--- Comment #18 from Patrick Silva <bugsefor...@gmx.com> --- This problem happened 5 times on my Arch Linux since my previous comment here, once on X11 and 4 times on Wayland (3 today after logout from X11 session). On X11, my monitor spontaneously enters in power saving mode again when the timeout configured in Energy Saving KCM is reached. However, on Wayland the monitor does not enter in power saving mode again until some keyboard key is pressed (I pressed CTRL today) or mouse is moved. I do not know if the bug is related to usb mouse yet. This bug will potentially damage many monitors if it is not fixed before Wayland session of Plasma becoming popular. SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.22.0 KDE Frameworks Version: 5.83.0 Qt Version: 5.15.2 Graphics Platform: Wayland -- You are receiving this mail because: You are the assignee for the bug.
