[X2Go-User] How to reduce fonts size?

[nicolas.x2go at ecarnot.net]

Hello,

Though I read
https://www.mail-archive.com/x2go-user@lists.x2go.org/msg03049.html
and when using 'Single application' or 'Published applications', and 
running Thunderbird (91.1.2) from a 4.1.0.3-5 x2go server running on an 
Ubuntu 21.10, to my XUbuntu 21.10 desktop, whatever setting I'm trying 
to use about the DPI has absolutely no effect on the fonts size in the 
published Thunderbird.

They are significantly bigger, and don't change either when raising nor 
lowering the DPI setting.

Is this something I could check somewhere in the logs, or does anyone 
has any advice about it?

Thank you.
