Recently I’ve been using Windows 8 as a virtual machine on top of Ubuntu 14.10.
One thing that bugs me is the Windows Logo Key, or known as Super Key in the *nix community. In Windows 8, we frequently need to press the key to go back and forth between the Desktop and the Start Screen. However, since the Windows 8 runs inside VMWare Player and the VMWare runs on top of Ubuntu, pressing the Super key will cause an annoying effect: Unity’s Keyboard Shortcut Overlay will show up above the VMWare window! Please see image below.
Ofcourse it can be closed. However, seeing the overlay covering VMWare everytime I press the key has became very disturbing. So it’s better to disable the feature. To do this, enter this command from terminal:
dconf write /org/compiz/profiles/unity/plugins/unityshell/shortcut-overlay false
Now the overlay won’t show up if I press the Super key from VMWare or if I hold Super key from other Ubuntu window. To turn it back on, just replace false with true:
dconf write /org/compiz/profiles/unity/plugins/unityshell/shortcut-overlay true
There’s a chance that you read someone suggesting you to use CCSM to do this task. I must warn you, using CCSM is not recommended since it may cause your system to become unstable. Happy virtualizing!
