https://bugs.freedesktop.org/show_bug.cgi?id=109246 Jean Delvare changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jdelvare@suse.de --- Comment #28 from Jean Delvare --- Same problem here. Radeon RX 550 with 2 identical Lenovo P27h-10 displays configured in side-by-side mode, one over DisplayPort and one over HDMI, kernel 5.2.11. When the displays go to sleep, the multi-display configuration is lost, displays are in mirror mode when waking up, and I must configure them again. Booting with amdgpu.dc=0 works around the problem (thanks Michel for the hint!) -- You are receiving this mail because: You are the assignee for the bug.
