phsythax · 03-23-2006, 01:38 PM

Code:

GLUT: Fatal Error in 3dfile: OpenGL GLX extension not supported by display: :0.0

is the error i get after trying to run 3dfile, it worked before i tryed to update my graphiccard drivers but now it doesnt.

i have ran

Code:

emerge nvidia-kernel && emerge nvidia-glx

...and...

Code:

emerge --sync && emerge -Du world

but it still doesnt work. What can i do about this? please help.
ps. now im using my old drivers, and i get that error above, before i switched back to my old ones i got a "segmentation fault" when i tried to run 3dfile.

(3dfile can be found here: http://turma.sourceforge.net/software/3dfile/index.html )

In your /etc/xorg.conf file, make sure you have:
load "glx"

in the modules section (there'll be loads of other load commands there, just stick it on the end if not)

i dont got that file but i got /etc/X11/xorg.conf
and it has the load "glx" part in the load modules.

Sorry, yes, I meant that file...suffering from brain rot today

OK, load X as usual, then edit the file /var/log/Xorg.0.log and see if there are any errors reported for GLX. Alternatively, it could be that direct rendering is disabled, in which case check /etc/X11/xorg.conf for the lines:

Section "DRI"
Mode 0666
EndSection

i found this:

Code:

but howcome i don't got the nvidia X driver? i mean, i have ran both emerge nvidia-kernel && emerge nvidia-glx

Driver "nvidia"

You took the words right out of my, uhh, fingers

Log files are so useful - one thing Windows never got right.
