So, now you could install the system with DP-DP? And on the running system, try to switch to DP-HDMI. Do you see the same problem? When you reconnect back to DP-DP, does it recover again?
If all yes, please try like the following: - Boot with DP-DP, go up to GUI desktop - Enable the debugging of drm, run below as root echo 0x1e > /sys/module/drm/parameters/debug - Re-connect to DP-HDMI, and you'll see a buggy screen - Re-connect back to DP-DP, screen recovered - Save the output "dmesg" command, and attach the output to Bugzilla
Did as as requested, had video output for both DP-DP and DP-HDMI. output of dmesg is attached. -- You are receiving this mail because: You are on the CC list for the bug.
