We want to set up a 3 screens with an onboard intel graphics adapter and an nvidia card.

Both cards are recognized in lspci

01:00.0 VGA compatible controller: NVIDIA Corporation GT218 [GeForce 210] (rev a2)
00:02.0 Display controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)

And bascially work: If I switch to the console, I see output on the Intel card, X is only running on the Nvidia card.

But when I type xrandr | grep conn I get only one connected port:

DVI-I-0 disconnected (normal left inverted right x axis y axis)
VGA-0 disconnected (normal left inverted right x axis y axis)
DVI-I-1 connected 1920x1200+0+0 (normal left inverted right x axis y axis) 518mm x 324mm
HDMI-0 disconnected (normal left inverted right x axis y axis)

I am on Ubuntu 12.10 (and XFCE) and installed the proprietary nvidia driver.

I was assuming that X maybe has a problem to autodetect both cards, so I thought the following xorg.conf could help:

Section "ServerLayout"
    Identifier     "Layout0"
    Screen      0  "Screen0"
    Screen      1  "Screen1"
    InputDevice    "Keyboard0" "CoreKeyboard"
    InputDevice    "Mouse0" "CorePointer"
EndSection

Section "Files"
EndSection

EndSection

EndSection

    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "GeForce 210"
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection


Section "Monitor"
    Identifier     "Monitor1"
    VendorName     "Unknown"
    ModelName      "Unknown"
    HorizSync       28.0 - 33.0
    VertRefresh     43.0 - 72.0
    Option         "DPMS"
EndSection

Section "Device"
    Identifier     "Device1"
    Driver         "intel"
    VendorName     "Intel"
    BoardName      "Internal Intel Graphics"
EndSection

Section "Screen"
    Identifier     "Screen1"
    Device         "Device1"
    Monitor        "Monitor1"
    DefaultDepth    24
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection

But it is still not working.

  • Is this generally possible to use two different drivers in X ?
  • Is it necessary to create an xorg.conf manually then? (because Ubuntu 12.10 normally works without the xorg.conf)
  • Are there any errors in my xorg.conf?

I'm trying to achieve exactly the same thing on Lucid version, and those questions makes me confused too. I can't makes ubuntu work with two drivers (ati(regular pci-e adapter)+nvidia(an msi on mother board integrated graphic adapter)). I can use one or other, but if i try to useboth of them X get confused somehow. I am able to deal with that and revert system to default state, after X goes wrong. So, after some time i concluded that maybe that integrated graphic adapter can work without manufacturer driver, perhaps some kind of genericdriver?? What do you think about this idea?

Regards,
