Bug ID: 102498 Summary: Monitors blink every 10sec and layout resets after returning from powersave or sleep Product: DRI Version: unspecified Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: fayn@mt2015.com
Created attachment 133913 --> https://bugs.freedesktop.org/attachment.cgi?id=133913&action=edit dmesg
One or both monitors (ASUS much more often) continously blink once in 5-10 seconds. This happens only in linux and not in grub or windows. Second problem is that monitor layout resets to mirrored from extended desktop when monitor returns from powersaving to show lockscreen and I need to rerun xrandr. There are some errors in dmesg, so it is attached. Log is from right after returning from being AFK and giving lockscreen password. This bug is continuation to my previous problem in Bug #102300.
