I found one solution (assuming you're using Gnome) #Empty the list of recently used documents echo "" > ~/.recently-used
#Make the file read-only,#Such that Gnome can't actually add new 'recently used documents' to the file.
sudo chmod 400 ~/.recently-usedNote, i have no idea whether or not the file ".recently-used" exists in Trisquel version of Gnome.
But you can check whether or not it does by, ls -a ~/ | grep recently-used source: http://ubuntuforums.org/showthread.php?t=91154
