Hello, new to the forum!
I've just got an Acer Aspire One with the Linux Linpus Lite distribution. Very happy with the machine, although the OS gives me a little pain, things don't work like with Ubuntu. Anyway, I have managed to create user accounts I need, but I cannot figure out how to logout to switch user. I only managed to do it via restart, which is not convenient. The 'shutdown' button only has options for sleep, restart, lock screen and shutdown.
