Hi,

I got an ancient laptop from a friend; he thinks that with only 512 MiB of RAM it is worthless ;-)

It has a "Intel(R) Pentium(R) 4 CPU 2.80GHz" CPU and the video is "Intel Corporation i845" from "Uniwill Computer Corp". The doc says "Intel® Extreme Graphics"


The video is the problem.

I tested Puppy Wary 5.2 - it works fine. It detects the video card but not the monitor, so I select from a list: 1024x768x16 h31.5-49,5v56-72. This works, fills the entire screen. I don't know if it is the maximum resolution, the documentation does not say (only that is «TFT 14” (N618) or 15” (N619-N620) XGA». The wikipedia lists XGA as "XGA 1024 768 4:3 0.786" (http://en.wikipedia.org/wiki/XGA#XGA_.281024.C3.97768.29) so it seems I have it right.


During installation of openSUSE from DVD went perfect - slow, but uneventful.

But on reboot, the display is incorrect. It looks like this

Area '3' is bright white, '2' is black. The working area is only '1'. It is the same in text mode as in graphical mode.

Using "nomodeset" I get an apparent resolution of 640x480, centered with wide black border, and no white region; thus usable, but much less than what the machine is capable off.

I have removed plymouth and I'm booting to text mode. The normal kernel boot parameters are;

showopts splash=verbose loglevel=3 console=tty1 display=1024x768

which does not work. Without "display=" I get the same results. I have not found documentation for the display option under "/usr/src/linux/Documentation" tree, so I do not know what to try there.


At the moment I use:

showopts splash=verbose console=tty1 loglevel=3 plymouth.enable=0 nomodeset

I have tried:

modeset=0 display=1024x768 --> white region

nomodeset display=1024x768 --> 640*480

nomodeset display=1024*768 --> 640*480

display=1024x768 --> white region


All official updates are applied.



For X, the release notes say to do:

Section "Device"
Identifier "Default Device"
Driver "intellegacy"
EndSection

This makes X not to start:

[ 375.163] (WW) Warning, couldn't open module intellegacy
[ 375.163] (II) UnloadModule: "intellegacy"
[ 375.163] (II) Unloading intellegacy
[ 375.163] (EE) Failed to load module "intellegacy" (module does not exist, 0)
[ 375.163] (EE) No drivers available.


:-O !
