So you can use sudo - like in sudo apt-get?
Try this opens gedit with the same "tool" as is used by among others mintUpdate
If you get the "starting administrative process" and nothing more we know there's an error in gksu
I can't really say why it's become slow to load the panel - I suppose this is at boot?
Also tell us about your hardware - specifically the graphics card

Make a new user and see if it's as slow on that account as well, that way you can rule out that it's not something in your settings.

Hi.

I had a similar problem.
I found out that the reason was that /etc/sudoers had the wrong mode

try this in terminal
sudo /etc/sudoers gedit

if you get a message that sudoers has the wrong mode then do the following

reboot
start mint in recovery mode and type
chmod 440 /etc/sudoers

at least 440 was the correct mode for me

hope this helps
Ketil.
