Some more thoughts on network manager.
Compared to wicd, it's more cumbersome with the VL install. What I've had to do is select the wireless connection and then edit the connection to provide the password. It's not asking when I do the initial selection. I was dinking around with Mint 14 XFCE and I didn't have to go through that process. When I selected the wireless router, it immediately asked for a password.
Is there a specific reason why we're looking to get away from wicd and use network manager?
