It’s true that I am configuring many things at the same time. Thank you very much for these inputs, too, about wayland and qt and everything 
I now think it is my Nvidia card that caused the crash and not Wacom., the reason being How to fix fedora 37 freezing
and mind you i don’t want to install nvidia drivers… I have ethical/moral disagreement with proprietary GPU and it is very awesome that Fedora doesn’t try to supplement that by default. but a card is in my computer.
So! I checked with the command from the discussion journalctl -b -1 --priority=3 after my brief brushwork attempt caused the computer to completely freeze and compel me to hard shut it down…
**(first hard shut down of today)**

this was after using Krita for about a minute, and I didn’t press tablet buttons that time. I put faith that installing updates from reinstalling the OS and using my wacom intuos tablet immediately, without any rebooting, would work. Just to see! But it didn’t 
I am lucky that it didn’t kill my internet connection and display, like it did yesterday, the crash + hard shut down I started this thread for…
Just some minutes ago I had a similar problem when I opened the Falkon browser and tried to make a request into Duckduckgo. Complete freezing, and had to hard shut down. I input the journalctl command again when I booted back up, and got a much shorter error log, with a setfont issue, which it had in the earlier error log
(second hard shut down of today)

i won’t try installing nvidia drivers just yet, but I will try soon-ish after I wait for any ideas! (like… a way to disable the Nvidia card and try to rely on the processor instead…? I might have to buy a new processor… but is there a way? Just a note, this is a computer and not a laptop. It was a new computer in 2010 and it was used by my family for playing Skyrim and Starcraft etc when we were young~but I’m just interested in art and ethics as an adult~) Thank you.
