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

">Packard Bell
25 EasyNote LV
</a
>, Thinkpad X40 and many other laptops.
</p
>
27 <p
>The problem can be worked around two ways. Either by adding
28 i915.invert_brightness=
1 as a kernel option, or by adding a file in
29 /etc/modprobe.d/ to tell modprobe to add the invert_brightness=
1
30 option when it load the i915 kernel module. On Debian and Ubuntu, it
31 can be done by running these commands as root:

34 echo options i915 invert_brightness=
1 | tee /etc/modprobe.d/i915.conf

">a

105 developers did to handle this, and this can give a clue to the KDE
106 developers? Or you know where in KDE the screen brightness is changed
107 during login? If so, please update the BTS report (or get in touch if
108 you do not know how to update BTS).

">Debian Edu, also known as
129 Skolelinux
</a
>, is a Linux distribution based on Debian providing an
130 out-of-the box environment of a completely configured school
131 network. Immediately after installation a school server running all
132 services needed for a school network is set up just waiting for users
133 and machines being added via GOsa², a comfortable Web-UI. A netbooting
134 environment is prepared using PXE, so after initial installation of
135 the main server from CD, DVD or USB stick all other machines can be
136 installed via the network. The provided school server provides LDAP
137 database and Kerberos authentication service, centralized home
138 directories, DHCP server, web proxy and many other services. The

304 by

</a

305 me also was the fact that among the software installed by default,
306 there were many

321 <p

322 community of experts and its precise documentation, as well as the
323 fact that it provides a solution ready to use.
</p

325 <p

330 Edu?
</strong

332 <p
>Maybe the lack of manpower to do lobbying on the
333 project. Sometimes, people who need to take decisions concerning IT do
334 not have all the elements to evaluate properly free software
335 solutions. The fact that support by a company may be difficult to find
336 is probably a problem if the school does not have IT personnel.
</p

338 <p
>One can find support from a company by looking at
339 <a href=
"http://wiki.debian.org/DebianEdu/Help/ProfessionalHelp
">the

</a

341 companies providing support for Debian Edu, like Germany or
342 Norway. This list is easy to find readily from the manual. However,
343 for other countries, like France, the list is empty. I guess that
344 consultants proposing support for Debian would be able to provide some
345 support for Debian Edu as well.

>Jeg jobber til daglig ved
<a href=

">Universitetet
411 i Oslo
</a
>, en institusjon som lenge har vektlagt verdien av åpne
412 standarder og fri programvare. Men noe har endret seg, og for en

414 basert på fri programvare skulle byttes ut med Microsoft Exchange og
415 at Microsoft Outlook skulle bli den best fungerende men antagelig ikke

434 valget av Microsoft Exchange som sentral epostinfrastruktur er et
435 heldig valg for Norges ledende forskningsuniversitet, men at en er mer
