I have installed Ubuntu Gnome 14.04
The problem is :
Nautilus(I think it called "Files" in gnome-shell) has no Minimize/Maximize button !
I have enabled gnome-tweak-tool -> Windows -> Maximized/Minimized
, but Nautilus has not Minimize/Maximize buttons!
Any ideas?
Gnome-shell
usingdconf
as instructed in answer2
works right away. Oh yeah, pardon, but you meant Nautilus also :-) let me check next
