If you find your GNOME menus rather slow when accessing them, you can greatly speed up things with
echo “gtk-menu-popup-delay = 0” >> ~/.gtkrc-2.0
Alternatively, just edit the .gtkrc-2.0 file in your home directory and add the line gtk-menu-popup-delay = 0
My ubuntu does not have a .gtkrc-2.0 file.
Is there a way to find what it is currently set at?
You can create one with .gtkrc-2.0 . The first of the two commands above creates it automatically.
