Hi,
Yes, getting OpenGL to work can be a bit painful… I assume you’ve already had a look through this wiki post on the topic.
First thing is to figure out what hardware you have installed:
lspci -v
Look for the ‘VGA compatible controller’ line.
Next is to make sure you’re running locally, not over a network connection – mrview will not (easily) work over an X11 connection unfortunately.
At this point, we’ll probably need more information about what’s going on with your OpenGL setup. The best source of information is to run:
glxinfo
and post the full output here for us to inspect. Hopefully that’ll provide some insight into the problem…
