Files
- /var/lib/flatpak - global flatpak state (system-wide installed apps and repos)
- ~/.local/share/flatpak - per-user flatpak state (locally installed apps and repos)
- ~/.var/app/ - per application state (configuration files and cache)
Basic usage
To install an application, e.g. Thunderbird, run:
user $flatpak --user install org.mozilla.ThunderbirdTo run the application use created .desktop file or run:
user $flatpak run org.mozilla.ThunderbirdTo update installed applications and runtimes:
user $flatpak updateTheming
Flatpak documentiation offers a good guide about desktop integration and theming.
GTK
Flatpak applications don't follow the system's GTK theme by default. First find out what's the current GTK theme, e.g. Materia-dark-compact, and then install it for Flatpak applications to use. [2]
user $gsettings get org.gnome.desktop.interface gtk-themeuser $flatpak install flathub org.gtk.Gtk3theme.Materia-dark-compactFixing jagged fonts on Wayland
Some users report jagged fonts on Wayland. The workaround is to install gnome-settings-daemon.[3]
