HiDPI, Gnome/Gtk & debian-10-minimal

[Sven Semmler]

I am re-building all my templates based on debian-10-minimal. HiDPI
scaling works with all programs (Xft.dpi in
/etc/X11/Xresources/x11-common) except for JRE based programs.

In the past, if I installed gnome-settings-daemon and then set the
scaling factor in gnome-tweaks it also worked with JRE based programs.
That was with kicksecure (installed on top of debian-10-minimal by
following https://www.whonix.org/wiki/Kicksecure/Debian) as well as a
full debian-10 and fedora-?? (long ago) template.

Doing the same on a debian-10-minimal doesn't work: the gsd-xsettings
daemon is running, but any configurations I make in gnome-tweaks have no
effect. So my strategy is to see which additional packages kicksecure
installs in the system. Unfortunately there are many. Anyone have an
idea which of these I should try?

Actually I am unsure about debian-10 ... but definitely kicksecure
(debian based) and fedora.

Today I will check my assumption by installing all the packets listed in
my previous post (minus the kicksecure specific ones; will only use
debian repo). If that fixes it, I'll narrow it down from there.

Found this:
https://github.com/QubesOS/qubes-issues/issues/4276

... who knows, maybe I can figure it out and even contribute a bit.

Yup, debian-10 full also doesn't work.

Ignore, this is unrelated.

Didn't work out. None of the packages that are not specific to
kicksecure and are part of the normal debian repo fix the issue. Neither
does debian-10 full.

Not sure where to go from here.

Can't seem to make it work on the plain debian templates. So my choices are:

a) debian-minimal based kicksecure
b) fedora-minimal

The reason I wanted to have "plain" debian-minimal was to get more
minimal (less space / less stuff) as morphing into kicksecure adds quite
some packages.

But now that I have tried fedora-minimal ... I have to say it is a LOT
LESS minimal than debian-minimal just judging by size.

So back to kicksecure it is. I wish I new how to debug this and figure
out what they have done to make it work that is missing in the debian
templates.

Anyone?
