From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

You must not have xdg-desktop-portal-gtk.
I think one recent release was also bugged but it’s fixed if up to date.
I do have
xdg-desktop-portal-gtk
on Debian Stable, which is currently at 1.14.1-1. I'll look around to see if there's more documentation on this method, because I would prefer to not use the debug variables if possible.Edit: I launched with GTK_DEBUG=interactive and I can see the theme inside the Flatpak gets set to
Adwaita-empty
instead of my actual theme, which does get properly returned viagsettings get org.gnome.desktop.interface gtk-theme
The way to test what GTK actually gets is this command:
gdbus call -e -d org.freedesktop.portal.Desktop -o /org/freedesktop/portal/desktop -m org.freedesktop.portal.Settings.Read org.gnome.desktop.interface gtk-theme
That gets my normal GTK theme properly. I found a little more discussion on this here. Nothing very actionable but I did also confirm that my
xdg-desktop-portal-gtk
is running. It seems like this is supposed to be working, but I have a mostly stock Debian 12.1 KDE install and something seems to be wrong somewhere in the chain. I've also tried multiple GTK Flatpaks with the same results.Edit: Also, I have both my themes folder exposed and the theme installed as a Flatpak via the linked script.
