Hi Santos and Peter.. 

I think you guys have the same problem.. 

Could you try the following: 

Add: 

Option "ConnectedMonitor" "CRT-0" 

to your nvidia device: 

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

Santos: You might need to change your BusID as well to BusID "PCI:1:0:0"... 

Please report back...

Hi all, 

After some tests ( i'm quite a nob), I have the same message 


reports: [VGL] ERROR: Could not open display :0.1. 

But I think PCI buses are correctly matched in the Xorg file..... 

I tried to launch vglrun glxgears 

CU,

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?
