Bug description:
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.
[Impact]
Running unity script will kill the unity processes in different displays
[Test case]
- Run unity in DISPLAY=:0 and in DISPLAY=:1
- Launch the unity script in DISPLAY=:1, it should kill and restart only the unity
instance running in DISPLAY=:1
