SUMMARY After rebooting, one external display gets a signal but remains black. Panels are not moved, and the display is shown as enabled in Display Configuration. The affected screen is connected via Displayport through a USB-C dock STEPS TO REPRODUCE 1. Reboot (I had performed system updates and rebooted when they were done) OBSERVED RESULT One of two external monitors is black EXPECTED RESULT All displays show content SOFTWARE/OS VERSIONS Operating System: Solus 4.7 KDE Plasma Version: 6.4.80 KDE Frameworks Version: 6.16.0 Qt Version: 6.9.1 Kernel Version: 6.14.11-320.current (64-bit) Graphics Platform: Wayland Processors: 16 × 11th Gen Intel® Core™ i7-11800H @ 2.30GHz Memory: 64 GiB of RAM (62.5 GiB usable) Graphics Processor 1: Intel® UHD Graphics Graphics Processor 2: NVIDIA GeForce RTX 3060 Laptop GPU Laptop 3840 x 2400 @ 150% 2 external monitors 3440 x 1440 @100 % - connected via USB-C dock. One via Displayport one via HDMI ADDITIONAL INFORMATION Unlike bug 494262, this happens immediately after the system boots back up and does not require the displays to sleep or locking the screen This started happening in the last few days and has persisted through a few builds of git-master workspace Restarting plasmashell does not restore the display. To restore it once, I turned HDR off and on after having tried changing resolution The next time I turned HDR on and off and then changed the resolution and restored it
Is there anything visible on the display at all, if you move a window or the cursor to it?
(In reply to Zamundaaa from comment #1) > Is there anything visible on the display at all, if you move a window or the > cursor to it? I could move a window to it, but the display didn't show the window, or cursor. I haven't seen this in the last few weeks. The system now has KF 6.18.0, if that matters. I'll try to reproduce today and add a note if I can reproduce this or not.
I'm no longer able to reproduce this on git-master.
