Also, is this a regression?  Did this issue start happening after an
update/upgrade?  Was there a prior kernel version where you were not
having this particular problem?

Title:
  DRM for Via GPUs is missing

Status in linux package in Ubuntu:
  Incomplete
Status in linux source package in Zesty:
  Incomplete

Bug description:
  17.04 Beta 2 (Zesty Zapus) amd64

  Via PM800 chipset (S3 UniChrome Pro)

  Xorg.0.log:
  [    25.194] (EE) CHROME(0): [drm] Failed to open DRM device for 
pci:0000:01:00.0: No such file or directory
  …
  [    25.469] (EE) AIGLX: reverting to software rendering

  ls: cannot access '/dev/dri/card0': No such file or directory

  ls: cannot access

file or directory

  No DRM so no acceleration with Openchrome.  This will make me and
  other Ubuntu 17.04 users with Via hardware sad (I'm guessing there's
  at least five of us).  Makes for an annoying Ubuntu experience when
  browsing the web at nearly slide-show speeds while trying to find the
  correct drivers for our Nvidia and AMD cards.

  Not sure if it matters for the DRM module but Openchrome 0.6 has been
  released:  https://lists.freedesktop.org/archives/openchrome-
  devel/2017-March/003232.html
