How can I determine which compositor is currently being used when multiple desktops have been installed such as LXDE and XFCE. Compiz is also installed.

Is there a code that will show which installed compositing manager being used?


There is no direct command to get your current compositing manager. To do that, we need to make a list of them and check in the current processes. I made a script for this. Here it goes:


COMPOSITORS=('awesome' 'beryl' 'blackbox' 'compiz' 'dwm' 'enlightenment' 'fluxbox' 'fvwm' 'i3' 'icewm' 'kwin' 'metacity' 'musca' 'openbox' 'pekwm' 'ratpoison' 'scrotwm' 'wmaker' 'wmfs' 'wmii' 'xfwm4' 'xmonad')

for i in `ps -u $USER -o comm`; do
    for c in ${COMPOSITORS[@]}; do
        if [ "$i" == "$c" ]; then
            echo "Your compositor is $i"

Open your editor, paste the code above and save it with the name check-compositor.sh. Then open the terminal and execute $ sh path/to/your/file/check-compositor.sh That should show your current compositor manager. You can add more compositing managers to the list if you wish, but I think that's pretty much all of them.

  • You could add xcompmgr, see here, since OP is interested in LXDE. Also, I'm not sure about including Openbox. To my mind, it's a window manager. (I don't use compositing myself and am not familiar with the other names in the list.) – user25656 Apr 4 '13 at 3:08
  • @Ringtail, what do you have in autostart? – user25656 Apr 4 '13 at 3:09
  • @vasa1 nothing in .config/autostart for a comp-manager – Ringtail Apr 4 '13 at 3:26
  • do you have something like ~/.config/lxsession/Lubuntu/autostart? I know you haven't said you're using Lubuntu (or ~/.config/lxsession/LXDE/autostart)? – user25656 Apr 4 '13 at 3:38
