Ok, finally we have the use case. I was thinking of a completely
different setup.

IMHO for talks our solution is pretty ok. In fact, talks were the
driving force behind our decisions. Projectors typically have 1024x768,
and there's almost no laptop with less than 1024x768 on its internal
display.

hand-select the 1024x768 resolution for the talk.

I do that all the time.

panning solution, but it is not good for giving a talk, if you have to
scroll to see the complete content for your screen. So it perfectly does
make sense, but you have to render the contents two times, once for each
resolution, so you can't use the same framebuffer. How you should deal

What you're asking for is application support. To the best of my
knowledge *no* application on linux has support for something like that
right now.
On MacOS this is different, of course.

with different aspect ratios of displays is however unclear. Scaling
horizontally seems to be the only way to go then.

I don't give a damn, if the aspect is wrong on my laptop's display
during a talk. I'm also not interested about the quality of the display
of the laptop, as you're standing in front of your laptop, and cannot
visualize single pixels at all due to the distance.

The problem is not sax, but code implementations. At least X.org drivers
simply don't allow it yet. I don't know if some of the proprietary
drivers can do it.

?
Xinerama and multidisplay setups work with all (maybe except intel under
some circumstances) drivers with different resolutions.
