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 Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
