    Hey guys. just this weeeird issue with brightness control over Fn keys described in the header, all other Fn keys work properly, except for when i push Fn+F4 or +F5 i see the AW brightness indicator icons when i hit the combo, but they refuse to go up or down (to actually change the brightness) - anything I could be helped with?
    Also I started noticing that to get switchable graphics working I have to restart my system, is that also typical, because it also started recently?

    Did you install non-Dell Ati drivers? Than it's a common issue.
