Hi guys, I am having a problem that is driving me insane!
I have an Alienware M11x and installed the proprietary nvidia driver with optimus set using this manual: https://wiki.archlinux.org/index.php/NVIDIA_Optimus
I followed all the instructions on the manual strictly, edited the Xorg and .xinitrc files accordingly.
When gnome logs in there are two overlapping screens: VGA-0 and LVDS-0-1. VGA is set as primary and does not appears on the screen where as LVDS which is the correct one appears with the wring resolution, should be 1366x768.
To regain the single screen I can run xrandr --output VGA-0 --off.
The problem is, if I do this on the .xinitrc file the session doesn't starts at all.
Following is the output of some commands:
xrandr --listproviders:
Providers: number : 2
Provider 0: id: 0x282 cap: 0x1, Source Output crtcs: 2 outputs: 1 associated providers: 1 name:NVIDIA-0
Provider 1: id: 0x47 cap: 0x2, Sink Output crtcs: 2 outputs: 6 associated providers: 1 name:modesettingProbably relevant line from Xorg's log (where an additional 1024x768 screen is created):
