This seems like a problem beneath us in the stack, and having to do with buggy graphics drivers. Can you please report this to the Mesa developers? See https://docs.mesa3d.org/bugs.html |
Created attachment 188200 [details] gdb log session when I attempted to debug SUMMARY Kde plasma (wayland only tested) will not start with linux kernel 6.18 or above. it will start and run fine with 6.17 or earlier. This only happens with my intel B580 Graphics Card. This does not happen with integrated Ryzen 9000 or iris graphics 80EU. This only affects KDE (sway, xfce, niri, hyprland work without issue). Down grading Kernel to 6.17.9.arch1-1 will fix this (not much of a fix). Versions 6.18.2.arch2-1 and 6.18.3.arch1-1 cause this. I do not have older kernel versions currently to test with STEPS TO REPRODUCE 1. upgrade kernel to 6.18 (or higher) 2. attempt to start kde plasma (weather from sddm or tty[startplasma-wayland]) 3. nothing happens after successful login, tty session freezes OBSERVED RESULT System locks up, this includes switching to a seperate tty on the same screen. HOWEVER, ssh works in this state so the system can be observed and recovered. restarting sddm will unfreeze the system if plasma was started from sddm EXPECTED RESULT KDE plasma to load normally SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux KDE Plasma Version: 6.5.4 KDE Frameworks Version: 6.21.0 Qt Version: 6.10.1 ADDITIONAL INFORMATION running startplasma-wayland with gdb showed my nothing
