As far as I read there is no way to disable a pci slot. You can only force something to use a certain one. Check in your /var/log/Xorg.0.log, there should be a line like this one (with a different chip, I'm on another computer at the moment):
(II) Nov 24 09:47:43 NVIDIA(0): NVIDIA GPU GeForce 8400M GS (G86M) at PCI:1:0:0 (GPU-0) That line indicates that the nvidia driver found a nvidia chip at the given pci slot. If you have that line, I suppose your asterix above doesn't mean anything too relevant to our problem... -- nvidia propietary driver fails to load X with geforce 310M https://bugs.launchpad.net/bugs/643895 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
