This is getting really annoying

Have you tried an other Kernel? And can you explain a little more the problem?

4

Seems related to my problem, I’m using gnome with nvidia, but the logs are the same on the coredumps, my guess is the glibc built for v3, but idk anything.

Edit: changed the glibc to the non v3 and it freezed too, so idk.

5

Interesting I installed GNOME and no longer seeing the issue

6

anyone have any ideas, GNOME is decent but I have noticed my game doesnt notice i have a HDR monitor, while plasma does

7

Still happening to me, it seems to happen when my screen is turned off.

Think I got it tackled.

Added POWERDEVIL_NO_DDCUTIL=1 to /etc/enviroment and switched back to regular kernel from the rc.

cat /etc/environment                                                                                                                                                                               ─╯

Open the terminal: Run sudo nano /etc/environment

Copy: POWERDEVIL_NO_DDCUTIL=1

In the terminal use the arrow key to go down to the next line after # right click on the terminal and select paste. Press Ctrl + X and Y and Enter. Restart the PC and see if it fix it.
