When I change the screen resolution of my laptop from 1366x768 to 1024x768 via [Displays ...], the entire screen is still filled, stretching the picture uglyly. How can I have a pixel wise 1-to-1 mapping such that the original proportions are preserved?
This I need particularly when I want to mirror the screen together with a beamer.
(In 9.10 it somewhat depended on the displays available at startup. If a lower resolution screen was added later on, proportions were retained)

This is a lenovo X121e and:

(What I found odd when running above is that it took so long)
