Fix for sudden kde/wayland breakage on hybrid-gpu laptops

Hello to all

I have asus laptop with hybrid graphics (amd cpu + nvidia) and used the asusctl and rog control center for switching graphics and such.

I just updated the system and it froze for whatever reason. I tried rebooting several times but it just got stuck immediately after logging in through sddm and i had to do REISUB to restart. I tried several things and thanks to gpt I was able to fix this after an hour of diggin through logs and everything

Apparently, the newest update somehow broke wayland with nvidia drm modeset turned on. After turning it off it got back to working again for me, so I just wanted to post this if anyone would face the same issue after updating now

It is in /efi/loader/entries , you shoose the entry for your kernel and change the nvidia_drm.modeset to 0

Hi @Moshe_Yehudah

This is most likely the ddcutils bug that is going around lately.

TLDR: sudo downgrade ddcutils

You can find more details in the thread below.

Thanks for the heads up, I just updated the system and the issue reappered for me, hopefully th downgrade will work

Upd: yeah, downgrading this package resolved it for me, thanks for updating me on that, really appreciate that!
