[chimera-dev] Xlib: extension "NV-GLX" missing on display ":0".

[Thomas Evangelidis]

After installing the proprietary NVIDIA drivers I am getting the following
error message on start up:

Error initializing OpenGL: X server is missing OpenGL GLX extension
Couldn't configure togl widget

Does this say anything different from the one I reported before?
