New issue 557 by joeyhe... at gmail.com: xmonad grabs keyboard and mouse on  
focus follows mouse, reproducibly
http://code.google.com/p/xmonad/issues/detail?id=557

What steps will reproduce the problem?
1. start xmonad on my new lenovo yoga 11s laptop with provided xmonad.hs
2. use laptop for a few hours (I was seeing this at least twice a day)

What is the expected output? What do you see instead?

This seems to occur when moving the mouse with focus follows mouse, and  
switching focus from one terminal to another (I have seen it using both  
xfce4-terminal and the sakura terminal). Xmonad seems to grab all keyboard  
and mouse events, and not release them, which results in no mouse  
movements, clicks, or keyboard activity doing anything in either xmonad or  
the applications on screen.

However, ctrl-alt-FN works, and if I use the console to kill all my  
terminals, this seems to convince xmonad to stop grabbing inputs.

I also tried using the console to start xev, and confirmed that it  
generally saw no X events at all. I think that one time xev reported a  
stream of X events, as if it were getting all the traffic I had generated  
while trying to use my locked desktop.

Also, at least twice, after a several minute delay xmonad has woken up on  
its own and dropped the grab. It then seemed to process all the keys I had  
pressed, which was disconcerting.

What version of the product are you using? On what operating system?

0.11 on Debian unstable with XFCE panel 4.10.1

Are you using an xmonad.hs?  Please attach it and the output of "xmonad
--recompile".

It's attached. Note that I have used xmonad for years without seeing this  
problem. I switched laptops, made some minor changes to my xmonad.hs and  
now it happens frequently enough to be a real productivity problem. On the  
other hand, if someone is looking to debug this somehow, I can probably  
reproduce it reliably enough to try whatever steps make sense to debug it.
