I have a combination that is working now, and this is my primary work
computer.  I'm a contract engineer, and when this thing is down I'm not
earning my pay.  So I really, really don't want to mess with it -- I'm
sorry about that, but I hope you understand.

However, as I get time, I'd be willing to install things on a USB stick
and see if I can't replicate the problem there.

Based on my own experience (I do embedded software work, but I'm just a
user when it comes to Linux) I suspect that the actual problem is not
the new driver itself, but that something in the installation process
diddled with some global OpenGL settings that then broke either the
Radeon driver, or OpenGL itself (I don't know if that makes sense,
because I'm a USER.  Call me if you're designing washing machine motor
drive that buzzes on the spin cycle and I'll help you out, though).

So the process that I'd suggest, if you're willing to help me out with
the details, would be to install an entire pre-November 4 version of
Xubuntu onto a USB stick, verify that OpenGL works, then do the November
4 upgrade, and test OpenGL again.

I do have IT help on hand, whose familiar with Linux -- I just have to
come up with appropriate bribes.  So if it's too hard to describe to a
knowledgeable user, describe it for someone who installs Arch onto a
spare machine so that he can use that as a tool to talk to an obsolete
Sun box that he's installing Gentoo upon -- he'll have the background to
rapidly get things I don't.

Title:
  OpenGL Graphics broken on November 4th upgrades

Status in nvidia-graphics-drivers-340 package in Ubuntu:
  New

Bug description:
  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.

  ubuntu-drivers devices returns

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