I switched to nemo a long time ago, because I think it's superior to nautilus in many ways. One small thing bothers me however:
Whenever I want to open a document in gedit (or evince, but I'm sure there are other programs as well) not the nemo file-selection window appears but the nautilus one.
I did of course replace nemo with nautilus as suggested in a lot of other posts:
gsettings set org.gnome.desktop.background show-desktop-icons false
xdg-mime default nemo.desktop inode/directory application/x-gnome-saved-search
and also did
ln -s /usr/bin/nemo /usr/local/bin/nautilus
in order to completely replace nautilus, but this doesn't help. Which program/executable is triggered when hitting open (Ctrl+o) in gedit/evince?
