Title:
[amdgpu + nvidia PCI passthrough] Screen flickering on ultra wide
Status in xorg-server package in Ubuntu:
Expired
Status in xserver-xorg-video-amdgpu package in Ubuntu:
Expired
Bug description:
I'm running 18.04 including all updates on an LG 38WK95C at
3840x1600@75. I'm experiencing constant flickering on screen when
setting the refresh rate to 75Hz in settings. When I set to refresh
rate to 60Hz, the flicking is gone.
When enabeling freesync in the monitor's settings, the 60Hz isn't
available and the only choices are 29.99Hz or 75Hz, which again causes
flickering.
This looks like the same issue in bug #1749975.
