Comment 11 for bug 745579

This is not a problem of a primary/secondary monitor. It is a problem of not being able to configure Unity bar position. It's not a bug, it's a design issue/mistake.

Even with one screen setup Unity bar on the left-hand side can be a usability problem (not just a personal preference thing).

I'm sharing mouse and keyboard with Synergy over multiple computers and Ubuntu PC is positioned in far right. There's no way I can fire up Unity bar because it's in the middle of the "synergy" desktop so hovering over it is next to impossible. Ubuntu PC has only one screen and that screen is primary. Therefore "changing primary screen" hack can not be applied here.

I agree what Zordid sad. This fixed left-hand by-design position of Unity bar is crap!
