det jag provat mest är
cvt 3440 1440 80
Output: Modeline "3440x1440_80.00" 571.75 3440 3712 4088 4736 1440 1443 1453 1510 -hsync +vsync
sen kör jag: xrandr --newmode "3440x1440_80.00" 571.75 3440 3712 4088 4736 1440 1443 1453 1510 -hsync +vsync
och efter det xrandr --addmode DP-4 "3440x1440_80.00"
och det är där problemet börjar:
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 18 (RRAddOutputMode)
Serial number of failed request: 47
Current serial number in output stream: 48

jag vet att den kan vara utdaterad, men jag hittar fan inget annat vettigt
