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.
