First: I don't know if I'm reporting this against the correct package. The bug report system needs a "unknown package" reporting system, for people who aren't freaking IT experts yet who are still smart enough to notice a real live problem.

I have a Radeon card, but things most definitely broke TODAY immediately after I did a software upgrade.

I use Scilab, which uses OpenGL heavily. After today's upgrade, it was unable to display graphics, reporting

"Caused by: javax.media.opengl.GLException: Profile GL_DEFAULT is not available on X11GraphicsDevice[type .x11, connection :0.0"

The symptom in Scilab was that the graphics window opened, but no graph was drawn upon it. glxinfo is unable to find an RGB visual; I assume that means that GL is broken -- glxinfo certainly works just fine on another machine upon which Scilab also works just fine.

As near as I can tell, the xserver-xorg-video-ati is installed. I have not attempted to change over to fglrx.
