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

```
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.
