Public bug reported:
Apologies if I shouldn't file a bug on this -- I've seen that it is
already fixed in (at least) the most recent Utopic kernel. But I can't
actually use that kernel either, due to a regression (I guess that will
be a separate report). Consider this a suggestion to backport the fix
for this to Trusty.
When booting the current Trusty kernel, there is no video on the
touchscreen. HDMI output works, and even without HDMI connected X is
running fine (as evidenced by connecting through x11vnc). And either
alternative output method shows that the touchscreen is working fine as
an INPUT device. But no picture.
Attaching two udev logs, one from booting 3.13.0-32, the other from
3.16.0-6. You can see that in the 3.16 log, quite a few more devices
under /devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/INT33C3:00/ are
discovered compared to the 3.13 -- I'm assuming one of those is the
video, since that's where the touchscreen-as-input lives.
