Hi,

I'm trying to configure VirtualGL to be able to use visualization software 
remotely, and it more or less works, but I'm not sure things are perfectly 
configured, so I'm hoping someone here can give me some guidance.

The setting is as follows: 

Remote machine (deim)
------------------------
Fedora 4.13.11-200.fc26.x86_64
GPU: NVIDIA Corporation GP100GL [Tesla P100 PCIe 12GB] (rev a1)
VirtualGL.x86_64                        2.4-8.fc26 


Workstation (com)
-----------------
ArchLinux with virtualgl 2.5.2-2 installed


Let's try to run glxgears remotely. As you can see below all seems OK (and 
I can see the glxgears turning, but should I worry about that libGL errors? 
(I understand that swrast is for software rendering, so perhaps I don't 
care if it cannot be loaded, but I'm not sure about this.

Any help/pointers appreciated.
