[xubuntu-users] 20.04 install issue: Monitor resolution bad

[Elbert LaGrew]

I made this simple file and execute it.  The options show un in arandr

#/bin/bash!
xrandr  --newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083
1088 1120 -hsync +vsync
xrandr  --newmode "1920x1200_60.00"  173.00  1920 2048 2248 2576  1200 1080
1083 1088 1120 -hsync +vsync
sleep 1
xrandr --addmode VGA-0 1920x1080_60.00
xrandr --addmode  VGA-0 1920x1200_60.00
