Slow OpenGL, can't uninstall Mesa
I installed Mesa earlier today for debugging purposes, and then I tried to uninstall it (I'm using Debian Testing btw). I then reinstalled the NVidia drivers. But now OpenGL stuff runs really slow. When I run glxgears I get about 10 FPS. When I run glxinfo it reports that direct rendering is supported and it says I'm using the Nvidia driver. I've checked the opengl libraries in /usr/lib and they're all pointing to Nvidia's libraries, not mesa's.
What do I need to do?
