SUMMARY When starting KDE Plasma 6, my second monitor is not enabled by default. Going to the settings menu and trying to turn on my monitor causes the entire system to freeze to the point that I cannot even use the Ctrl+Alt+F2 command to bring up a shell to kill Plasma and restart it. This only started happening after upgrading to Plasma 6.0.2 from the Arch repos. STEPS TO REPRODUCE 1. Go to System Settings, then Display Configuration 2. Click on Dell Inc. DELL M991 on menu, then click the checkmark to enable it 3. Click "Apply" OBSERVED RESULT System becomes entirely unresponsive, any sound that was playing loops over and over, I can hear the second monitor turning on but nothing displays on it. I have no choice but to hard reset the system when it happens. EXPECTED RESULT The second monitor comes on and I can move applications over to it. SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.0.2 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.2 Kernel Version: 6.7.9-zen1-1-zen (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 5800X 8-Core Processor Memory: 31.3 GiB of RAM Graphics Processor: AMD Radeon RX 6800 XT Product Name: X570 Steel Legend WiFi ax ADDITIONAL INFORMATION The second monitor actually works and displays the login screen when logging on on SDDM, however the monitor gets disabled when logging into Plasma.
Please check your journal from when the hang happened > journalctl --boot -1 If audio is looping for you, it'll most likely contain a backtrace for some kernel crash
Created attachment 167207 [details] Output of "journalctl --boot -1"
I've attached the output of the command piped into a text file.
Was that on the boot after you triggered the hang? Other than some benign warnings, there's nothing suspicious in the log
(In reply to Zamundaaa from comment #4) > Was that on the boot after you triggered the hang? Other than some benign > warnings, there's nothing suspicious in the log I triggered it again, rebooted, then ran the command.
https://pst.innomi.net/paste/3kd9k94s3wbfoeaqjacdzq6g Had another crash that may or may not be related after using the system for a few minutes after it was in sleep mode overnight. The screen went black for a second, then it came back for ~10 seconds with some areas looking garbled, then it went black again and the system was unresponsive, forcing me to reboot. These logs seem to contain more useful data.
Just replying to this saying that the bug seems to have gone away, I haven't had any issues with crashing using my second monitor anymore.
