Disclaimer: I know this makes Ubuntu less secure, but nobody else has access to my laptop and I'm bored with typing in my password constantly.

For others frustrated by Ubuntu asking you for a password on your laptop when you restore from suspend or hibernate;

Run gconf-editor
Open Apps -> gnome-power-manager -> Lock

Untick those boxes and it won't nag you again. In my mind, this should be the default when autologin is enabled.

Another issue is the wifi applet, networkmanager, doing the same. This one's easier - open the properties for that wifi network (right-click wifi icon, edit connections. Select Wireless and edit your network) Just tick the bottom box "Available to all users". Kinda makes sense, but I wish it was enabled by default. I imagine the number of laptops that have both multiple users and care to prevent access to a wireless network is fairly small.
