Hi. I'm running in to an issue where VirtualGL works flawlessly for a while after booting the system, but then develops problems after a short time (5 mins or so). Using glxgears as an example, these problems manifests as either a black window or corrupted images being displayed by the client. nvidia-smi shows glxgears running on the GPU whilst the black/corrupted window is shown, though the framerate reported by glxgears is very low (~0.3FPS). Other applications also initially run perfectly, but then fail to start or show corrupted graphics a few minutes following boot.
My configuration: - CentOS 7 - Nvidia Quadro P2000, passed through to a VM running VirtualGL via VFIO. - Latest VirtualGL dev version (2.6.80-20190717) - Latest TurboVNC dev verison (2.2.80-20190803) Earlier versions of VirtualGL/TurboVNC show the same symptoms. A variety of Nvidia driver versions also show the same symptoms. Running vglrun with the +v verbose flag shows no errors. This has been a bit of a tricky one to diagnose, so any thoughts would be useful. Cheers Sam. -- You received this message because you are subscribed to the Google Groups "VirtualGL User Discussion/Support" group.
