How to set default display orientation in Ubuntu?

Question

ubuntu

After the next update, the default settings of the function keys in ubunt flew off. And now, thanks to playful pens, I pressed something (namely Fn + F4, but what hangs on it now - I don’t know), and the image turned 90 degrees. counterclock-wise.
It would seem that there is. xrandr -o normal
But after a reboot, the desktop was again on the left side :(
Ubuntu 14.04, cinnamon
Where can I set the default settings?

Answer 1

Isn't there a monitor control panel O_o?
You can also edit/delete ~/.config/monitors.xml (this is in Unity, not sure how it is in Cinnamon)

Answer 2

you can hang the given script in autoload until you figure out the problem
