There are lots of things that could be wrong. To confirm that the
X11/OpenGL GLX extension is missing, run the glxinfo program from the
mesa-utils package (if you need to install mesa-utils, installing the
associated dependencies might solve your problem) -- it should fail.
Next examine /var/log/Xorg.0.log to see the error the X11 server has
loading the GLX extension. Fix that error, restart the X11 server, and
repeat until the glxinfo program works. Then Chimera should work too.
Last bit of advice, a simple thing to try is to (re)install the graphics
driver. If you have AMD/ATI or NVIDIA graphics, we strongly recommend
that you install the proprietary driver that is installed with the
Additional Drivers tool in the System Settings dialog. If you have
Intel graphics and glxinfo works, but Chimera doesn't, then make sure
you have all the Ubuntu patches installed. But even if you keep your
system up-to-date, if you have Intel graphics, you should switch to
newer versions of Ubuntu when they come out -- for instance, today, you
should upgrade to 12.10, and I'd recommend 13.04 when it comes out, /ad
infinitum/ or at least for the next 5 years, until the Intel graphics
driver is much less buggy (it has drastically improved in the last
couple of years, but there is much more being done).
