Guys I’m trying to change my laptop build in screen resolution in kde plasma setting. But the screen went black after I changed the resolution.
I think it might be some drive issue so i downgrade my kernel but problem continue.
I also tried using gnome but same problem as kde.
I try to run "xrandr --verbose " and the output here :

and “xrandr --output eDP-1 --mode 1920x1200” output :
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 7 (RRSetScreenSize)
Serial number of failed request: 22
Current serial number in output stream: 23
And I have tried another distro using same version kde and kernel. it work just fine, no black screen issue.
This is manjaro’s bug I guess ?
