Why installed Kubuntu 8.04's X failed to start, not Live CD one

Asked by Sancho

I have a computer using VIA on board graphics card. Live CD Kubuntu run perfectly on it. Especially the X. I can login through kdm and even Kubuntu can detect that I have X Video extension (from xvinfo command).

Later, I thought I decided to install that Kubuntu. I was disappointed that KDM could not start. It failed to enter X! It retried 3 times. Every retry showed me some flickers of KDM. But eventually it failed (stopped retrying).

The strange thing was, I had copied Live CD Kubuntu's xorg.conf into the installed version of the same Kubuntu I had. It remained the same.

If I removed the xorg.conf, Kubuntu could start KDM. But xvinfo gave me output "no adaptors present" which means my VIA card has no X video extension.

Because of this problem, I can not start googleearth, playing 3D games and use mplayer nicely.

Why did both Kubuntu not give me the same result? They used the same xorg.conf right? Does anybody get the problem solved?

Some snapshots from log files:
1. kdm.log

(==) Using config file: "/etc/X11/xorg.conf"

Can you post the complete xorg.conf file in /etc/X11/xorg.conf?

You don't seem to be having a driver entry there, try reconfiguring the X-Server by executing:-
sudo dpkg-reconfigure xserver-xorg
select the driver as via, but if it isn't there/or if it doesn't work then choose vesa(although this should be a last resort since there is no 3D acceleration) and any other options you may want, then see if the problem is solved.

Can you help with this problem?

Provide an answer of your own, or ask Sancho for more information if necessary.
