I have switched to gnome because of lotus, and see one problem with power button.
I can't configure it to be really in "Ask" mode. I have set in gnome-power-manager:
When power button is pressed : "Ask me"
but this does not help. laptop just shuts down.
This mode works well when I switch to XFCE (anyway using gnome-power-manager).
Running fc6 on an IBM/Lenovo t60p.
