I can't seem to create launchers on Ubuntu (using crouton on a Chromebook) running 12.04. I've searched everywhere and can't find anything about it. I have the Acer c7 Chromebook if that matters.

P.S: If anyone could also help me with my sound issues, I would appreciate it. If i play any media in Chrome OS and then start Ubuntu, I can't hear any sound in Ubuntu and vice versa. It depends on which OS I play sound on first. If I restart, then I can switch which OS can play sound.

Any help is greatly appreciated.
