Check which window manager is running on Linux

In the terminal type env to see all environment variables. Some of them are:
XDG_CURRENT_DESKTOP - Tells you what Windows Manager you are using
GDMSESSION - Tells you what option you selected from the lightdm greeter to login.
To use them, go to the terminal and type:
(Will output for example 'unity' if you are using Unity)
(Will output for example 'ubuntu' if you selected ubuntu in the login or 'ubuntu-2d' if you selected that one in the login.)
You have others if you look closer at the output of env like DESKTOP_SESSION and COMPIZ_CONFIG_PROFILE
