    OpenGL not functional, glxgears produces black screen. How to debug?

    How do I gather more debugging info to post?

    I have two video cards, a Geforce 460 and a Geforce 6600. The Geforce 6600 has worked fine with OpenGL in the past.

    If I try and run glxgears in a window displayed by the 6600, I get a black window. Sliding the window over to a display used by the 460, and I can see the gears. This is a pretty interesting bug.

    I tried uninstalling the nouveau drivers and installing the lastest drivers from the ppa. (304.37)

    Same exact problem.

    Black OpenGL window on one screen, but not the other two.
