This file includes stdout as well as stderr from running "gpu-manager
--dry-run" without the workaround.

"Error : Failed to open /dev/dri" message appears on stderr. Last card
is set to 1 and number of cards is set to 3. The first card (00:02.0) is
the integrated i915 gpu. The second is a 290x card (01:00.0) and the
third is the only one that is not using the pci-sub module (02:00.0).

With fake_lspci file that only includes the card intended to be used,
the number of cards is set to 1 and the last cards number is set to 3.

Title:
  gpu-manager tries to use pci-stub module as a vga driver

Status in ubuntu-drivers-common package in Ubuntu:
  Triaged

Bug description:
  There is two AMD gpu:s installed in my computer. The first one uses
  the fglrx module and is the one that is intended to be used for the
  linux desktop. The second is intended for gpu passthrough and owned by
  pci-stub.

  gpu-manager makes the assumption that a card shall be used based on
  vendor/device id and if the fglrx module is loaded. That is not
  sufficient in this case. I have not verified if the same applies to
  xen-pciback but it seems likely.

  My workaround has been to use the fake lspci file option and a
  manually created xorg.conf. Everything worked fine before I changed
  one of the cards to use the pci-stub module. The result before use of
  fake_lspci was a permanently blank screen.
