Hi Peter.. 

Do you have any errors in your /var/log/Xorg.0.log???

Emne: Re: [Hybrid-graphics-linux] Optimus Solution found!!!! Using my Nvidia card in my Alienware M11X R2!!! 

Hi Luis, 

I've checked: 

lspci | grep VGA 
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated 
Graphics Controller (rev 18) 
01:00.0 VGA compatible controller: nVidia Corporation GT218 [GeForce 310M] 
(rev a2) 

cat /etc/X11/xorg.conf | grep PCI 
BusID "PCI:1:0:0" 
BusID "PCI:0:2:0" 

Section "Device" 
Identifier "Device1" 
Driver "nvidia" 
VendorName "NVIDIA Corporation" 
BusID "PCI:1:0:0" 
Option "IgnoreEDID" 
#Screen 0 
EndSection 

Section "Device" 
Identifier "Device0" 
Driver "intel" 
VendorName "onboard" 
BusID "PCI:0:2:0" 
#Screen 1 
EndSection 

I even stopped the display manager and reconfigured vgl_config, then rebooted. 
Should work in my opinion. Am I missing something?
