Public bug reported:
Ubuntu 14.04
xserver-xorg: 1:7.7+1ubuntu8.1
I don't know how to trigger this bug, but I have seen it now more than
ten times.
"Suddenly" = I can't figure pattern how this triggers. Sometimes it
happens when computer just idles
'stops working normally' = tab-key alone doesn't do anything.

When tab-key is working normally, xev reports:

And behaviour is like xev reports: tab pressed alone doesn't do anything, but
with any modifier it works as expected:
alt+tab = change window
shift+tab = previous element (e.g. fields in browser)
ctrl+tab = change tab (e.g. in firefox)
-----
I have ~/.Xmodmap and it contains line:
keycode 23 = Tab ISO_Left_Tab Tab ISO_Left_Tab Tab ISO_Left_Tab
Running xmodmap ~/.Xmodmap will not fix.
---
Attaching new usb-keyboard doesn't help.
---
Reboot helps.
---
Changing to virtual terminal -> tab is working. But after returning to xorg,
tab is still broken.
