Hi,

I tried opening tkmedit but received the following error:

libGL error: No matching fbConfigs or visuals found

libGL error: failed to load driver: swrast

X Error of failed request: GLXBadContext

Major opcode of failed request: 149 (GLX)

Minor opcode of failed request: 6 (X_GLXIsDirect)

Serial number of failed request: 26

Current serial number in output stream: 25?

From what I've read online, it seems to be a graphics card issue, but I'm unsure how to resolve the problem because I'm using my university's linux cluster.

Thanks for the help.
