Title:
  Light Display Manager fails to load

Status in xserver-xorg-video-openchrome package in Ubuntu:
  New

Bug description:
  I've got a Lubuntu 15 i686 installation with a VIA C7-D cpu. The
  system was purchased specifically to test the processor. Its got a 8GB
  SSD and 2GB of RAM, so its a lower end device.

  The machine appears to hang during boot. Some time around when text
  mode is supposed to end and the window manager should begin, the
  machine appears to freeze. I was able to install SSH through a
  recovery terminal, so I can peek at things remotely.

  It looks like Light Display Manager is failing:

      $ sudo systemctl --failed

        UNIT            LOAD   ACTIVE SUB    DESCRIPTION
      ● lightdm.service loaded failed failed Light Display Manager

      LOAD   = Reflects whether the unit definition was properly loaded.
      ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
      SUB    = The low-level unit activation state, values depend on unit type.

      1 loaded units listed. Pass --all to see loaded but inactive units, too.
      To show all installed unit files use 'systemctl list-unit-files'.

  It looks like the it could be related to the VIA P4M900 chipset:

      $ dmesg | egrep "(vga|agp)"
      [    0.190082] vgaarb: setting as boot device: PCI:0000:01:00.0
