--- Comment #33 from Nicole Schoebel <schoebel220...@nschoebel.de> --- I just made an interesting observation. A couple of days ago I added a second monitor to my system. Since then the bug had disappeared. I would always see the lock screen as intended. Today I checked what happens when I remove the second monitor again. I unplugged the second monitor from the computer, changed “/etc/X11/xorg.conf.d/10-monitor.conf” back to what it was before, and rebooted. The bug was back. I would see a black lock screen with the exception of a visible mouse cursor. I then plugged the (second) monitor cable back into the computer, but did NOT connect the other end to the monitor yet. Bug still there. I then connected the other end of the cable to the monitor, and - without having to reboot (!) - the lock screen would then work as intended. The monitor was connected to power, but in standby at that point. When I turned it completely on nothing was visible, it wasn’t even getting a signal. “xrandr -q” was showing the monitor as connected though. I then unplugged the monitor cable from the computer again. The lock screen would still work as intended. So, to sum it up: As long as I connect a second monitor at any time after a reboot, the lock screen will work as intended until the next reboot. The monitor does NOT have to stay connected. It just had to be there at some point. For information: My primary monitor is connected via DisplayPort. The second one is connected via HDMI. -- You are receiving this mail because: You are watching all bug changes.
