Oh, you're correct, gksudo works. In that case, my original title is quite misleading. It should probably be changed.
Anyway, it seems like gksu has become the default password input. First thing, it is used in the System → Administration menu when launching Synaptic. That can easily be changed to gksudo by using Alacarte, but that's not the only place it is in use. When launching the update-manager without administrator privileges (which it does unless run from a terminal), and pressing the Install Updates button, gksu pops up asking for the password. -- gksu doesn't recognize the password https://launchpad.net/bugs/59079 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
