I switched recently from KDE 4 to MATE (Arch Linux) and can see the
same behaviour with MATE: x2goserver/nxagent ignores the dpi settings
set in x2goclient.

I had not had time to investigate this further and for now worked
around that by placing two launchers on my desktop and running them
manually in the current session:

For local sessions:
gsettings set org.mate.font-rendering dpi 107

For x2go sessions:
gsettings set org.mate.font-rendering dpi 96

It works on the fly, only some apps (skype) need to be closed and
restarted.

I believe one could use .config/autostart/ and some script with tests
of the environment to set the proper DPI during log-in phase. This
would resolve the issue with uncleanly terminated sessions. Perhaps it
may not work for published apps.

I hope to look at the issue later (well, just a cheap promise...)
