Re: The "permanent" workaround...
1. It is only expected to work on Ubuntu 11.04 natty. Andrea's comments suggest the same workaround won't work on Ubuntu 11.10 oneiric.
2. You need to make sure the change to monitors.xml is still there. Sometimes it gets overwritten when you log out and in again.
If no one else has this bug in progress after 11.10 is released, I will do it myself. With a configuration option, or something, to allow you to put the launcher on the primary screen, or default to the left-hand screen.
