Hi,

My KDE randomly reboots. I've noticed it on Kubuntu and Manjaro KDE as well. Amusingly i've not had the issue when running Zorin Lite XFCE.
It tends to reboot when i'm not really doing anything intensive, like web browsing or reading a pdf for example.
There is no warning or error, the screen just goes blank and the system begins booting.
My specs are :-
OS: KDE neon User - Plasma 25th Anniversary Edition x86_64
Kernel: 5.11.0-43-generic
CPU: AMD Ryzen 5 1400 (8) @ 3.200GHz
GPU: AMD ATI Radeon RX 470/480/570/570X/580/580X/590
Memory: 3418MiB / 15896MiB

Is there a way to capture what is going on ? Or should i be looking somewhere specific in the logs ?
Any pointers gratefully received.
