As in this post

https://askubuntu.com/questions/769417/how-to-change-global-...

I ran gsettings set org.gnome.desktop.interface gtk-theme 'Adwaita-dark' and firefox isn't in dark mode, despite the fact that i have firefox configured to use the system theme and firefox is on GTK according to google.

Help again?

When you set dark mode in the current gnome (with support for dark mode), the following will be set:

    org.gnome.desktop.interface color-scheme 'prefer-dark'

Valid values are “default”, “prefer-dark”, “prefer-light”.

    org.gnome.desktop.interface gtk-theme '(your-theme)-dark'

This is the one you have set.

    $ gsettings get org.gnome.desktop.interface color-scheme
    No such key “color-scheme”

Debian 11. Is it because it's old-ish?

Oh, Gnome 3.38. I'm not sure that version even supported dark mode, only dark themes. I won't comment on aging of Debian ;).

Btw, what version of Firefox are you using? Debian comes with ESR, so chances are, that firefox' "ui.systemUsesDarkTheme = 1" still works (it doesn't in newer releases).

I have 102.6.0esr (came with the OS) and I also installed 126.0. Neither of them has has `ui.systemUsesDarkTheme`.

So anyway do you think that if I upgrade to the latest Debian, your gtk command line will work?

It should; it does on the gnome install: https://youtu.be/Vpkz89gN9zk

Oh man that's such a nice feature.

I guess now I have a reason to upgrade.

Thank you!
