I’ve this problem when i install metacity and gnome into ubuntu server and access with vncserver.
Press d keyand show my desktop, type s and show the main gnome menu… grrrrr….
into shell ssh install
# apt-get install dconf-editor
after
open Applications\System Tools\dconf Editor
navigate to:
org\gnome\desktop\wm\keybindings
then change the show-desktop keybinding to [].
change panel-main-menu keybinding to [].
SOLVED!!!
