I think you have four options:
- Use the Faenza-Darkest icon theme. (Is there a reason to not do this?)
- Replace the icon (which you don't want to do).
- Edit the app's configuration to change the icon.
- Make your own lightweight icon theme to set your desired icon.
Edit the app's configuration to change the icon
Edit /usr/share/applications/diodon.desktop
and change Icon=gtk-paste
to Icon=/usr/share/icons/Faenza-Darkest/actions/22/gtk-paste.png
Note that editing system files is generally a bad idea. You might be able to copy diodon.desktop
to ~/.local/share/applications/diodon.desktop
and then edit it. I'm not sure if that would work.
Make your own lightweight icon theme to set your desired icon
This is probably the best solution, but it's a little trickier. (See also this more thorough description for creating lightweight icon themes.)
Run this from a Terminal:
# Create a new theme containing the icon we want
mkdir -p ~/.icons/Faenza-Alan/actions/22
ln -s /usr/share/icons/Faenza-Darkest/actions/22/gtk-paste.png ~/.icons/Faenza-Alan/actions/22/.
# Copy the theme config and modify it for our new theme
cp /usr/share/icons/Faenza-Darkest/index.theme ~/.icons/Faenza-Alan/.
sed -i -e "s/Inherits=/Inherits=Faenza-Dark,/g" ~/.icons/Faenza-Alan/index.theme
sed -i -e "s/Faenza-Darkest/Faenza-Alan/g" ~/.icons/Faenza-Alan/index.theme
Now open Appearance and change your icon theme to Faenza-Alan.
Now your new theme will persist regardless of system upgrades. (Unless Faenza removes the gtk-paste.png icon. If you're worried about that, use cp
instead of ln -s
. But you won't get updates to the icon.)
My Faenza-Alan looks like this:
In testing this, I see that it's probably a bug that Faenza uses a light app-indicator icon for any of the dark themes. Anyone know where you can file a bug?
