I'm using unity 3.8.16-0ubuntu1~natty1 and I don't see --replace in the man page. It does accept the option but I don't see any difference; both with and without, the existing instance crashes with 'Segmentation fault'.
With or without other options, I would expect: * unity /with/ --replace to quit rather than crash the existing instance, and * unity /without/ --replace to say it's already running and quit. Take Compiz for example: james@james-ThinkPad-X60-Tablet:~$ compiz compiz (core) - Error: Screen 0 on display ":0.0" already has a window manager; try using the --replace option to replace the current window manager. I've attached output from the terminal for when a second instance of unity is run. I added space-hash-comment to note when I did something. See lines starting with space-hash (' #'). ** Attachment added: "692569-unity-1st-instance" https://bugs.launchpad.net/ubuntu/+source/unity/+bug/692569/+attachment/2284979/+files/692569-unity-1st-instance -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/692569 Title: unity --replace would be nice To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/692569/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
