What's your video card and are you sure you have direct rendering enabled?
- Code: Select all
glxinfo | grep direct
Does it say Yes or No?
If no, post the output of /var/log/Xorg.0.log
If yes, do what the post above suggested and make sure you have Aiglx or XGL installed. (Note: You will have to use XGL if you are using the fglrx driver.)
