dataingeniør studiet ved Høgskolen i Sør Trøndelag. Interessen for -data har siden ung alder vært tilstede og jeg har i tillegg alltid -vært glad i å lære nye ting. Med teknologi som endres svært hurtig er -det alltid noe nytt å lære. Noe som igjen har gjort det svært -interessant å følge med på utviklingen. Jeg valgte dataingeniør -studiet grunnet ønske om å lære enda mer om programmering og utvikling -av store systemer.

    - -

    Hvordan kom du i kontakt med Skolelinux-prosjektet?

    - -

    Skolelinux prosjektet hørte jeg først om i media. Men det var først -når jeg skulle velge bacheloroppgave at jeg fattet mer interesse for -prosjektet. Et enkelt søk på nettet førte meg til skolelinux sine -hjemmesider. Informasjonen jeg fant der gjorde meg enda nysgjerrig og -jeg valgte derfor en oppgave som gikk ut på å få en -Raspberry PI. Altså en -ultra-billig datamaskin til å kjøre Debian Edu på lik linje med -vanlige datamaskiner. I løpet av prosjektet ble det gjort mye -forskning på nettet. Det var mye jeg måtte forstå rundt hvordan -operativsystemet Linux fungerte før jeg kunne angripe -problemet. Prøvde først å finne ut hvordan man kunne transformere en -vanlig installasjon av Skolelinux til Raspberry PI, men dette var -altfor vanskelig å jeg endte opp med mer spørsmål enn svar. Det ble -videre opprettet kontakt med Skolelinux utviklere på IRC der jeg fikk -diskutert hvilken retning jeg burde gå for å få til en fullverdig -løsning. Det ble bestemt at jeg skulle gå for å først installere -Raspian. Dette er et -operativsystem basert på Debian spesiallaget for Raspberry Pi sin -maskinvare. Nå som Debian var installert på datamaskinen gjenstod det -å installere de nødvendige Skolelinux pakkene for å få til et -fullverdig system. Disse pakkene ble installert manuelt i første -omgang, men ble senere installert automatisk via et script som Petter -Reinholdtsen laget. Dette scriptet er så enkel å bruke at man er i -gang med installasjonen i løpet av bare 5 minutter. Ikke nok med det, -alt skjer helt automatisk. Alt i alt er jeg veldig fornøyd med -resultatet av installasjonsprosessen. Raspberry Pi er en veldig svak -maskin og det merkes godt når man har installert Skolelinux på -den. Video og 3D-rendering fungerer utrolig dårlig, men nettsurfing og -kontorprogrammer fungerer godt. Det kan derfor konkluderes med at -datamaskinen er egnet for enkle oppgaver. - -

    Jeg syns det er viktig påpeke at dette kun er startfasen av en slik -løsning. På markedet finnes det nå maskiner som har bedre hardware enn -Raspberry Pi. Det er store muligheter for at man kan klare å -installere Skolelinux på disse også, og da forsvinner nok mest -sannsynlig ytelsesproblemene med Video og 3D rendering også.

    - -

    Det ble også prøvd med en løsning som gjorde at Raspberry Pi -fungerte som en tynnklient. Denne løsningen hadde langt bedre ytelse -med tanke på hastighet og brukeropplevelse. Men også her var video og -3D rendering dårlig. Det ble brukt en liten Linux distribusjon kalt -BerryTerminal for å få til -dette.

    - -

    Hva er fordelene med Skolelinux slik du ser det?

    Fordelen med Skolelinux er mange. At det er gratis er en stor -fordel, men at det er så mange som er med på å utvikle det og -vedlikeholde det er en enda større fordel. Allerede før jeg startet -med prosjektet så jeg mange fordeler, og når jeg nærmet meg sluttfasen -så jeg langt flere. At prosjektet skulle inneha en så høy kvalitet -hadde jeg aldri trodd. En vanlig Skolelinux installasjon har de -nødvendige programmene og funksjonen som både små og store skoler i -tillegg til organisasjoner kan klare seg med. At prosjektet tilbyr en -så komplett løsning er en kjempefordel. Installasjonen er knirkefri -og det er svært enkelt å installere og komme i gang.

    Hva er ulempene med Skolelinux slik du ser det?

    - -

    Ulempene jeg ser med prosjektet er ryddigheten av websidene. Selv -om websidene er enkle og konsise er det allikevel ikke appellerende i -like stor grad som for eksempel -Ubuntu sine sider. Deres side -tilbyr, i tillegg til godt design og presentasjon, en nettbasert -emulator av deres operativsystem. Dette er en stor fordel slik jeg ser -det. Bortsett fra dette ser jeg absolutt ingen ulemper med -Skolelinux-prosjektet.

    Hvilken fri programvare bruker du til daglig?

    - -

    Til daglig er jeg en flittig bruker av det åpne media -sentersystemet XBMC. Det enorme -samfunnet rundt dette prosjektet har gjort dette til et program som -dekker alles behov. Man kan tilpasse det akkurat slik man vil både med -tanke på utseende og funksjoner ved installere plug-ins eller -scripts.

    Hvilken strategi tror du er den rette å bruke for å få -skoler til å ta i bruk fri programvare?

    - -

    Strategien som burde brukes sett fra mine øyne er -markedsføring. Jeg er sikker på at om flere skoler fikk et lite innsyn -i hvor bra Skolelinux er så ville de ikke nølt med å gå over fra noe -annet som koster de store summer. At skolelinux til de grader tilbyr -en så komplett løsning bure komme frem. Enten via reklamekampanjer -eller ved å sende ut folk til skoler for så å la skolenettverk -ansvarlige få teste ut hvordan Skolelinux fungerer i praksis. Om det -i tillegg ble utviklet gode websider og en emulator for å la brukere -prøve operativsystemet ville nok dette ha styrket inntrykket -betraktelig.

    Debian Edu / Skolelinux is -an operating system based on Debian intended for use in schools. It -contain a turn-key solution for the computer network provided to -pupils in the primary schools. It provide both the central server, -network boot servers and desktop environments with heaps of -educational software. The project was founded almost 12 years ago, -2001-07-02. If you want to support the project, which is in need for -cash to fund developer gatherings and other project related activity, -please -donate some money. - -

    A topic that come up again and again on the Debian Edu mailing -lists and elsewhere, is the question on how to transform a Debian or -Ubuntu installation into a Debian Edu installation. It isn't very -hard, and last week I wrote a script to replicate the steps done by -the Debian Edu installer.

    - -

    The script, -debian-edu-bless -in the debian-edu-config package, will go through these six steps and -transform an existing Debian Wheezy or Ubuntu (untested) installation -into a Debian Edu Workstation:

    - -
      - -
    1. Add skolelinux related APT sources.
    2. -
    3. Create /etc/debian-edu/config with the wanted configuration.
    4. -
    5. Install debian-edu-install to load preseeding values and pull in - our configuration.
    6. -
    7. Preseed debconf database with profile setup in - /etc/debian-edu/config, and run tasksel to install packages - according to the profile specified in the config above, - overriding some of the Debian automation machinery.
    8. -
    9. Run debian-edu-cfengine-D installation to configure everything - that could not be done using preseeding.
    10. -
    11. Ask for a reboot to enable all the configuration changes.
    12. - -
    - -

    There are some steps in the Debian Edu installation that can not be -replicated like this. Disk partitioning and LVM setup, for example. -So this script just assume there is enough disk space to install all -the needed packages.

    - -

    The script was created to help a Debian Edu student working on -setting up Raspberry Pi as a -Debian Edu client, and using it he can take the existing -Raspbian installation and -transform it into a fully functioning Debian Edu Workstation (or -Roaming Workstation, or whatever :).

    - -

    The default setting in the script is to create a KDE Workstation. -If a LXDE based Roaming workstation is wanted instead, modify the -PROFILE and DESKTOP values at the top to look like this instead:

    - -

    -PROFILE="Roaming-Workstation"
    -DESKTOP="lxde"
    -

    - -

    The script could even become useful to set up Debian Edu servers in -the cloud, by starting with a virtual Debian installation at some -virtual hosting service and setting up all the services on first -boot.
