Hello,

I am using a cluster of machines running on Ubuntu 10.04 LTS which are supposed to be homogeneous, but apparently they are not. In particular, I am configuring the X server on these machines, and I pushed a /etc/X11/XF86Config that includes the following section:

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BusID          "PCI:5:0:0"
EndSection

The problem is that the BusID of the graphic card is PCI:5:0:0 for some machines, and PCI:3:0:0 for others. Is there a way that the X server automatically detects the appropriate Device (based on the name for instance)?

Thanks,
