Which NVIDIA driver are you using? Closed-source nvidia-drivers driver? Open-source nv driver? Open-source nouveau driver? (Look in /etc/X11/xorg.conf or /var/log/Xorg.0.log to check.)
This is a very long shot and probably not the cause of your problem, but check the output of the following command (as root user):
- Code: Select all
eselect mesa list
and change any that are linked to "gallium" to be linked to "classic". Hypothetical example:
- Code: Select all
eselect mesa set 64bit r300 classic
eselect mesa set 64bit sw classic
eselect mesa set 32bit r300 classic
eselect mesa set 32bit r600 classic
eselect mesa set 32bit sw classic
The ATI Radeon links to Gallium3D should have no effect in your case, but I don't know about the '64bit sw' and '32bit sw'. Anyway, it won't do you any harm to put them all to classic, so you may as well try it.
