Comment 224 for bug 195982

I have no problem with Shift or Alt, but with Ctrl, everytime when I leave the vmware player on natty (Kubuntu, no Unity or the like here).
(I am using the Neo keyboard layout, so I have no CapsLock key to test.)

Unfortunately, this bugreport seems to be a big mess:
* People having problems with different keys,
* with or without(?) varying(?) virtualization solutions,
* sometimes mentioning new HID hardware (applies to me, too [1]),
* sometimes mentioning graphics drivers (closed-source NVidia for me, too),
* with varying software and kernel versions,
* and with different proposed workarounds (calling 'setxkbmap' being the most efficient one AFAICS).

And for me, I can only say that I did not have this problem in the past, but I am not sure which of the many things that changed in the meantime caused this:
* upgrading from Maverick to Natty
* installing the new keyboard [1]
* performing daily Ubuntu software updates
* updating VMWare player
* /not/ using Unity ;-) but KDE (half-jokingly, after all vmware-player has an "Enter Unity" menu entry)
* using Ctrl-Alt to release the kbd grab

The latter seems to be the most likely to me; in the past, I just moved the mouse to the top to reveal and focus the menubar and then used Ctrl-F2 to change the virtual desktop, but that does not work anymore. So I had to learn about Ctrl-Alt, but now I have the problem with Ctrl stopping to work. (It's always Ctrl, but never Alt, independent of the order in which I press or release the two.)
