dmesg from drm-nightly kernel
I uploaded a new dmesg dump from a run with kernel option "drm.debug=0x1e".
Summary:
I booted computer (in this case, two monitors attached, one DP and one HDMI)
with drm.debug=0x1e.
After boot, when reaching gdm login, DP-monitor goes black (similar as before).
Logging in to the computer via ssh, and, using xrandr, changing DP mode to
1920x1080, make DP-monitor start showing gdm login screen.
Kernel version used:
