Ich möchte herausfinden, welchen Desktop Manager ich ausführen möchte, und ich habe herausgefunden, dass es drei Umgebungsvariablen DESKTOP_SESSIONgibt XDG_SESSION_DESKTOP, und XDG_CURRENT_DESKTOPwelche mir dabei helfen könnten. Aber was genau ist der Unterschied zwischen diesen drei Variablen? Danke im Voraus.

I'm not sure what the official reasons are for having many different variables, most likely different window & display managers all do their own particular configurations.

But all of them look the same, so using any one should work...

Here's what Mint's XFCE has:

$ echo $DESKTOP_SESSION xfce $ echo $XDG_SESSION_DESKTOP xfce $ echo $XDG_CURRENT_DESKTOP XFCE

and also

$ echo $SESSION xfce $ echo $MDMSESSION xfce $ echo $GDMSESSION xfce

Or (from env):

XDG_MENU_PREFIX=xfce- UPSTART_JOB=startxfce4

Your best bet (if you've got wmctrl) may be this combined with grep/cut:

$ wmctrl -m Name: Xfwm4 Class: xfwm4 PID: 5449 Window manager's "showing the desktop" mode: N/A

You can also be using a different Window Manager and Display Manager, and some different distributions store data in different places, so confusion reigns supreme. See these very related Q's:
