Hi,

I'm currently trying to set up Debian (Lenny) to run on a flat panel,
touch screen PC.

The graphics card uses an Intel 945GME chipset. Unfortunately whenever I
try and start Xorg using the intel drivers all I get is a blank screen
(literally, no mouse cursor or anything). The screen flickers briefly
and then goes completely dark.

I don't think X has crashed - I can use CTRL+ALT+BACKSPACE to quit. If I
use the vesa drivers, the screen displays fine - although obviously I
would like to get the intel drivers working.

Out of desperation, I installed a copy of Ubuntu 9.10 just to see if
that would work and that seems to work fine.

Now, since this is to be a production machine and stability is an issue
we really want to get Debian Stable working on it if possible. Can
anyone give me any suggestions if it's going to be possible, and if so
what am I doing wrong?

Thanks,

L.

Instead of guessing, use ps to find out if it is still running.

Have you looked at the difference in the /var/log/Xorg.0.log
when using the intel module compared to the vesa module?

It SHOULD work out the box, however I got much better performance buy
using the latest 2.6.30 kernel, available on lenny stable via backports.

oh..and the reason is the latest intel drivers only work properly with
the latest kernels..Mine did work, on the stock stable, but sowly..

YMMV

I fixed it.

Turns out that this particular LCD display is connected to the SDVO
port. However, the Intel drivers in Lenny have a bug that stop them
using the port. I found this fix:

http://www.mail-archive.com/debian-x(a)lists.debian.org/msg84753.html

...and used the patch to update the xserver-xorg-video-intel package.
Rebuilding and reinstalling the updated package solved the problem.
