suspend/hibernate and resume on USB

view story

http://ubuntuforums.org – Well, resume on USB works really well with all forms of suspend/hibernate and also (my favorite) suspend-hybrid. However, I have 2 issues. I've searched around, but I can't seem to find anything posted that works for me. 1) I don't seem to be able to wake my frontend using my MCE usb ir remote. It worked the first time I tried (but maybe I just bumped the mouse?). But now I can only wake by usb keyboard or mouse. 2) I don't seem to be able to make mythfrontend suspend/hibernate the computer. I enabed the shutdown menu and gave it different commands, but they all seem to require su (Hardware)
