screen color distortion after xrandr

[Felmon Davis <moelmoel2714@gmail.com>]

greets!

I was trying to get a second monitor (a tv) to work using xrandr. I 
noticed that the screen on the laptop would suffer severe, almost 
'psychedelic', effects if I hit a certain setting.

unfortunately I don't recall the setting but the ill effect was 
consistent and rendered the display nearly unreadable. and the only 
solution was to end the session.

then by accident I hit the 'save this configuration' key and now the 
setting is permanent.

btw I created a second user and it doesn't suffer from the problem.

I cannot find a way to restore the proper display setting. there's no 
configuration file I can find for xrandr.

it's an Asus Zenbook with Intel HD graphics.

I am considering shifting to the second user and grappling with the 
UID and GID changes. I ultimately want to get back to using the 
original username.

surely there is a simpler solution. perhaps purge xrandr?

thank you.
