Hi,

I've managed to get optimus works on my PC with nvidia property
driver. But I got into an issue when trying to extend my screen to an
external monitor by using Xrandr.
There is no signal in the external monitor but the screen do extended,
as mouse and window can be moved outside the visiable screen.

There are 2 output connected, LVDS-0 & VGA-0.
The xrandr command used:
# xrandr --output VGA-0 --pos 1366x0 --auto
And also tried (doesn't work),
# xrandr --output VGA-0 --auto --left-of LVDS-0

This one works but both monitors showing with the screen,
# xrandr --output VGA-0 --auto --same-as LVDS-0

Any suggestion please?


Since you're using the proprietary driver, have you tried using the nvidia-settings configuration program to set up the second monitor?


 
Thanks,
