Dear Maintainer,
I upgraded from Debian 11 to 12, since the upgrade I had this problems,
before it works fine (used Backports-Kernel).
I've connected 2 external Monitor via DisplayPort on a Thinkpad Ultra
Docking station and it happens often (not always) that the Monitor
doesn't wake up after suspend. In the KDE display settings I still see
external monitors. DRM said they are on:
grep . /sys/class/drm/card*-*/dpms
/sys/class/drm/card0-DP-1/dpms:Off
/sys/class/drm/card0-DP-2/dpms:Off
/sys/class/drm/card0-DP-3/dpms:Off
/sys/class/drm/card0-DP-6/dpms:On
/sys/class/drm/card0-DP-7/dpms:On
/sys/class/drm/card0-eDP-1/dpms:Off
/sys/class/drm/card0-HDMI-A-1/dpms:Off
and syslog said:
[drm:dc_link_allocate_mst_payload [amdgpu]] *ERROR* Failure: pbn_per_slot==0
not allowed. Cannot continue, returning DC_UNSUPPORTED_VALUE.
