I think i may have a similar problem.
From time to time my system will just completely lock up and require a reset. Its been happening one to two times a day
I'm not sure if its related to the Gnome 40 upgrade or from the fact that i started to use Blender (Installed from the Solus Repo) around the same time.
There is no definite set of steps i can find to reproduce it. Once it locked up while watching a youtube video (Using firefox). A few times i would turn my screen off and walk away. When i returned the system would be locked up.
Yesterday it locked up around the time I plugged in a Wacom tablet. But doing it again now i can plug and unplug it fine.
I am trying to narrow it down by not using Blender today and seeing if it still locks up.
I didn't see anything in the log but my log searching skills are also quite limited. If anyone has a good useful command for getting logs then let me know. I'll see if anything more useful pops up if I do get another lock.
I'm using Solus Budgie.
Specs: Ryzen 5 1500X
16GB DDR4 2933MHz ram
Vega 64 Nitro+ (Stock settings)
Edit: Forgot to add: My system is fully up to date as of last Friday. I also checked for broken packages but it was all clear.
