Rajeesh K V <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #4 from Rajeesh K V <[email protected]> --- I hit the same problem with plasma 6.5.3, Intel Alder Lake UHD 770 graphics, connected via displayport to a Samsung Galaxy Viewfinity S8 4K monitor, after enabling HDR. The screen can be recovered by turning off HDR (and then reverting the config) also works, until system goes to sleep next time. In the system log, I could see the following: ``` Nov 27 10:09:45 brussels kscreenlocker_greet[16677]: Failed to write to the pipe: Bad file descriptor.
