I have installed 17.10 with Unity...
All works fine except the shortcuts I used to change between workspaces:
I had arranged a 2x2 grid
and with Ctrl+Alt+CursorDown I could go to the bottom,
and with Ctrl+Alt+CursorUp could go to the upper...
Now it is not working. Only with Super+PageUp or Super+PageDown...
Any idea how to retrieve this functionality?
To the sides it works ok...
