[Launchpad Bug Tracker <1315073@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

Hardware: Cyberpower Z77 computer, including the following relevant
parts:

Motherboard: GIGABYTE GA-Z77-HD3 Intel Z77 Chipset 
Video Card: nVidia 760
Hard Drive: Samsung 128GB SSD, SATA3
Keyboard: Moshi Luna USB
Mouse: Razer USB gaming mouse

"Try Ubuntu 14.04 without installing" from USB key: No problems.
Install Ubuntu while in LiveCD environment: No problems (even browsed the web a bit).

On reboot, Ubuntu boots to LightDM, and that's as far as I can go.  The
keyboard doesn't respond, though I can successfully toggle F-Lock on and
off and the lights are on.  The mouse doesn't respond, and I see no
cursor.  There's a notification in the upper-right hand corner that
there are no connected networks.  I can't SSH in to get any logs.

WORKAROUND: Boot from LiveUSB; mount and chroot into install; download
and install Generic 3.14.1 MainLine kernel and reboot; everything is
fine.  But I don't think I have to tell anyone how not-ideal that is,
especially since chrooting these days involves three or four mount
--bind commands that are difficult for people to remember.

This has occurred on Ubuntu and Ubuntu Gnome spins.  This does not occur
with Fedora 20 (the only other distro I've tried on this hardware).
