Software update or Add/Remove Software does not work in LXDE
I've installed F15 Gnome 3 and after a while in using this interface, I decided I rather go back to the LXDE desktop. so I've removed GNOME and installed LXDE.
I'm not sure if it worked in GNOME 3 - but now in the LXDE I'm unable to install software using Add/Remove Software applet or check for software updates.
When I attempt to do so - I get an error message telling me that "Authorization failed" - it doesn't even prompt me for the root password and I've resorted to having to do the install of new software and updates through the command line using su and then issue the commands "yum install ..... " and "yum upgrade".
Does anyone know how to resolve this issue?
