What's the command for executing this "gksudo" (or whatever it is) window from Alt+F2?

I cannot understand what are you asking. Can you clarify, plase? –  enzotib Nov 11 '11 at 18:22

That window doesn't look like quite the same thing I get on my stock GNOME Shell install. Perhaps it has been themed, in which case a link to the theme used in an answer below would be quite helpful. –  Christopher Kyle Horton Dec 14 '11 at 22:47

That cool window in GNOME Shell is only displayed for applications that use PolicyKit. For example, to trigger this window for Synaptic, run this in a terminal:

pkexec synaptic

You can't use pkexec for all applications but only for those that have a pkexec policy file under /usr/share/polkit-1/actions/.

However, it doesn't work when you launch it from Alt+F2 –  Alfredo Hernández Nov 11 '11 at 22:25
    
then why all programs not using PolicyKit, and is it work for unity also??? –  Naruto Nov 26 '11 at 21:59
    
Yes, it works under Unity (but it looks different). –  Alin Andrei Sep 4 at 15:54

For this you can use the command gksu-polkit. It largely behaves the same as gksudo, but taps into the policykit framework. To use it install the package 'gksu-polkit'.

The command is: gksudo synaptic

Actually, as this answer states, this is pkexec rather than gksu or gksudo. –  Eliah Kagan Nov 11 '11 at 20:21
    
It is indeed pkexec, not gksu(do). This answer is plain wrong. –  Victor Feb 24 '13 at 10:21
