GDM Login photo support

[bashfulrobot]

Hi there, I am wondering if:

a) does Stylix support setting the user photo at the login screen, or; b) are there plans to?

Thank you.

Just for reference, here is my hacky way of doing it currently:

system.activationScripts.script.text = ''
      mkdir -p /var/lib/AccountsService/{icons,users}
      cp ${user-settings.user.home}/dev/nix/nixos/modules/desktops/gnome/.face /var/lib/AccountsService/icons/${user-settings.user.username}
      echo -e "[User]\nIcon=/var/lib/AccountsService/icons/${user-settings.user.username}\n" > /var/lib/AccountsService/users/${user-settings.user.username}
'';

What could be neat is if you have a single profile photo setting, and then it configured the above, and placed the .face photo for the login screen.

With that being said, I had discovered the .face method for the lockscreen, but have not tested if the activateScripts method alone would account for the lockscreen as well.

does Stylix support setting the user photo at the login screen

AFAIK, unless your user photo is your stylix.image, this is currently unsupported.

For reference, Stylix applies stylix.image to services.xserver.displayManager.lightdm.background:

are there plans to?

This sounds like a neat feature. However, I think this exceeds the scope of Stylix and should instead be implemented upstream in the appropriate NixOS and Home Manager modules.

Yes, I agree this may be more appropriate to implement upstream.

I believe GDM supports setting the user photo through a D-Bus API or something similar, but it's been a while since I used it so I can't remember the details.
