authentication

Whenever I try to run a program from gnome gui, I get message

Authenticated is required to run the Gparted Partition Editor

The same goes for all programs that need root permission and I try to run from 'System tools' in my gnome-fallback.

However the same user can become root in gnome terminal with no problem (I added the user to sudoers). I must mention that I've changed the user's password after OS install, so I think I need to update something but don't know what. I appreciate your hints.

Will final version of 12.04 use the power management changes found in kernel 3.3

In this case, kernel 3.3 has seen some very good power management enhancements that are… >>> More
