[snap] Libreoffice uses the adwaita gtk theme

Libreoffice 6 snap uses adwaita gtk

Libreoffice 6 snap uses a hard path to the icon instead of the freedesktop spec

[Olivier Tilloy (osomon)]

Regarding the icon path, that's expected: if the icon was set to "libreoffice-writer", the deb package for libreoffice wasn't installed, and the current theme didn't have an icon for libreoffice-writer (on my setup only the HighContrast theme has one), then the shell wouldn't be able to display an icon for the app. Snaps can't install icons under /usr/share/icons/, and the shell isn't aware of icons shipped inside snaps.

What theme does the rest of your desktop use?

[Frederik Feichtmeier (feichtmeier)]

GTK Community theme (https://github.com/Ubuntu/gtk-communitheme)- I see - changing to ambiance did the trick. Now the snap uses the ambiance gtk theme.

The theme matching works only for ambiance?

Regarding the icons, most debs - if not all - use the free desktop spec. And it works very well with Humanity icon set (which inherits hicolor in it's index) 99% of the apps work with relative icon paths, even if they are snaps. (this is just a user impression, I got no deeper understanding of how this works)

> The theme matching works only for ambiance?

It works only for the themes that are shipped within the snap.
As of today, for the libreoffice snap those are:

    $ ls /snap/libreoffice/current/usr/share/themes/
    Adwaita Ambiance Default Emacs Radiance Raleigh

That will eventually be fixed, but it will take some time.
For an explanation of why, see https://forum.snapcraft.io/t/use-the-system-gtk-theme/496.

When the theme used by your desktop is not found in the snap, I believe it falls back to the first one in the list, which happens to be Adwaita.

The Humanity icon set doesn't have icons for libreoffice. So if you uninstall the libreoffice debs and install the snap, Icon=libreoffice-writer will get you the only icon available on the system, which will be the hicolor one.
In general, snaps need to ship all the resources they need, they shouldn't rely on the host system providing icons for them.

I have updated the title of the bug to refer to the issue with themes only.

[Mohammad Anwar Shah (mohammadanwarshah)]

Is there any update for this bug? This is unbearably ugly on other Linux distros not having Ambiance etc, especially on KDE

[Marcus Tomlinson (marcustomlinson)]

Is this still an issue? Please run `snap connections` and ensure that the following appears in the output:

content[gtk-3-themes] libreoffice:gtk-3-themes gtk-common-themes:gtk-3-themes -
content[icon-themes] libreoffice:icon-themes gtk-common-themes:icon-themes -
content[sound-themes] libreoffice:sound-themes gtk-common-themes:sound-themes -

If not, you'll need to run `snap install gtk-common-themes` to install the required themes. Then try LibreOffice again to see if there is any improvement.

Hi there! No this is no longer happening on new LO snap installations :)

[Marcus Tomlinson (marcustomlinson)]

Awesome, thanks for confirming :)
