Hi all Simple question is if it is possible, on a single machine with multiple GPUs, running different X servers on those GPUs, for multiple users to use vglrun at the same time? This is our current setup:
1 machine with 4 Nvidia K80 cards (latest drivers), running CentOS 7, VirtualGL 2.5.2, TightVNC, and Mate Desktop. We have 2 xorg.conf (2 cards configured on each xorg.conf), and currently we are testing whether we can bring up 2 desktop sessions via VNC. The desktop loads, and we can see two different X servers running on those 4 cards and the VNC servers running on different displays. The issue is with VirtualGL. The first user can do startx and run vglrun glxgears, this will work fine. When the second user startx, the first user's vglrun session will be terminated with this error: [VGL] ERROR: OpenGL error 0x0502 [VGL] ERROR: in readpixels--- [VGL] 439: Could not read pixels The first user can run vglrun again once the second user stops their X session. My understanding is that with our setup, this should be do-able, right? Thanks. -- You received this message because you are subscribed to the Google Groups "VirtualGL User Discussion/Support" group.
