Hi,
GNOME System Monitor uses pkexec for doing tasks the user otherwise would be not allowed to do (kill process of other users, renice, etc). But pkexec is only the first option, support for gksu and gnomesu are theoretically also supported as fallbacks, but as far as I see these are not supported by major distros anymore (not supported meaning not provided, not installable).

I am eager to hear some suggestions on replacing pkexec-based solution, or maybe System Monitor should not be part of the default Fedora.


gksu and its ilk aren't substantially better than pkexec. A proper solution would be talking to a system service over dbus (or some other protocol).
