[winswitch] xpra dpi woes with a server running Ubuntu cosmic

[Perry E. Metzger]

Howdy! I'm testing out xpra with a remote server running
Ubuntu Cosmic and a client running MacOS, and I've been having some
challenges with the setup setting the DPI to weird values.

My impression from reading old trouble tickets is that I need to
install a patched version of the Xdummy stuff but I'm not exactly
sure. What do I need to do, roughly? (I searched and couldn't really
find exact instructions...)

Thanks in advance!
