The procedure for setting DPI scaling depends on the presence of the `/usr/libexec/gsd-xsettings` daemon, usually provided by the `gnome-settings-daemon` package:
The procedure for setting DPI scaling is different depending on whether Gnome settings daemon is running or not:
- without `/usr/libexec/gsd-xsettings` running, applications honor the `Xft.dpi` [X resource](https://en.wikipedia.org/wiki/X_resources), which we can then use for scaling.
- with `/usr/libexec/gsd-xsettings` running, applications are prevented from using the `Xft.dpi` resource so gnome specific commands have to used.
- if the daemon is stopped/not installed, applications honor the `Xft.dpi` [X resource](https://en.wikipedia.org/wiki/X_resources) which we can then use for scaling.
- if the daemon is running (`/usr/libexec/gsd-xsettings` process in Fedora), applications are prevented from using the `Xft.dpi` resource and `dconf` values have to set.
Notes:
- the official `fedora-xx` template has `gnome-settings-daemon` installed by default while the `fedora-xx-minimal` template doesn't.
- the official `fedora-xx` template has the `gnome-settings-daemon` rpm installed by default while the `fedora-xx-minimal` template doesn't.
- DPI scaling with `xterm` (or any glib apps) requires the use of a xft font:
- for `xterm`, ctrl - right click in the terminal's windows and select 'TrueType Fonts' (make sure you have such fonts installed).
- or more generally, set the `faceName` Xresource, eg.:

Once you found a value that fits your setup you'll likely want to permanently set the `Xft.dpi` resource. You can do so on a per-template (system-wide) or per-VM basis:
- add (or modify) `Xft.dpi: xxx` in the TemplateVM's Xresource file (`/etc/X11/Xresources` or `/etc/X11/Xresources/x11-common` for whonix-ws-template).
- or, add `Xft.dpi: xxx` to `$HOME/.Xresources` in each AppVM.
