--- Comment #9 from alex.pan...@gmail.com --- I also tried tried to use ksreen-doctor, the same issue. kscreen-doctor output.HDMI-0.disable kscreen-doctor output.HDMI-0.enable output.HDMI-0.mode.2560x1440@60 output.HDMI-0.rotation.left output.HDMI-0.position.0,0 output.DP-2.position.1440,1120 It worked at first, but then the same black screen when I tried it later. Maybe it happens when there is a big delay between off/on, not immediately off and on. (probably the same for xrandr and the display settings, I think it worked like that some time ago) I also tried to just run kscreen-doctor output.HDMI-0.enable (after a long delay) without all other settings (position and rotation remain wrong). The screens did not turn black, but everything was somehow completely frozen, I could move the mouse cursor, but could not click anywhere, Alt-Tab etc., systemctl restart --user plasma-plasmashell.service had no effect (triggered it via a Talon voice command). It was probably just something about graphics, not the kernel hung up, because there was my alert sound when I triggered the voice command, and then I rebooted via reboot. -- You are receiving this mail because: You are watching all bug changes.
