Hi Greg,

Thank you for you reply!

I have glx-utils-8.2.0-3.el7.x86_64 installed. And the glxinfo command gave
a very long list, for the first few lines, it gave this:

name of display: :0
display: :0  screen: 0
direct rendering: Yes
server glx vendor string: NVIDIA Corporation
server glx version string: 1.4

Do you need the rest of the result? It is a really long one. I feel like it
is better to keep it short in the mailing list.
