RESOLUTIONMAKER is a script which makes a custom resolution. it can be handy if you have some problematic monitor, etc. If resolution is acceptable, it can add to thr startup. In antiX on the bottom of $HOME/.desktop-session/startup

If script is installed as a program, custom resolution file comes to $HOME folder. If running as plain script, custom resolution comes directory, where the script has launched.

An example:

xdg-open $HOME/.desktop-session/startup

… add custom resolution without #/bin/bash

xrandr --newmode "1552x1100_60.00" 142.25 1552 1656 1816 2080 1100 1103 1113 1141
xrandr --addmode VGA1 "1552x1100_60.00"
xrandr -s 1552x1100
