With multiple graphics adapters, may choose the one the user doesn't want

[Dhonn]

I have a computer that has onboard video. When a video card is installed it disables the onboard video card making it inactive. When xserver-xorg is installed it detects both my graphics cards but chooses the onboard gfx card driver. Because of that desktop then never loads. I have to manually change the driver setting.

Section "Device"
        Identifier "Silicon Integrated Systems (SiS) 661FX/M661FX/M661MX/741/M741/760/M760 PCI/AGP"
        Driver "sis"
        BusID "PCI:1:0:0"
EndSection

I must change sis to nv or nvidia.

If theres any more info you need let me know. This bug is very critical to installation.

I can confirm this bug. I'm running an eMachines T3990 which has onboard Intel i810 (I think 845, but it doesn't really matter) graphics and I installed a PCI nVidia card and set the BIOS to put the video through the PCI card, but Ubuntu still sets up the driver for the i810 onboard video.

I've reported this bug in SUSE as well: https://bugzilla.novell.com/show_bug.cgi?id=146518

I recommend disabling the onboard video in BIOS setup if you are not using it; this will ensure that the correct device is used

The onboard shared video is completely disabled my motherboard automatically does it when I install an agp gfx card. Its a shared video card and no memory is being a located to it.

All other distributions gets it right though and chooses the right card, NV.
