Poked at the system settings, display settings, and changed screen rotation setting to 180. Immediately after rotation setting became read only, and then after 30 seconds it crashed.
After reboot i cant'go to system setting any more, it just says to me that it cant open display settings and hangs.
NVRAM reset (options+cmd+R+P) does not reset screen rotation setting, only everything else.
So. How to do rotate display back to default? Command line options anyone?
