[lubuntu] Having a few issues, mouse, touch screen and keyboard.

Came back to linux because I'm tired of Windows. Running into a few issues however. I have a Dell Inspiron 7348, which dell sells with Ubuntu.

First, my mouse icons disspears after I recover from sleep. I read this may have something to do with a gnome daemon, I checked and didn't see it. Any idea's here?
I have the proprietary Intel video drivers installed, at least I think I do.

Also, something I'm not used too, is the jumping. It's so sensitive! I cannot find way to reduce the, or even configure the sensitivity, or some sort of palm detection.

Lastly, at least so far is the keyboard. Non of my built-in keys like volume etc work. Is there a way to enable them? I would prefer to have the FN key set to always on if
possible. But first I would love to just get it working.
