Odd. Do you use an alternative shell, such as fish ? Also, what happens if you run which xrandr, for instance ?

[tuxayo]

what happens if you run which xrandr, for instance ?

/t/gaming-flightcheck ❯❯❯ which xrandr /usr/bin/xrandr

indeed!

I use Zsh with the Prezto config https://github.com/sorin-ionescu/prezto (Prezto shouldn't matter I guess)

[Askannz]

Is the bash executable in your $PATH ? Try the command which bash.

[tuxayo]

Yes it is.

~ ❯❯❯ which bash
/bin/bash

Tested with latest version (67cdf8757ad7af8fd00cb64346ac6d6ff98270be) and bash -c
