In Ubuntu (with Unity),
Alt launches the HUD. Fine. However, if you have a Windows in VirtualBox and you want to switch windows in the guest VM with
Alt+TAB, that damn HUD always appears in the host. How to disable it?
I found the solution here.
In short: top right corner, System settings… -> Keyboard -> Shortcuts tab -> Launchers. Assign a new key to “Key to show the HUD“, or disable it completely by pressing the Backspace.
I use Midnight Commander a lot and F9 in MC means: “go to the top menu bar“. However, Unity steals F9 and activates a widget layer. By default this layer is empty, so you only see that the screen greys out.
How to disable this shit?
ccsm“, find the Desktop section and untick “Widget Layer“. Done.
Alt key brings up the HUD. How to get rid of it?
Launch System Settings, then Keyboard -> Shortcuts -> Launchers. On Key to show the HUD, press
Backspace to disable it.
Under Gnome/Unity, you want to increase the number of virtual workspaces.
Start CompizConfig Settings Manager (
ccsm), then General -> General Options -> Desktop Size tab. Here adjust the horizontal and vertical virtual size.
