I've used the command 

unity

to restart Unity without logging out, but recently that's been also logging me out. I've also tried using 

unity --replace

but that does the same thing. Can someone either help me get that command working correctly again or tell me another way to restart Unity while still keeping my current session?

If I try

sudo service lightdm restart

my screen goes black, and I just end up restarting my machine entirely.

  • I have the same problem. Restarting the X server with this also logs me out. Maybe you could file a bug report. – Joschua May 19 '15 at 10:09
  • That indeed looks like some bug. I've got the same problem. – kcpr Jun 30 '15 at 09:12
  • @kcpr Have you found a solution? I'm now on Ubuntu 16.04 and I still don't know how to restart Unity without logging out. :/ – Joschua Jun 29 '16 at 10:37
  • @Joschua to be honest I still use Ubuntu 14.04. compiz --replace works for me though. – kcpr Jul 15 '16 at 21:47

I believe this is intended behavior. The Display manager (in this case, lightdm) creates and manages the login/x session. When you restart the display manager, you kill the x session and the currently logged in session and must log back in and establish a new session.

Someone more knowledgeable correct me if I'm wrong, but I believe this is the case.

I use Ubuntu 14.04 and compiz --replace seems to work for me.
