Fedora 29 HiDPI Resolution

[Daniil Travnikov]

Could anyone tell me how to put the Xft.dpi on Fedora 29 only once? Because when I am creating AppVM it is always with another HiDPI option, less then his own Template. I mean changes working only on Template, but not in AppVM's.

How are you trying to do it?

For example in Debian 9, Whonix WS and Whonix GW I am doing this:
"
echo Xft.dpi: 240 | xrdb -merge

set in /etc/X11/Xresources/x11-common (for Whonix in: /etc/X11/Xresources/x11-common)
Xft.dpi: 240
"

and it is affect not only Template, it works for all new AppVM's too.

But when I am trying to do the same for Fedora 29, it is works only for template, not for AppVM's.
Instructions from here: https://github.com/Qubes-Community/Contents/blob/master/docs/customization/dpi-scaling.md

Also for Fedora 29 I tried this:

1. sudo nano /etc/dconf/db/local.d/dpi

[org/gnome/desktop/interface]
scaling-factor=uint32 2
text-scaling-factor=0.75

2. gsettings set org.gnome.settings-daemon.plugins.xsettings overrides "[{'Gdk/WindowScalingFactor', <2>}]"

3. gsettings set org.gnome.desktop.interface scaling-factor 2
gsettings set org.gnome.desktop.interface text-scaling-factor 0.75

Maybe someone solved this problem or I missing something?

Also on Fedora 29 Template I tried this command:

[user@fedora-29-clone-1 ~]$ echo Xft.dpi: 220 | xrdb -merge

and got this:

<stdin>:0: warning: Unknown encoding: C.UTF-8

All other command looks good for main Template, but without any effect for AppVM's based on Fedora.

Also I tried gnome-tweaks (https://apps.fedoraproject.org/packages/gnome-tweaks):
$ sudo dnf install gnome-tweaks

Chose 'Fonts' tab and changed 'Scaling Factor' on 2.70

Changes goes immediately. But still when I am creating new AppVm, it is without this changes. Even when in this AppVM I am starting the 'gnome-tweaks' looks as if nothing changed. But if I start Fedora 29 Template- here is all ok.

I ran into this too, and as far as I can tell, it is a Fedora bug.
The extant locales can be found with locale -a
C.UTF-8 is not among them. So the default locale is installed! But
C.utf8 is. You can set permanently by running the following in your
template:

localectl set-locale LANG=C.utf8

Once you do this, xrdb will accept your command and you should be able
to get your hdpi in the template. (I think you are already aware
of the subtleties when gnome-settings-daemon is running.)

Most of the rest of the world seems to use "UTF-8" not utf8.
So I worried there might be some compatibility problems. But
nothing bad so far.

Still the same problem:

[user@fedora-29-clone-1 ~]$ localectl set-locale LANG=C.utf8

[user@fedora-29-clone-1 ~]$ echo Xft.dpi: 220 | xrdb -merge

<stdin>:0: warning: Unknown encoding: C.UTF-8

Also I tried to install 'glibc-all-langpacks' package, but nothing.

Today I have had another problem which I think indicates that the problem is not only in Fedora 29, it could me in Qubes too.

So, I today I had a problem with encoding when I tried to open one of my .txt file in 'gedit' editor.

To solve this problem I installed 'dconf-editor' package and started to configure it in Fedora 29 Template:

I gone through 'org - gnome - gedit - preferences - encodings' in 'dconf-editor' and set - ['UTF-8', 'WINDOWS-1251', 'CURRENT', 'ISO-8859-15', 'UTF-16']

Problem was been solved but guess what happened next? :)

This changes applies only in Template, because when I started AppVM based on Fedora 29 I repeat this sets in 'dconf-editor'.

I hope this is not too much off topic but I'm stuck on getting dom0/XFCE in Qubes R4.0.1 to support HiDPI.

I tried all the documented stuff I could find but they only affect the font while HiDPI should affect every pixel of the screen and not just fonts/text.

You can find a detailed explanation of what I tried exactly and more here https://github.com/QubesOS/qubes-issues/issues/1951#issuecomment-518917371
