Daniel van Vugt: @vanvugt: 
It is safe to say that, when using Nvidia drivers, the fractional scaling is 
completely broken.

- You can't set the scale differently on different monitors (basic 
functionality)
- The fractional scaling doesn't work at all (even if you set it to be the same 
for both or multiple monitors)

There are several (almost 50) different hardware configurations having
this issue and there are several "workarounds" all of which have their
own issues.

This is an extremely basic functionality and something that is needed as
I have read that *the most common* way to work right now is a laptop
with one external display.  If using Nvidia drivers, that setup does not
work.

Can you tell me how to get involved or what I can do to get this
working? It has been several months and I'd like to solve this problem.
