--- Comment #8 from Zamundaaa <[email protected]> --- Okay, after you unplugged the monitor, KWin does 1. a test with eDP-1 turned off, with ALLOW_MODESET (passes) 2. a test with eDP-1 turned off, without ALLOW_MODESET (fails) 3. a test with eDP-1 turned on, with ALLOW_MODESET (passes) 4. a test with eDP-1 turned on, without ALLOW_MODESET (fails) KWin only does tests with a display both off and on if the display is in power saving mode / dpms off, so that's definitely what's happening here. While the screen isn't turning on, please ssh into the system and get the output of > WAYLAND_DISPLAY=wayland-0 kscreen-doctor --dpms show Running > WAYLAND_DISPLAY=wayland-0 kscreen-doctor --dpms on afterwards *should* also turn the screen on again. Either way, there's a very good chance this is fixed in Plasma 6.6, as the dpms handling isn't per display anymore, and a lot more robust in general. -- You are receiving this mail because: You are watching all bug changes.
