Comment 4 for bug 287328

when i change the brightness, the right click mouse option disappears. I'm
using the laptop mouse, and if i right click nothing happens. As for the
difference between our bugs with my function keys getting stuck "on", i'm
not sure. I also cannot type anything in when this happens. I haven't
tried a ctrl+alt+backspace when this happens, but i will as soon as i finish
what i'm working on. I also cannot get my suspend or hibernate function
buttons to work. Can you get any function button combos working properly?
Also, i heard that this may be caused by the gnome power manager, so what
i'll try next is killing that and trying the function combos again. Either
way, i'll let you know what my results are.
