I would need a magnifying glass if the screen was that small ;)

That would prevent me from using the laptop when the workstation is not 
running --- unless maybe I get another display port cable.  Maybe I should do 
that; in that case, I could an USB switch.

Besides, setting up xfreerdp is a somewhat annoying task ...

Well, any device to switch USB devices between multiple computers that doesn't 
make sure that the devices keep their settings would be entirely useless.  
I've never used one, so I don't know what they do --- if I were to buy one, 
I'd have to return it if the devices loose settings when switching.

If I were to make such a switch as you describe myself, it might work for 
keyboards.  IIUC, keyboards have some kind of controller built in which is 
responsible for the repeat rates and delays.  As long as the keyboard is 
powered, it shouldn't forget them.
