Not sure if this is a powerdevil issue. But since I’ve updated plasma to 6.5.3 I’ve had a DDC/CI brightness issue for my monitor. Before the update it worked fine. Restarting the service briefly allows me to change the brightness of the monitor, but the option goes away as soon as I close the brightness tab, after doing so plasmashell sometimes crashes.

this is the output of systemctl --user status plasma-powerdevil.service
Can anyone confirm this? Or is this an nvidia issue again, i’m using the latest nvidia-open 580.105.08-4driver
No idea how else i can troubleshoot this.
