Installed Ubuntu 22.04.4 LTS, and set a custom screen resolution by below command.
#sudo xrandr --newmode "1366x768" 85.25 1366 1440 1576 1784 768 771 781 798 -hsync +vsyn
#sudo xrandr --addmode eDP-1 "1366x768"
#sudo xrandr --output eDP-1 --mode "1366x768"

In before, in Ubuntu 20.04.3 LTS, use these commands to add a custom screen resolution,
no error.

or has method can fix it?
Thanks & Regards.
