Can you test with latest kernel (drm-tip)? I spot DP-MST, so this is likely a dupe of 96781. *** This bug has been marked as a duplicate of bug 96781 *** Hm the oops I meant related to dp-mst is not the same one as the linked bug, but should probably have the same root cause as 95165. *** This bug has been marked as a duplicate of bug 95165 *** Danien (reporter), agree resolving duplicate? If so, please close. Closing |

Created attachment 127702 [details] xrandr --verbose I see a black screen and a frozen machine rather often, especially in the context of (un)plugging an external screen and VT switches. This one happened when switching from VT2 with an X server to VT1, where a (non-X) login prompt should have appeared. The external screen was not detected anymore: its power had been turned off (and on again); it showed up in "xrandr -q", but was not receiving a signal anymore, and "xrandr -s 0" did not help. I wanted to see if it would work on another VT (console and Xorg), but then the screen turned black, and I had to press the power button 8 seconds to turn the laptop off. Then the screen turned fully black - it appeared to have some dark/blackish backlight still before.
