Also this only effects my HP dv7-4285dx laptop after fresh install, and my desktop seems to work fine. I Googled and saw that several KDE users some months ago had a similar issue. So maybe it's related to X, systemd, or something else at the low level? A lot of the users reporting the issue reported that they experienced it only on certain machines, and in every case it was a HP laptop in the dv-whatnot series. This may help trace the problem down.

Version of unity- settings-daemon is 14.04.0+14.04.20140414-0ubuntu1. Possible that this bug either affects unity-settings-daemon, gnome-screenshot, or something else. I expected Print to take a screenshot. Ditto for CTRL+Print and ALT+Print. All my settings under Keyboard Shortcuts are normal. Everything worked for every prior release of Ubuntu with the Print key taking a screenshot. Also, neither CTRL+Print nor SHIFT+Print work at all. If you reassign the keys for taking a screenshot, to any other keys, gnome-screenshot works as expected. Assigning either of those three key/key combinations to any command does not work. ALT+Print strangely enough works without issue. Running gnome-screenshot from the terminal also works without issue. Unlike the other bugs I've seen that sound similar, I do not hear a sound at all when pressing any of those three key combinations. Toggling the magic sysrq key does nothing for this issue either.
