How to rotate extended monitor or individual monitor

[jpthank]

hi guys,

after i updated the nvidia grahic driver, I can't rotate the

monitor individually. e.g. i just want to rotate the extended monitor.


before the updation, i could go to system->preferences->monitors and rotate each screen separately. no problem.


so, i checked /etc/X11/xorg.conf

and i added Option "RandRRotation" "On"

now, the problem is, when i try to rotate, both the displayers will rotate(2 monitors will rotate)

which i dont want. any ideas? need ur help please.

by the way, when i type: xrandr in the terminal,

it shows:

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1600 x 1200, current 2966 x 1200, maximum 2966 x 1200
default connected 2966x1200+0+0 (normal left inverted right) 0mm x 0mm
2966x1200 50.0* 51.0
1600x1200 51.0

it seems there is a problem with the graphic driver?

here is what shows when type cat /etc/X11/xorg.conf
