Take the 2-minute tour ×  I know about unity --reset command.
But how can I simply restart Unity without resetting its

Answers  up vote 55 down vote accepted  I don't use Unity but
given what I know of its mechanics, this should work:   You'll
want to stick that in a run box (Alt+F2) rather than a terminal
or it'll break when you exit the terminal.  If you want to run
it from a terminal use:  setsid unity share|improve this answer
That's correct. Although, logging out and back in works better
in my experience (I'm using Unity as my main desktop environment
at this point) –  jrg Mar 24 '11 at 14:15 A good way to do it in
a terminal, in case you want to see debug messages, is setsid
unity. You can close the terminal when ever you like, but you'll
still get the terminal output made
