I just set up Niri + Noctalia, previously I was running KDE Plasma. The distro I am using is EndeavourOS (which is awesome!)

I am able to successfully install Noctalia, and by reading the docs, I was able to figure out how to set up unified theming for both GTK and Qt-based applications.

As I am using the Noctalia greeter for the unified sort of aesthetic, I’m not using sddm anymore, and I had Howdy set up for face recognition (yes, I know it’s not as secure, but I like the convenience and my laptop has the IR sensors to do it). What PAM file do I need to change to get that working on the Noctalia Greeter? The “greetd” file doesn’t seem to be the one, do I need to create a new file, and in that case, what should it be called?

It would also be great if I could get the Noctalia Polkit thing (system auth prompt thing) to work with Howdy too, but I was never able to make it work even on KDE Plasma, so not sure if that’s feasible

Second question, I don’t know why, but Thunderbird does not want to open via the launcher after Noctalia was installed. Weirdly enough, it does launch when run in the terminal (“thunderbird”, no special flags or anything), or when you right click in the launcher to do secondary functions (compose a message / check address book). Right now I’m just opening Thunderbird via the address book, which is a little inconvenient, so is there any way I can fix this?

Third, I can’t seem to get KWallet to unlock automatically on login. I have it set up as “kdewallet”, blowfish encryption with login password set up, tried deleting it and making a new one, but it still doesn’t work! I think this is in a similar vein to the Howdy thing where I need to add a line or two to the PAM file to make KWallet autostart. Alternatively, I could go with Gnome Keyring (which has a bit more documentation on the Noctalia docs it seems?)

Finally, does anybody have some tips on Niri/Noctalia, any extensions or plugins that I should look at, etc.?
