I am using OpenSUSE Aeon and would like to simply use the default blue Gnome accent colors. I know, a vain pursuit that is perhaps not encouraged, but maybe someone can help me anyway. For Gnome itself, that is obviously easy, but for the login manger GDM, it does not seem to be possible.
I tried the following command, but it says that it cannot find the machinectl
command: machinectl shell gdm@ $(which gsettings) set org.gnome.desktop.interface accent-color "blue"
So my question is: Is this principally not possible because of Aeon being immutable (which is obviously fine), or am I simply missing something?
