Tool for easily creating custom Xorg resolutions?

Atemu@lemmy.ml to Linux@lemmy.ml – 16 points –

Creating custom resolutions is quite tedious. Surely I can't be the first person to desire a tool which just does it for me.

Enter x, y, rate and done. That's what I want. Quick feedback cycles. No running 3 commands manually specifying names or whatever; I don't care how it's called, I don't want to have to specify.

Does it exist? Preferably CLI or TUI but I could live with GUI.

I have a stupid little script for this:

#!/bin/sh

setres() {
  output=$1
  width=$2
  height=$3

  xrandr --output $output --brightness 0 --auto
  xrandr --delmode $output better
  xrandr --rmmode better

  xrandr --newmode better $(cvt $width $height | tail -n1 | cut -d'"' -f3)
  xrandr --addmode $output better
  xrandr --output $output --brightness 1 --mode better 
}

setres "$@"

Putting it in a function and the setres "$@" bit is superfluous here.

Eh, though you're right, it's a pattern I like a lot: define your "main" at the top, put all the supporting functions below, and call main at the end.

These days I've got a little bash task runner framework that I use for little scripts like this.

Nice script. What is the reason to toggle the brightness?

I didn't like the random blinking and glitchiness the screen did as it changed resolutions. Most OSes, if you notice, do a little fade out and in but I was too lazy to make it gradual.
