Hello,

I run Lubuntu 15.10 on my laptop and I've installed many desktop environments (I'm an indecisive person, lol) including lxde (default) gnome, gnome-flashback, ubuntu-desktop, ubuntu-studio, xfce, openbox, fluxbox, and MATE.

I've since decided to drop all of it and revert to good ole' fluxbox. When I started using fluxbox I noticed that sometimes certain things (like launching nautilus or swapping workspaces) cause the background to change to the one set by lxde, and of course, the right-clickable menu gets replaced by desktop icons.

I've uninstalled all the extra gui's via and but I'm still seeing the same issue.

Basically, it's like certain things sometimes trigger (not all the time, it's not even consistent) parts of lxde to pop out into fluxbox's space.

Any ideas?

Regards,

I dont use any of the *buntu's, but try looking in your .config folder. Maybe something like "~/.config/lxsession/Lubuntu/", possibly rename or move to another location suspect folders to try it. If I remember correctly LXDE used pcmanfm which has the capability of managing wallpaper and such, so look at that too. Hope this helps some.

You can have multiple desktops/window managers installed and they should not interfere with each other.

Nautilus will change the background on launch because it's also a background manager by default. You can stop that behavior by launching Nautilus with (or changing your Fluxbox menu item to)

which certain things are doing that?
find that out, and you are 9/10 of the way to a solution.

Did you reboot when you switched desktop environments / window managers? There's likely parts of the previous de/wm running if you didn't kill the parent program (restart X).

$ sudo apt-get install ubuntu-desktop

The trick I usually need if I start with a minimal install. You can change your run level with systemd and use startx to choose your de/wm of choice. Which is simpler for me.

$ sudo systemctl set-default multi-user.target
$ sudo shutdown -r now

$ echo "exec cwm" > .xinitrc
$ startx -- :0

You can go back to the graphical login route as well.

$ sudo systemctl set-default graphical.target
$ sudo shutdown -r now

Just look in /etc/systemd/system/ if you can't remember the name or spelling of the .target.
