LXDE Forums

I have 4 laptops and 2 desktops, all with LXDE desktops, 3 Mint 11, 1 Mint 10, 1 pclinuxos and 1 Lubuntu 11.10. The pclinux does not really count because it is a left-over on a retired desktop. The competition is between Mint and Lubuntu. I favor Mint because it is more reliable, Wine seems to work ...

Preferences/Power Management is the Gnome Power Manager if installed.
