i used to make custom res on windows.. my hdmi monitor is 144hz and my dp monitor is 180hz.
I'm not sure I can help here, sorry
video to create custom resolution or refresh rate:https://www.youtube.com/watch?v=pkzrQqT_lFI
In this video I will show you How to set a Custom Screen Resolution in Ubuntu Linux.
Commands used in the video (watch the video as some commands could be different in your case):
xrandr
cvt 1920 1080
sudo xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1088 1120 -hsync +vsync
sudo xrandr --addmode Virtual1 "1920x1080_60....
this works on X11 graphics platform, which you are on
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: 41
Current serial number in output stream: 42
Why do you need a custom resolution? Are the supported modes of your display not properly registered?
