VMD-L Mailing List

Well, although this seems not to work for only me currently, I still think
this should be caught from the coders site.

See:
https://devtalk.nvidia.com/default/topic/705344/-solved-sdk-sample5-vs-sampl
e5pp/
http://stackoverflow.com/questions/22810911/how-to-check-if-a-glxcontext-is-
remote-or-local

Indicating there _can_ be a problem and might be distribution/driver
specific.

Also, I'm not installing the nvidia drivers from repository but using the
*.run files, anybody can confirm this?
