I feel your pain (I think ...I didn't see the original posting). It may be that glx.so is the culprit. Sender: timh@suse.com Date: Sat, 31 Mar 2001 22:46:23 -0800 From: Tim Hanson <tjhanson@home.com> Jonathan Drews wrote:

Hi Tim:

First check to see that Load "GLX" is in your modules section of /etc/X11/XF86Config. If that is there look at /var/log/XFree86.0.log and see if there are any entries prefixed with (EE) or (WW). This should give a clue. If the remarks in /var/log/XFree86.0.log are too cryptic cut and past the (EE) section(s) to an e-mail and send it to the list. I myself am not an X expert but I hope this helps.

I get an error when I start X that puzzles me. it is:

Xlib: extension "GLX" missing on display ":0.0".

I get the same error when I run some screensaver graphics. I don't really know much about it other than to reinstall xf86_glx (which didn't help). Does anyone else know about a fix for this?
