I have been facing this issue after I have installed multiboot utility for usb keys. Multi-system.
It has asked me something like " do you want to enable gnome icons" ? And I have been thinking that it is for the bootable usb stick. So I didm yes! But no, it has twisted my ubuntu desktop settings.
Because the normal way from CLI,did not work
, sudo gconf-editor
, tick, and un-tick some fields in /desktop/gnome/interface/menus_have_icons
I have installed UBUNTU-TWEAK
sudo add-apt-repository ppa:tualatrix/ppa
sudo apt-get update
sudo apt-get install ubuntu-tweak
and I have "un-selected" one field with icons in menu. Please see attached picture. And it has worked so far fine, the stupid icons from ubuntu right-click are gone!!!
