Public bug reported:

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

ls /lib/modules/4.10.0-15-generic/kernel/drivers/gpu/drm/via/via.ko
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
