Attachments: The checkbox I'm referring to

The checkbox I'm referring to

SUMMARY
The widget used for the "primary" setting is a checkbox, which suggests that the feature can be enabled/disabled.
In actual fact, the user is not allowed to uncheck the checkbox. Instead they must click on another screen and check the checkbox from there.
I think it should be clearer that this checkbox is one-way.

Maybe it should be greyed out when it is enabled?
Or maybe it should be replaced with a button. The label in the left column could be "Is primary:" and the text on the right could say "Yes" or "No". If it says "No", then there will also be a button next to it saying "Set screen as primary".

STEPS TO REPRODUCE
1. Have at least two monitors connected
2. Open Display Configuration
3. Click on the primary screen
4. Try to disable the "Primary" checkbox

OBSERVED RESULT
It doesn't work

EXPECTED RESULT
I would expect the checkbox to be unchecked.

This needs a better UI; what we want is a single global combobox that lets you choose which of your displays is primary.

Of course this will change back once we move to a system of marking displays as primary, secondary, tertiary, etc.
