On Ubuntu 11.10, I'm seeing modals from many applications show up on a different monitor from their parent application. In this example, Firefox, the application on the right most monitor, has popped up a modal dialog in the center monitor.

You'll notice that it is not just on the wrong monitor, it's also positioned horizntally against the left edge of that monitor. Vertically, it's centered.

This happens for at least Firefox, Eclipse and gedit modals. It seems like it's all applications. It doesn't matter which monitor the parent application is on, the modals are always on the left edge of the center monitor.

There is a workaround on the linked bug history (using compizconfig-settings-manager) that seemed to work pretty well for me. It was posted by Jordon Bedwell on 2012-07-16. – Jason R Nov 8 '12 at 16:51
But the workaround seems to be gone in 12.10. OTOH, there should be a permanent fix in the up and coming 13.04 – Prof. Falken Mar 14 '13 at 12:29

The primary and the secondary display are one whole display. The modal dialog is constructed to be shown center on the screen. I suppose that this center is the "border" between the both monitors..this is the only one reason i have :) But i want all screens and dialogs to be shown on the primary screen only, too.
