Source: linux Followup-For: Bug #1028451 Fwiw there is a general regression with AMDGPU MST on linux 6.1; tracked upstream here: https://gitlab.freedesktop.org/drm/amd/-/issues/2171
As the original report was about a second displayport on a docking station I would guess it's the same issue. For reference i'm hit by the same issue due to using MST for daisy-chaining monitors. -- System Information: Debian Release: bookworm/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'oldstable-proposed-updates'), (500, 'oldstable-debug'), (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: armhf, arm64 Kernel: Linux 6.0.0-6-amd64 (SMP w/32 CPU threads; PREEMPT) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled
