Old ATI card and xorg/lightdm

Asked by PBS on 2013-05-26

I have installed Xubuntu 13.04 on a laptop with an ancient ATI 3D Rage graphics card (a Sony Vaio PCG-972M). However the graphics only works when the vesa driver is set in xorg.conf. With the 'ati' driver wrapper it reaches a console saying 'Starting lightdm display manager' then the screen goes black every few seconds as it repeatedly restarts. Below are some interesting snippets about this from Xorg.0.log and lightdm.log. Is it a hopeless case?

try blacklisting the driver

If you have an xorg.conf file (probably you have one), rename it to xorg.conf.old and try to start without xorg.conf at all.

Then post again your xorg.conf file. Full results it would be better.

    sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.old

I restarted without xorg.conf and it again reached a blinking black screen. No new xorg.conf is generated. Here is the only xorg.conf that will work at all.

This is the full contents of x-0.log from /var/log/lightdm, showing how X crashes when loading the GLX extension.

You may need an xorg.conf file to define the display better
