[Dylan Smith <dylan.ah.smith@xxxxxxxxx>]

I have also had the same symptoms, I stop receiving keyboard events in X
after a VT switch, and I get the same errors in Xorg log.  I started
getting this bug when upgrading to karmic from jaunty, however, the live
cd environment or a clean install in a separate partition isn't able to
reproduce the bug.

The bug seems to depend on when gdm starts.  For instance, if I let gdm
start automatically like normal, then I will have the keyboard disabled
in X on a VT switch.  Logging out and logging back in will workaround
the problem, and then I can do as much VT switching as I want without
losing the keyboard.  I can also completely avoid the bug by delaying
gdm to start at rc.local, for instance by adding "initctl emit startdm"
to my /etc/rc.local script and adding to "and startdm" to the "start on"
upstart condition in /etc/init/gdm.conf.

The bug also only seems to affect my keyboard when plugged in as a PS/2
keyboard.  I have a PS/2 to USB adaptor that lets me plug in the
keyboard into a usb slot, and then I will not get this issue anymore.

I hope that helps.
