I want an executable script that changes screen configuration from 1 to 2 or from 2 to 1. I would need a boolean or a variable where the state is saved. It's that possible?

Otherwise, how can I check with xrandr if i'm using config 1 or 2?

This question came from our site for professional and enthusiast programmers.

You can probably ask xrandr what your current configuration is, and parse that output to decide.

However, failing that, to actually answer the question, the usual method for this is testing for the existence of a file:

if [ -f /tmp/screenstate1 ]; then
    rm /tmp/screenstate1
    echo "switching to state 2"
    touch /tmp/screenstate1
    echo "switching to state 1"
