Hello. I’m using Debian testing with KDE Plasma 5.27. I’m experiencing a problem where GTK Flatpaks are not following the chosen GTK theme despite giving them permissions to access .themes and .icons folders found in the home directory. I tried the running the following commands in the terminal:
flatpak override --filesystem=xdg-config/gtk-4.0:ro flatpak override --filesystem=xdg-config/gtk-3.0:ro
I even tried to specify a certain GTK theme to be chosen, that resulted in the flatpak changing to an ugly white-adwaita theme. I should note that this is happening exclusively with GTK Flatpaks, QT Flatpaks and GTK deb packages don’t seem to have this problem. What am I missing here? Any help would be appreciated.
In this video explains everything you should know about flatpak theming.
As others said, you probably haven’t installed the chosen theme yet.Here is an alternative Piped link(s): https://piped.video/watch?v=IYXlgzrZRIE

I’m open-source, check me out at GitHub.
Have you installed xdg-desktop-portal-gtk?
xdg-desktop-portal-gtk?
Yes, it’s already installed.

Is it being forced to look for a theme installed via flatpak maybe?
How do I know that exactly?
Apparently there has been a problem with gtk4 apps and theming in flatpak, only supporting adwaita light and dark - only found vague reference to it though, nothing concrete.
Try
flatpak-metadata socketsTo see if you can find the GTK_THEME environment variable.
You’ve given it permission to access the themes folder, now you need go point it at the themes
sudo flatpak override --env=GTK_THEME=my-theme sudo flatpak override --env=ICON_THEME=my-icon-themeWhere my-theme is the theme name, e.g. Adwaita-dark
Apparently the flatseal gui has some functionality to set the theme too! Will check it out tomorrow to see what’s up.
here’s the same as text
sudo apt install xdg-desktop-portal-gtksystemctl --user edit xdg-desktop-portal.service- paste these two lines
[Service] Environment="XDG_CURRENT_DESKTOP=sway"systemctl --user restart xdg-desktop-portal.serviceThis also refused to work unfortunately.
