https://bugzilla.kernel.org/show_bug.cgi?id=199139 --- Comment #22 from mistarzy@xxxxxxxxx --- I got rid of the issue by clean installation of Xubuntu 18.04.1 with 4.15. Same kernel on old installation (xubuntu being upgraded over the years from 15.04 to 18.04.1) that I mentioned on 2018-09-14 still has issues. I was trying to find source of the issue but I do not believe that was kernel related. Since on fresh installation everything works fine. Also when switched to mainline https://kernel.ubuntu.com/~kernel-ppa/mainline/v4.20/ no issues found. My skills are limited but would guess is how system is handling amdgpu driver. If you would like me to test something I have both installations available - with and without drm issue. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
