gdm was failing to start for me, because smarcard.desktop was missing

I use yubikey for gpg & ssh, and not for "smartcard authentication".
I tried hard to not have any smartcard login on my gdm screen.
I removed /etc/xdg/autostart/org.gnome.SettingsDaemon.Smartcard.desktop which i think is an allowed action.

I installed updates, gdm didn't start anymore because Smartcard.desktop is required to start settion and was unable to start it without it.

Doing sudo apt install --reinstall -o Dpkg::Options::=--force-confmiss gnome-settings-daemon ressurected ability to start gdm

But also ressurected Smartcard.desktop.

How do I disable gdm to not attempt smartcard logins, when my system a) is not enrolled to use or trust any smarcards via pam or anything b) it is a yubikey with gpg certs c) i want gdm to still show and allow login with locally configured user despite smartcard plugged in

I'm sorry, but that's not a legit action: removing a required component is not the way to handle this case.

smart card login can be disabled "properly" by using gsettings

 sudo -u gdm env DCONF_PROFILE=gdm settings set \
  org.gnome.login-screen enable-smartcard-authentication false

Or use https://github.com/realmazharhussain/gdm-settings
