 Posted: Thu Aug 10, 2017 3:01 pm Post subject: couldn't find RGB GLX visual or fbconfig |
 |
|
While developing a small OpenGL3+ game app, I'm getting the following on startup. So here's the details of just trying to run glxgears.
Thoughts?
| Code: |
$ sudo eselect mesa list

If you're using nvidia-drivers you can't use gallium, switch mesa to classic.

Make sure you set eveything to nvidia using eselect. Then do the following:
| Code: | mv /usr/lib64/xorg/modules/extensions/libglx.so /usr/lib64/xorg/modules/extensions/libglx.so.org
ln -snf /usr/lib/opengl/nvidia/extensions/libglx.so /usr/lib64/xorg/modules/extensions/libglx.so |
