Bug ID: 202799
Summary: amd/dc: right monitor sometimes never comes back up on
dual-display setup after locking session
Product: Drivers
Version: 2.5
Kernel Version: 5.0
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Video(DRI - non Intel)
Assignee: drivers_video-dri@kernel-bugs.osdl.org
Reporter: libcg@protonmail.com
Regression: No
Created attachment 281547
--> https://bugzilla.kernel.org/attachment.cgi?id=281547&action=edit
xrandr --props output
- linux 5.0 (4.20 also had the same issue)
- xf86-video-amdgpu 18.1.0
- GNOME 3.30
Left screen is a Dell U2412M (1920x1200), right screen is a Dell P2715Q (4K
monitor set at 2560x1440, primary). GPU is RX 580.
Steps to reproduce:
- Lock session, screens turn off
- After a while, press a key to turn the screens back on again
- When the left screen lights up first, the system only displays an image on
the left screen. The right screen lights up afterwards but goes back to sleep
because it's getting no signal, although xrandr still recognizes it. I need to
manually turn off the right screen and back on again to get it to reconfigure.
When using `amdgpu.dc=0`, this issue disappears.

Please attach the corresponding Xorg log file and full output of dmesg,
preferably captured after the problem occurred.

--- Comment #6 from Nicholas Kazlauskas (nicholas.kazlauskas@amd.com) ---
It might be useful to have a dmesg log from after the problem occurred with
drm.debug=4 set in your kernel boot parameters.
