Hey, so there appears to be some progress as of today's build of amd-staging-drm-next branch. The system I use has 2 external displays, identical, one connected over HDMI another over DVI. Currently: 1. Just after the boot, gamma settings on DVI-connected one are messed up (is this HDR mode?). The settings on the other display, connected over HDMI seem fine. 2. I use Gnome/Ubuntu 18.04, when I enable "Night mode" (i.e. f-lux for Linux thing), it fixes the issue for DVI-connected display. The fix also works after I disable "Night mode". Hope that helps :) Hubert Å?Ä?picki 2018-03-08 15:28 GMT+01:00 Deucher, Alexander <Alexander.Deucher at amd.com>: > + Harry, Leo > > > I saw this as well with tonga.
