Bottom line: If someone wants virtual desktops in Mint, in under five minutes, what do they do?
Virtual desktops: Managing (switching between) multiple 'screens/desktops' that contain your program windows. Native to Linux.
After approximately two hours of research, I installed Compiz, which turned out to be incompatible with Mint because the Mint 'Desktop Environment' is 'Cinnamon', which is based on 'Gnome'.
This environment uses Muffin as a 'windows manager', which is based on Compiz.. meaning that support for fully qualified virtual desktops should be native.
I.e. it's already there. I can have multiple desktops right now.
New question: How?
I have googled extensively, and read the manual. No dice.
Update Edit: A few more hours of googling has taught me that 'desktops' are called 'workspaces' in Linux.
You'll never find mention in the manual, and there is presently no Wiki for Mint.
If you want to have virtual desktops in less than five minutes, do this:
Hold CTRL and press the right or left arrow to switch desktops.
Now, what remains for me is learning how to manage the 'desktop manager', however there appears to be no manual.
New bottom line question: I don't want to spend three hours to learn something that should take three minutes. Google didn't help, the manual was too basic, there's no wiki... Where/how does one quickly learn how to use Mint?
