I'm using Arch Linux and currently installed Xfce4, which after I log in (using LigthDM) opens an instance of the Nemo file browser. This happens regardless what I set as the default file browser (I also tried Nautilus and Thunar). This happens only with Xfce4, using Cinnamon or Gnome doesn't reproduce this behaviour.
I checked the Application Autostart settings from the Session and Startup menu, but there is no entry for Nemo or any other file browser. I also checked the contents of
~/.config/autostart/, but there aren't any file browser related entries.
Any idea where this behaviour could be originated, or any suggestions what I could try next?
