See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** STEPS TO REPRODUCE 1. Select Wayland session on login screen 2. Enter password 3. Press log in OBSERVED RESULT Plasma crashes on startup EXPECTED RESULT Plasma starts up SOFTWARE/OS VERSIONS Qt Version: 5.15.3 Frameworks Version: 5.92.0 Operating System: Linux 5.19.0-41-generic x86_64 Windowing System: Wayland Distribution: Ubuntu 22.04.2 LTS DrKonqi: 5.24.5 [KCrashBackend] ADDITIONAL INFORMATION This is an Optimus laptop - integrated AMD GPU and dedicated GPU. The Nvidia GPU is operating in On-demand mode - the desktop should be running from the AMD gpu. When the system works (on X11 graphics server) the drivers manifest thus: ```bash user@laptop:~$ inxi -G Graphics: Device-1: NVIDIA TU117M [GeForce GTX 1650 Mobile / Max-Q] driver: nvidia v: 525.105.17 Device-2: AMD Renoir driver: amdgpu v: kernel Display: x11 server: X.Org v: 1.21.1.4 driver: X: loaded: amdgpu,ati,nvidia unloaded: fbdev,modesetting,nouveau,vesa gpu: amdgpu resolution: 1920x1080~144Hz OpenGL: renderer: RENOIR (renoir LLVM 15.0.6 DRM 3.47 5.19.0-41-generic) v: 4.6 Mesa 22.2.5 user@laptop:~$ __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia inxi -G Graphics: Device-1: NVIDIA TU117M [GeForce GTX 1650 Mobile / Max-Q] driver: nvidia v: 525.105.17 Device-2: AMD Renoir driver: amdgpu v: kernel Display: x11 server: X.Org v: 1.21.1.4 driver: X: loaded: amdgpu,ati,nvidia unloaded: fbdev,modesetting,nouveau,vesa gpu: amdgpu resolution: 1920x1080~144Hz OpenGL: renderer: NVIDIA GeForce GTX 1650/PCIe/SSE2 v: 4.6.0 NVIDIA 525.105.17 ``` I've since installed more ddebug files and will reproduce the crash with fewer missing line mappings. However, I've not been able to install the following debug symbol packages used by ksplashqml: The following packages have unmet dependencies. libcom-err2-dbgsym : Depends: libcom-err2 (= 1.46.5-2ubuntu1) but 1.46.5-2ubuntu1.1 is to be installed libdbus-1-3-dbgsym : Depends: libdbus-1-3 (= 1.12.20-2ubuntu4) but 1.12.20-2ubuntu4.1 is to be installed libexpat1-dbgsym : Depends: libexpat1 (= 2.4.7-1) but 2.4.7-1ubuntu0.2 is to be installed libgcc-s1-dbgsym : Depends: libgcc-s1 (= 12-20220319-1ubuntu1) but 12.1.0-2ubuntu1~22.04 is to be installed plasma-workspace-dbgsym : Depends: plasma-workspace (= 4:5.24.4-0ubuntu1) but 4:5.24.7-0ubuntu0.1 is to be installed E: Unable to correct problems, you have held broken packages. -- You are receiving this mail because: You are watching all bug changes.
