Re: [Server-devel] XS on ASUS Netbook - Display Problem
Martin, Success... I edited the /boot/grub/menu.lst file so that the kernel line is now kernel /vmlinuz-2.6.27.25-78.2.56.fc9.i686 ro root=UUID=58ef33d6-bd02-4a2c-830b-2515ff9368ed rhgb quiet acpi_osi=Linux acpi_backlight=vendor On the first reboot, the boot process paused for about 30 seconds at the "starting udev" stage. The screen went dim, but when the server was fully booted, the fn+F6 key worked to raise the brightness! On second reboot, the boot process did not pause, and the screen remained bright. Issue solved. You may want to consider adding this to future server releases, assuming that it doesn't cause problems on other platforms.

Re: [Server-devel] XS on ASUS Netbook - Display Problem
Martin, Looking at some Fedora sites, I see where there are many post of problems with the Eee PC and backlighting. Based on what I read, I decided to update the BIOS, and although it didn't fix the problem completely, the screen now has about 10% brightness, so I can actually read it if the room is not too bright. some people have reported a fix in fedora that uses grub kernel options: acpi_osi=Linux acpi_backlight=vendor I will try putting these in the /boot/grub/menu.lst file. Is this the right place? Any suggestions? Andy On Dec 2, 2010, at 10:02 AM, Andra DuPont wrote: > Martin, > Thanks for the suggestion.

Re: [Server-devel] XS on ASUS Netbook - Display Problem
Martin, Thanks for the suggestion. I will run lsmod. After sleeping on it, I think the conflicting driver must be related to the backlighting on the display, not the graphics processor. The Acer and Asus have the same graphics hardware, but the displays are different.

I'd suggest - - run lsmod, it'll tell you what modules are being loaded - one of them will be controlling your video card -- for example an i915 card loads intel_agp, drm and i915 - name those modules in /etc/modules/blacklist.conf so they don't get loaded but I agree with you, it's very strange that you need to go through this dance. cheers, m -- martin.langh...@gmail.com mar...@laptop.org -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
Re: [Server-devel] XS on ASUS Netbook - Display Problem
Martin,
Removing the first line from the 80-drivers.rules keeps the screen from going
dark, but as best I can tell, it also keeps most of the drivers from being
installed. For instance, the ethernet ports are not found when the line is
omitted. The line is:
DRIVER!="?*", ENV{MODALIAS}=="?*", RUN{ignore_error}+="/sbin/modprobe
$env{MODALIAS}"
SUBSYSTEM=="pnp", DRIVER!="?*", ENV{MODALIAS}!="?*", \
As best as I can tell, the command uses modprobe to install the appropriate
drivers from the modules.alias list in /lib/modules/... directory.
So apparently one of the drivers that is installed is conflicting with the
screen brightness.
Do you have any idea where to go from here? I am really surprised because the
Acer Aspire One this I'm using in Kenya now did not have this problem, and it
has the same Intel GMA 3150 graphics processor as this ASUS Eee PC.

Strange! Can you post /var/log/messages and the output from dmesg from
that server, right after booting?

[Server-devel] XS on ASUS Netbook - Display Problem
I have installed XS 0.6 on an ASUS 1005PEB Eee PC. The server is running fine except that the screen went dark at server start-up right after the "starting udev" was displayed on the screen. My screen stays dark and can only be reset by restoring the default bios settings. Then it gets set dark again at server startup at the "starting udev" process. Any idea what rule or other change I could make to keep the screen from going dark? Andy ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
