Public bug reported: 1) Go to System > Preferences > Sessions > Startup Programs 2) Click "Add" 3) Type something in input field "Startup Command" 4) Press Enter -> nothing happens. You have to either tab to Ok, or look for underlined O in Ok, or take mouse and click button with mouse.
I think that 'Ok' button should be default and activate on Enter when typing in "Startup Command". ** Affects: control-center (Ubuntu) Importance: Undecided Status: Unconfirmed -- In gnome-session-properties no default button when adding startup program https://launchpad.net/bugs/80826 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
