[Launchpad Bug Tracker <1310633@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

I've tried upgrading and fresh installs of 14.04 several times. This was
done on a fresh install. Mouse freezes very quickly after login (< 1
minute or so). Trying ctrl+alt+F1 and does not switch screens and then
the keyboard becomes unresponsive (can still use ssh to connect). After
some of the upgrades, often also had excessive display flickering (and
mouse and keyboard unresponsiveness) and saw NVRM errors in kern.log.

Tail of current kern.log:
