Bug#681796: Hitting this without suspend

[Ben McCann <bn.mccann@gmail.com>]

I am also hitting this bug but I don't have to suspend. It happens maybe 
once a week while using Xorg. The X server dies and then Kdm (?) puts up 
a new login screen. I can log back in and then resume work.

Can't pin it on any one action although it appears to be related to 
using the touchpad on my Acer 1810tz laptop. I'm running Ubuntu 12.04 
fully up to date.

LMK how I can help track it down. I could attach gdb to the Xorg server 
on one the TTYs but I don't know if I could swap over to it 
(ctrl-alt-F1) after Xorg crashes and is sitting in gdb.
