Hi,<br>I am having problems running 3-d applications on my system. I have fc3 installed on a p4 2.4ghz intel 865 m/b with 32 mb inbuilt graphics memory. Eearlier my 3-d applications were running fine. But, recently I installed nvidia drivers to test my friend's new graphics card and it was working fine. I had made changes to
xorg.conf to enable the drivers. Now, I dont have the graphics card anymore and I restored my xorg.conf back. But now graphics is not working for me. On starting "glxgears", I get the following errors...<br>---<br>
Xlib: extension "GLX" missing on display ":0.0".<br>glxgears: Error: couldn't get an RGB, Double-buffered visual.<br>---<br><br>This is my xorg.conf file<br><br># Xorg configuration created by system-config-display
