Description Uwe L. Korn 2009-04-03 10:57:02 UTC 
As there is a checkbox for mirroring the whole screen, so that it is fully visible on both monitors, there should be a option that the highest available resolution of both screens is used and one of the monitors just shows a part of the screen.

How it has to be done manually at the moment (in this order):
  1. Start your Gnome session
  2. Connect your second monitor
  3. Run "xrandr -s 0"

If you connect your second monitor before you log in, the resolution will be turned on the highest both screen share, which sometime is 640x480 even if both monitor provide higher resolutions but they just have a different aspect ratio(?) (e.g. 4:3 or 16:10). If there is a small resolution choosen at the log in, it is highly possible that elements that are locked on the gnome-panel get mixed up in their order.

This was initially reported in Launchpad: https://bugs.launchpad.net/bugs/351427

The primary use case for mirror mode is presentations. You want to be able to see the exact same thing your audience is seeing. Therefore the common denominator, the lower resolution of the two is a good default. 

Question is, whether the case you are describing is relevant enough to clutter the UI. Can you elaborate on that "portion of a screen mirror" use case?

No response since 2009. Closing.
