# xrandr -q | grep " connected"

# bug report:
# there is sometimes a toggle. severel versions of this scripts run sometimes.
# for minutes i have tested this script with "1" and then with with "0.2".
# during this video it jumps back to "1" ?? whey? lets try kill autokey and start it again

# you could see. it dont toggle. if autokey is off. brightness stays. not toggle.
# ups. noooo. i doesent !!!!!!. my system automatically set brightness to 1???? whey??
# so i need a loop that every 10 seconds set the brithness again :( hmmmm. thats not the best solution.
