bvc Posted April 18, 2003 Report Share Posted April 18, 2003 Most likely it's either that XF86Config-4 isn't edited corrrectly, or your resolution and/or depth is too high. Check that the modules and device sections are correct and that if you have a really high res/depth (forgot the exact limit for glxgears) try lowering them or one of them. I got the same message after my Slackware9.0 install that had me at 1280x1024 32DefaultColorDepth (I think that's what it was). When I changed it to 24 all was well.

Pzatch Posted April 18, 2003 Report Share Posted April 18, 2003 I believe that the new driver rewrites the xf86config-4 file back to what it thinks it should be. You'll need to go in and change it back to point at the new GLX driver file. It's been a while since I had to do this one. Don't Nvidia test this stuff on Mandrake?

Guest ndeb Posted April 18, 2003 Report Share Posted April 18, 2003 In the file /etc/X11/XF86Config-4, in the section, look for the shown line: Section "Module" Load "dbe" # Double-Buffering Extension Load "v4l" # Video for Linux Load "extmod" Load "type1" Load "freetype" Load "glx" # 3D layer <------ THIS LINE EndSection If the line for module glx is commented or is just not there, then the GLX extension will be missing.

Guest JaseP Posted April 22, 2003 Report Share Posted April 22, 2003 Also, check to see that the glx module link points to the actual nVidia glx library. Sometimes the problem is that the module's link doesn't point to the correct library. Quote Link to comment Share on other sites More sharing options...
