I'm not working on Compiz/Unity anymore, but I agree with the bug description and the comments to where compiz/unity headed to today.
We had a lot of stability problem at the time, hence this helper to reset unity (which is never used in the session itself to start unity). Stephen's team will handle it. I'm accepting the SRU nomination for trusty as well. ** Also affects: unity (Ubuntu Trusty) Importance: Undecided Status: New -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

I'm trying to get a setup with two different Unity desktop sessions running at the same time. One for the local desktop, one for a remote desktop. This almost works, except that when starting the second Unity session, the compiz process that belongs to the first one is killed because of this code in /usr/bin/unity: # kill a previous compiz if was there (this is a hack as compiz can # sometimes get stuck and not exit on --replace) subprocess.call (["pkill", "-9", "compiz"]) Commenting this line makes both desktop sessions work fine. This kill is far too harsh. If you want to kill compiz, you should make sure that you are killing it in the same DISPLAY as the session that you are about to start, and not just every possible compiz process that is running. Please consider either removing the kill or making it apply only to processes in the same DISPLAY. Thanks.
