Unable to login after changing display scale.

[Przemys?aw Wojtkun]

At the login screen press Ctrl+Alt+F2.  This should give you a non-gui login.  If you can log in here, it should allow you to enter any cli commands you may have available to undo the change.

Entering

Code:

startx

Will try to start the GUI.

I've tried restarting the GUI using startx, it just fails. At the end of Xorg.1.log there is

Code:

Segmentation fault at address 0x0
Fatal server error:
Caught signal 11 (Segmentation fault). Server aborting

I can't use xrandr command if xorg server is not running right? How can I change the scaling setting then?
