Public bug reported:
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.
