- KDM fail at boot with NVidia cards - and no one try to fix it? + LUMA, a very nice LDAP GUI
- 1st June 2010 + 28th June 2010
-

It is strange to watch how a bug in Debian causing KDM to fail to -start at boot when an NVidia video card is used is handled. The -problem seem to be that the nvidia X.org driver uses a long time to -initialize, and this duration is longer than kdm is configured to -wait.

+

The last few days I have been looking into the status of the LDAP +directory in Debian Edu, and in the process I started to miss a GUI +tool to browse the LDAP tree. The only one I was able to find in +Debian/Squeeze and Lenny is +LUMA, which has proved to +be a great tool to get a overview of the current LDAP directory +populated by default in Skolelinux. Thanks to it, I have been able to +find empty and obsolete subtrees, misplaced objects and duplicate +objects. It will be installed by default in Debian/Squeeze. If you +are working with LDAP, give it a go. :)

-

I came across two bugs related to this issue, -#583312 initially filed -against initscripts and passed on to nvidia-glx when it became obvious -that the nvidia drivers were involved, and -#524751 initially filed against -kdm and passed on to src:nvidia-graphics-drivers for unknown reasons.

+

I did notice one problem with it I have not had time to report to +the BTS yet. There is no .desktop file in the package, so the tool do +not show up in the Gnome and KDE menus, but only deep down in in the +Debian submenu in KDE. I hope that can be fixed before Squeeze is +released.

-

To me, it seem that no-one is interested in actually solving the -problem nvidia video card owners experience and make sure the Debian -distribution work out of the box for these users. The nvidia driver -maintainers expect kdm to be set up to wait longer, while kdm expect -the nvidia driver maintainers to fix the driver to start faster, and -while they wait for each other I guess the users end up switching to a -distribution that work for them. I have no idea what the solution is, -but I am pretty sure that waiting for each other is not it.

+

I have not yet been able to get it to modify the tree yet. I would +like to move objects and remove subtrees directly in the GUI, but have +not found a way to do that with LUMA yet. So in the mean time, I use +ldapvi for that.

-

I wonder why we end up handling bugs this way.

+

If you have tips on other GUI tools for LDAP that might be useful +in Debian Edu, please contact us on debian-edu@lists.debian.org.

+ +

Update 2010-06-29: Ross Reedstrom tipped us about the +gq package as a +useful GUI alternative. It seem like a good tool, but is unmaintained +in Debian and got a RC bug keeping it out of Squeeze. Unless that +changes, it will not be an option for Debian Edu based on Squeeze.

Det står dårlig til med toget når en finner på å la det -kappkjøre -med sykkel... Jeg tror det trengs strukturendringer for å få -fikset på togproblemene i Norge.

A while back, I +complained +about the fact that it is not possible with the provided schemas +for storing DNS and DHCP information in LDAP to combine the two sets +of information into one LDAP object representing a computer.

-

Mon tro hva toglinje mellom Narvik og Tromsø ville hatt slags -effekt på området der?

+

In the mean time, I discovered that a simple fix would be to make +the dhcpHost object class auxiliary, to allow it to be combined with +the dNSDomain object class, and thus forming one object for one +computer when storing both DHCP and DNS information in LDAP.

+ +

If I understand this correctly, it is not safe to do this change +without also changing the assigned number for the object class, and I +do not know enough about LDAP schema design to do that properly for +Debian Edu.

+ +

Anyway, for future reference, this is how I believe we could change +the +DHCP +schema to solve at least part of the problem with the LDAP schemas +available today from IETF.

- Sitesummary tip: Listing computer hardware models used at site + Calling tasksel like the installer, while still getting useful output
- 3rd June 2010 + 16th June 2010
-

When using sitesummary at a site to track machines, it is possible -to get a list of the machine types in use thanks to the DMI -information extracted from each machine. The script to do so is -included in the sitesummary package, and here is example output from -the Skolelinux build servers:

+

A few times I have had the need to simulate the way tasksel +installs packages during the normal debian-installer run. Until now, +I have ended up letting tasksel do the work, with the annoying problem +of not getting any feedback at all when something fails (like a +conffile question from dpkg or a download that fails), using code like +this: 

-maintainer:~# /usr/lib/sitesummary/hardware-model-summary
-  vendor                    count
-  Dell Computer Corporation     1
-    PowerEdge 1750              1
-  IBM                           1
-    eserver xSeries 345 -[8670M1X]-     1
-  Intel                         2
-  [no-dmi-info]                 3
-maintainer:~#
+export DEBIAN_FRONTEND=noninteractive
+tasksel --new-install
-

The quality of the report depend on the quality of the DMI tables -provided in each machine. Here there are Intel machines without model -information listed with Intel as vendor and no model, and virtual Xen -machines listed as [no-dmi-info]. One can add -l as a command line -option to list the individual machines.

+This would invoke tasksel, let its automatic task selection pick the +tasks to install, and continue to install the requested tasks without +any output what so ever. -

A larger list is -available from the the -city of Narvik, which uses Skolelinux on all their shools and also -provide the basic sitesummary report publicly. In their report there -are ~1400 machines. I know they use both Ubuntu and Skolelinux on -their machines, and as sitesummary is available in both distributions, -it is trivial to get all of them to report to the same central -collector.

+Recently I revisited this problem while working on the automatic +package upgrade testing, because tasksel would some times hang without +any useful feedback, and I want to see what is going on when it +happen. Then it occured to me, I can parse the output from tasksel +when asked to run in test mode, and use that aptitude command line +printed by tasksel then to simulate the tasksel run. I ended up using +code like this: + +
+export DEBIAN_FRONTEND=noninteractive
+cmd="$(in_target tasksel -t --new-install | sed 's/debconf-apt-progress -- //')"
+$cmd
+
+ +

The content of $cmd is typically something like "aptitude -q +--without-recommends -o APT::Install-Recommends=no -y install +~t^desktop$ ~t^gnome-desktop$ ~t^laptop$ ~pstandard ~prequired +~pimportant", which will install the gnome desktop task, the +laptop task and all packages with priority standard , required and +important, just like tasksel would have done it during +installation.

+ +

A better approach is probably to extend tasksel to be able to +install packages without using debconf-apt-progress, for use cases +like this.

- A manual for standards wars... + Vinmonopolet bryter loven åpenlyst - og flere planlegger å gjøre det samme
- 6th June 2010 + 16th June 2010
-

Via the -blog -of Rob Weir I came across the very interesting essay named -The Art of -Standards Wars (PDF 25 pages). I recommend it for everyone -following the standards wars of today.

+

Dagbladet +melder at Vinmonopolet med bakgrunn i vekterstreiken som pågår i +Norge for tiden, har bestemt seg for med vitende og vilje å bryte +sentralbanklovens paragraf 14 ved å nekte folk å betale med +kontanter, og at flere butikker planlegger å følge deres eksempel. +Jeg synes det er hårreisende hvis de slipper unna med et slikt +soleklart lovbrudd, og lurer på hva slags muligheter jeg vil ha hvis +jeg blir nektet å handle med kontanter. Jeg handler i hovedsak med +kontanter selv, da jeg anser det som en borgerrett å kunne handle +anonymt uten at det blir registrert. For meg er det et angrep på mitt +personvern å nekte å ta imot kontant betaling.

+ +

Paragrafen +i sentralbankloven lyder:

+ +
+

§ 14. Tvungent betalingsmiddel

+ +

Bankens sedler og mynter er tvungent betalingsmiddel i Norge. Ingen +er pliktig til i én betaling å ta imot mer enn femogtyve mynter av +hver enhet.

+ +

Sterkt skadde sedler og mynter er ikke tvungent +betalingsmiddel. Banken gir nærmere forskrifter om erstatning for +bortkomne, brente eller skadde sedler og mynter.

+ +

Selv om en avtale inneholder klausul om betaling av en +pengeforpliktelse i gullverdi, kan skyldneren frigjøre seg med tvungne +betalingsmidler uten hensyn til denne klausul.

+
+ +

Det er med bakgrunn i denne lovet ikke tillatt å nekte å ta imot +kontakt betaling. Det er en lov jeg har sans for, og som jeg mener må +håndheves strengt.

- Upstart or sysvinit - as init.d scripts see it + Officeshots taking shape
- 6th June 2010 + 13th June 2010
-

If Debian is to migrate to upstart on Linux, I expect some init.d -scripts to migrate (some of) their operations to upstart job while -keeping the init.d for hurd and kfreebsd. The packages with such -needs will need a way to get their init.d scripts to behave -differently when used with sysvinit and with upstart. Because of -this, I had a look at the environment variables set when a init.d -script is running under upstart, and when it is not.

+

For those of us caring about document exchange and +interoperability, OfficeShots +is a great service. It is to ODF documents what +BrowserShots is for web +pages.

-

With upstart, I notice these environment variables are set when a -script is started from rcS.d/ (ignoring some irrelevant ones like -COLUMNS):

+

A while back, I was contacted by Knut Yrvin at the part of Nokia +that used to be Trolltech, who wanted to help the OfficeShots project +and wondered if the University of Oslo where I work would be +interested in supporting the project. I helped him to navigate his +request to the right people at work, and his request was answered with +a spot in the machine room with power and network connected, and Knut +arranged funding for a machine to fill the spot. The machine is +administrated by the OfficeShots people, so I do not have daily +contact with its progress, and thus from time to time check back to +see how the project is doing.

-PREVLEVEL=
-RUNLEVEL=
-runlevel=S

With sysvinit, these environment variables are set for the same -script.

- -
-INIT_VERSION=sysvinit-2.88
-previous=N
-PREVLEVEL=N
-RUNLEVEL=S
-runlevel=S
-
- -

The RUNLEVEL and PREVLEVEL environment variables passed on from -sysvinit are not set by upstart. Not sure if it is intentional or not -to not be compatible with sysvinit in this regard.

- -

For scripts needing to behave differently when upstart is used, -looking for the UPSTART_JOB environment variable seem to be a good -choice.

+

Today I had a look, and was happy to see that the Dell box in our +machine room now is the host for several virtual machines running as +OfficeShots factories, and the project is able to render ODF documents +in 17 different document processing implementation on Linux and +Windows. This is great.

- Skolelinux er laget for sentraldrifting, naturligvis + Lenny->Squeeze upgrades, removals by apt and aptitude
- 9th June 2010 + 13th June 2010

Det er merkelig hvordan myter om Skolelinux overlever. En slik -myte er at Skolelinux ikke kan sentraldriftes og ha sentralt plasserte -tjenermaskiner. I siste Computerworld Norge er -IT-sjef -Viggo Billdal i Steinkjer intervjuet, og forteller uten -blygsel:

+

My +testing +of Debian upgrades from Lenny to Squeeze continues, and I've +finally made the upgrade logs available from +http://people.skolelinux.org/pere/debian-upgrade-testing/. +I am now testing dist-upgrade of Gnome and KDE in a chroot using both +apt and aptitude, and found their differences interesting. This time +I will only focus on their removal plans.

-

Vi hadde Skolelinux, men det har vi sluttet med. Vi testet -om det lønte seg med Microsoft eller en åpen plattform. Vi fant ut at -Microsoft egentlig var totalt sett bedre egnet. Det var store -driftskostnader med Skolelinux, blant annet på grunn av -desentraliserte servere. Det var komplisert, så vi gikk vekk fra det -og bruker nå bare Windows.

+

After installing a Gnome desktop and the laptop task, apt-get wants +to remove 72 packages when dist-upgrading from Lenny to Squeeze. The +surprising part is that it want to remove xorg and all +xserver-xorg-video* drivers. Clearly not a good choice, but I am not +sure why. When asking aptitude to do the same, it want to remove 129 +packages, but most of them are library packages I suspect are no +longer needed. Both of them want to remove bluetooth packages, which +I do not know. Perhaps these bluetooth packages are obsolete?

-

En rask -sjekk mot den norske brukerlista i Skolelinuxprosjektet forteller -at Steinkjers forsøk foregikk fram til 2004/2005, og at Røysing skole -i Steinkjer skal ha vært svært fornøyd med Skolelinux men at kommunen -overkjørte skolen og krevde at de gikk over til Windows. Et søk på -nettet sendte meg til -Dagens -IT nr. 18 2005 hvor en kan lese på side 18:

+

For KDE, apt-get want to remove 82 packages, among them kdebase +which seem like a bad idea and xorg the same way as with Gnome. Asking +aptitude for the same, it wants to remove 192 packages, none which are +too surprising.

-

Inge Tømmerås ved Røysing skole i Steinkjer kjører ennå -Microsoft, men forteller at kompetanseutfordringen med Skolelinux ikke -var så stor. ­ Jeg syntes Skolelinux var utrolig lett å drifte uten -forkunnskaper. Men man må jo selvsagt ha tilgang på ekstern kompetanse -til installasjoner og maskinvarefeil, sier Tømmerås.

+

I guess the removal of xorg during upgrades should be investigated +and avoided, and perhaps others as well. Here are the complete list +of planned removals. The complete logs is available from the URL +above. Note if you want to repeat these tests, that the upgrade test +for kde+apt-get hung in the tasksel setup because of dpkg asking +conffile questions. No idea why. I worked around it by using +'echo >> /proc/pidofdpkg/fd/0' to tell dpkg to +continue.

Det beste med Skulelinux er halvtjukke klientar. Dei treng ikkje -harddisk og brukar minimalt med ressursar på tenaren fordi dei køyrer -programma lokalt. Eit klasserom med 30 sju-åtte år gamle maskiner har -mykje meir CPU og RAM totalt enn nokon moderne tenar til under -millionen. Det trengst to kommandoar på den sentrale tenaren for å -oppdatere alle klientane, både tynne og halvtjukke. Vi har ingen -problem med diskar som ryk heller, som var eit problem før fordi -elevane sat og sparka i maskinene. Og dei krev lite bandbreidde i -nettet, so det er fullt mogleg å køyre slike på småskular med trege -linjer mot tenaren på ein større skule.

- Lenny->Squeeze upgrades, removals by apt and aptitude -
-
- 13th June 2010 -
-
-

My -testing -of Debian upgrades from Lenny to Squeeze continues, and I've -finally made the upgrade logs available from -http://people.skolelinux.org/pere/debian-upgrade-testing/. -I am now testing dist-upgrade of Gnome and KDE in a chroot using both -apt and aptitude, and found their differences interesting. This time -I will only focus on their removal plans.

- -

After installing a Gnome desktop and the laptop task, apt-get wants -to remove 72 packages when dist-upgrading from Lenny to Squeeze. The -surprising part is that it want to remove xorg and all -xserver-xorg-video* drivers. Clearly not a good choice, but I am not -sure why. When asking aptitude to do the same, it want to remove 129 -packages, but most of them are library packages I suspect are no -longer needed. Both of them want to remove bluetooth packages, which -I do not know. Perhaps these bluetooth packages are obsolete?

+ Skolelinux er laget for sentraldrifting, naturligvis +
+
+ 9th June 2010 +
+
+

Det er merkelig hvordan myter om Skolelinux overlever. En slik +myte er at Skolelinux ikke kan sentraldriftes og ha sentralt plasserte +tjenermaskiner. I siste Computerworld Norge er +IT-sjef +Viggo Billdal i Steinkjer intervjuet, og forteller uten +blygsel:

-

For KDE, apt-get want to remove 82 packages, among them kdebase -which seem like a bad idea and xorg the same way as with Gnome. Asking -aptitude for the same, it wants to remove 192 packages, none which are -too surprising.

+

Vi hadde Skolelinux, men det har vi sluttet med. Vi testet +om det lønte seg med Microsoft eller en åpen plattform. Vi fant ut at +Microsoft egentlig var totalt sett bedre egnet. Det var store +driftskostnader med Skolelinux, blant annet på grunn av +desentraliserte servere. Det var komplisert, så vi gikk vekk fra det +og bruker nå bare Windows.

-

I guess the removal of xorg during upgrades should be investigated -and avoided, and perhaps others as well. Here are the complete list -of planned removals. The complete logs is available from the URL -above. Note if you want to repeat these tests, that the upgrade test -for kde+apt-get hung in the tasksel setup because of dpkg asking -conffile questions. No idea why. I worked around it by using -'echo >> /proc/pidofdpkg/fd/0' to tell dpkg to -continue.

+

En rask +sjekk mot den norske brukerlista i Skolelinuxprosjektet forteller +at Steinkjers forsøk foregikk fram til 2004/2005, og at Røysing skole +i Steinkjer skal ha vært svært fornøyd med Skolelinux men at kommunen +overkjørte skolen og krevde at de gikk over til Windows. Et søk på +nettet sendte meg til +Dagens +IT nr. 18 2005 hvor en kan lese på side 18:

I Flora kommune køyrer vi Skulelinux på skular med alt frå 15 til +meir enn 500 elevar. Dei store skulane har eigen tenar, for det er +mest praktisk. Eg, som er driftsansvarleg for heile nettet, ser +sjeldan dei tenarane fysisk, men at dei står der gjer skulane mindre +avhengige av eksterne linjer som er trege eller dyre. Dei minste +skulane har ikkje eigen tenar. Å bruke sentral tenar er heller ikkje +noko problem. Småskulane klarar seg fint med 1 mbit-linje til ein +sentral tenar eller tenaren på ein større skule.

apt-get kde 82 +

Det beste med Skulelinux er halvtjukke klientar. Dei treng ikkje +harddisk og brukar minimalt med ressursar på tenaren fordi dei køyrer +programma lokalt. Eit klasserom med 30 sju-åtte år gamle maskiner har +mykje meir CPU og RAM totalt enn nokon moderne tenar til under +millionen. Det trengst to kommandoar på den sentrale tenaren for å +oppdatere alle klientane, både tynne og halvtjukke. Vi har ingen +problem med diskar som ryk heller, som var eit problem før fordi +elevane sat og sparka i maskinene. Og dei krev lite bandbreidde i +nettet, so det er fullt mogleg å køyre slike på småskular med trege +linjer mot tenaren på ein større skule.

- Officeshots taking shape + Upstart or sysvinit - as init.d scripts see it
- 13th June 2010 + 6th June 2010
-

For those of us caring about document exchange and -interoperability, OfficeShots -is a great service. It is to ODF documents what -BrowserShots is for web -pages.

+

If Debian is to migrate to upstart on Linux, I expect some init.d +scripts to migrate (some of) their operations to upstart job while +keeping the init.d for hurd and kfreebsd. The packages with such +needs will need a way to get their init.d scripts to behave +differently when used with sysvinit and with upstart. Because of +this, I had a look at the environment variables set when a init.d +script is running under upstart, and when it is not.

+ +

With upstart, I notice these environment variables are set when a +script is started from rcS.d/ (ignoring some irrelevant ones like +COLUMNS):

+ +
+DEFAULT_RUNLEVEL=2
+previous=N
+PREVLEVEL=
+RUNLEVEL=
+runlevel=S
+UPSTART_EVENTS=startup
+UPSTART_INSTANCE=
+UPSTART_JOB=rc-sysinit
+
-

A while back, I was contacted by Knut Yrvin at the part of Nokia -that used to be Trolltech, who wanted to help the OfficeShots project -and wondered if the University of Oslo where I work would be -interested in supporting the project. I helped him to navigate his -request to the right people at work, and his request was answered with -a spot in the machine room with power and network connected, and Knut -arranged funding for a machine to fill the spot. The machine is -administrated by the OfficeShots people, so I do not have daily -contact with its progress, and thus from time to time check back to -see how the project is doing.

+

With sysvinit, these environment variables are set for the same +script.

-

Today I had a look, and was happy to see that the Dell box in our -machine room now is the host for several virtual machines running as -OfficeShots factories, and the project is able to render ODF documents -in 17 different document processing implementation on Linux and -Windows. This is great.

+
+INIT_VERSION=sysvinit-2.88
+previous=N
+PREVLEVEL=N
+RUNLEVEL=S
+runlevel=S
+
+ +

The RUNLEVEL and PREVLEVEL environment variables passed on from +sysvinit are not set by upstart. Not sure if it is intentional or not +to not be compatible with sysvinit in this regard.

+ +

For scripts needing to behave differently when upstart is used, +looking for the UPSTART_JOB environment variable seem to be a good +choice.

Dagbladet -melder at Vinmonopolet med bakgrunn i vekterstreiken som pågår i -Norge for tiden, har bestemt seg for med vitende og vilje å bryte -sentralbanklovens paragraf 14 ved å nekte folk å betale med -kontanter, og at flere butikker planlegger å følge deres eksempel. -Jeg synes det er hårreisende hvis de slipper unna med et slikt -soleklart lovbrudd, og lurer på hva slags muligheter jeg vil ha hvis -jeg blir nektet å handle med kontanter. Jeg handler i hovedsak med -kontanter selv, da jeg anser det som en borgerrett å kunne handle -anonymt uten at det blir registrert. For meg er det et angrep på mitt -personvern å nekte å ta imot kontant betaling.

Paragrafen -i sentralbankloven lyder:

-

§ 14. Tvungent betalingsmiddel

- -

Bankens sedler og mynter er tvungent betalingsmiddel i Norge. Ingen -er pliktig til i én betaling å ta imot mer enn femogtyve mynter av -hver enhet.

- -

Sterkt skadde sedler og mynter er ikke tvungent -betalingsmiddel. Banken gir nærmere forskrifter om erstatning for -bortkomne, brente eller skadde sedler og mynter.

- -

Selv om en avtale inneholder klausul om betaling av en -pengeforpliktelse i gullverdi, kan skyldneren frigjøre seg med tvungne -betalingsmidler uten hensyn til denne klausul.

Det er med bakgrunn i denne lovet ikke tillatt å nekte å ta imot -kontakt betaling. Det er en lov jeg har sans for, og som jeg mener må -håndheves strengt.

When using sitesummary at a site to track machines, it is possible +to get a list of the machine types in use thanks to the DMI +information extracted from each machine. The script to do so is +included in the sitesummary package, and here is example output from +the Skolelinux build servers:

-export DEBIAN_FRONTEND=noninteractive
-cmd="$(in_target tasksel -t --new-install | sed 's/debconf-apt-progress -- //')"
-$cmd
+maintainer:~# /usr/lib/sitesummary/hardware-model-summary
+  vendor                    count
+  Dell Computer Corporation     1
+    PowerEdge 1750              1
+  IBM                           1
+    eserver xSeries 345 -[8670M1X]-     1
+  Intel                         2
+  [no-dmi-info]                 3
+maintainer:~#
-

The content of $cmd is typically something like "aptitude -q ---without-recommends -o APT::Install-Recommends=no -y install -~t^desktop$ ~t^gnome-desktop$ ~t^laptop$ ~pstandard ~prequired -~pimportant", which will install the gnome desktop task, the -laptop task and all packages with priority standard , required and -important, just like tasksel would have done it during -installation.

+

The quality of the report depend on the quality of the DMI tables +provided in each machine. Here there are Intel machines without model +information listed with Intel as vendor and no model, and virtual Xen +machines listed as [no-dmi-info]. One can add -l as a command line +option to list the individual machines.

-

A better approach is probably to extend tasksel to be able to -install packages without using debconf-apt-progress, for use cases -like this.

+

A larger list is +available from the the +city of Narvik, which uses Skolelinux on all their shools and also +provide the basic sitesummary report publicly. In their report there +are ~1400 machines. I know they use both Ubuntu and Skolelinux on +their machines, and as sitesummary is available in both distributions, +it is trivial to get all of them to report to the same central +collector.

- Idea for a change to LDAP schemas allowing DNS and DHCP info to be combined into one object + Togsatsing på norsk, mot sykkel
- 24th June 2010 + 2nd June 2010
-

A while back, I -complained -about the fact that it is not possible with the provided schemas -for storing DNS and DHCP information in LDAP to combine the two sets -of information into one LDAP object representing a computer.

- -

In the mean time, I discovered that a simple fix would be to make -the dhcpHost object class auxiliary, to allow it to be combined with -the dNSDomain object class, and thus forming one object for one -computer when storing both DHCP and DNS information in LDAP.

- -

If I understand this correctly, it is not safe to do this change -without also changing the assigned number for the object class, and I -do not know enough about LDAP schema design to do that properly for -Debian Edu.

- -

Anyway, for future reference, this is how I believe we could change -the -DHCP -schema to solve at least part of the problem with the LDAP schemas -available today from IETF.

I very much welcome clues on how to do this properly for Debian -Edu/Squeeze. We provide the DHCP schema in our debian-edu-config -package, and should thus be free to rewrite it as we see fit.

- LUMA, a very nice LDAP GUI + KDM fail at boot with NVidia cards - and no one try to fix it?
- 28th June 2010 + 1st June 2010
-

The last few days I have been looking into the status of the LDAP -directory in Debian Edu, and in the process I started to miss a GUI -tool to browse the LDAP tree. The only one I was able to find in -Debian/Squeeze and Lenny is -LUMA, which has proved to -be a great tool to get a overview of the current LDAP directory -populated by default in Skolelinux. Thanks to it, I have been able to -find empty and obsolete subtrees, misplaced objects and duplicate -objects. It will be installed by default in Debian/Squeeze. If you -are working with LDAP, give it a go. :)

- -

I did notice one problem with it I have not had time to report to -the BTS yet. There is no .desktop file in the package, so the tool do -not show up in the Gnome and KDE menus, but only deep down in in the -Debian submenu in KDE. I hope that can be fixed before Squeeze is -released.

+

It is strange to watch how a bug in Debian causing KDM to fail to +start at boot when an NVidia video card is used is handled. The +problem seem to be that the nvidia X.org driver uses a long time to +initialize, and this duration is longer than kdm is configured to +wait.

-

I have not yet been able to get it to modify the tree yet. I would -like to move objects and remove subtrees directly in the GUI, but have -not found a way to do that with LUMA yet. So in the mean time, I use -ldapvi for that.

+

I came across two bugs related to this issue, +#583312 initially filed +against initscripts and passed on to nvidia-glx when it became obvious +that the nvidia drivers were involved, and +#524751 initially filed against +kdm and passed on to src:nvidia-graphics-drivers for unknown reasons.

-

If you have tips on other GUI tools for LDAP that might be useful -in Debian Edu, please contact us on debian-edu@lists.debian.org.

+

To me, it seem that no-one is interested in actually solving the +problem nvidia video card owners experience and make sure the Debian +distribution work out of the box for these users. The nvidia driver +maintainers expect kdm to be set up to wait longer, while kdm expect +the nvidia driver maintainers to fix the driver to start faster, and +while they wait for each other I guess the users end up switching to a +distribution that work for them. I have no idea what the solution is, +but I am pretty sure that waiting for each other is not it.

-

Update 2010-06-29: Ross Reedstrom tipped us about the -gq package as a -useful GUI alternative. It seem like a good tool, but is unmaintained -in Debian and got a RC bug keeping it out of Squeeze. Unless that -changes, it will not be an option for Debian Edu based on Squeeze.

+

I wonder why we end up handling bugs this way.
