GNOME 3 has been extensively tested on single monitor systems and somewhat on dual monitor systems. Further testing of multiple monitors is required to identify issues.

You will need to be able to run openSUSE 12.1 on a machine with at least 2 (ideally more) monitors. You will be testing GNOME shell with multiple monitors, looking for both bugs and usability issues. You learn how to investigate complex issues that blend both technical and UX elements. Any issues found will need to be documented and possible workarounds/solutions proposed.
