It currently doesn't build on Rust 1.65.0

Hey!

Thank you for bringing this to my attention. LibC uses some different types for some different platforms. All the platforms on docs.rs show that c_char is an i8, so I used that. Turns out for most ARM devices it is not, I guess I need to watch closer next time. Can you confirm that you are indeed using an ARM device? If you have the time and interest, could you try to compile the referenced branch? That would massively help me.

Thank you again.

PaddiM8 commented 1 year ago

I am indeed on ARM (Asahi Linux). The referenced branch does compile! Very nice, thank you for getting on this so quickly. I'll try it and make sure it actually works as well.

PaddiM8 commented 1 year ago

Hmm I can't seem to log in. It thinks the password is incorrect. Entering the (correct) password a few times results in being locked out for some minutes, so lemurs might give it the wrong password?

coastalwhite commented 1 year ago

Is there any chance you can switch to another TTY and give me the contents of /var/log/lemurs? There might be problems with PAM or the rust bindings to it, we are using.

PaddiM8 commented 1 year ago

Yeah sure, I have plenty of time right now so don't worry! After pressing enter, I could see some text flash for a split seconds to the left of the input fields. I think it said it failed to login or something like that, but Icouldn't really read it.

It is logging in as it supposed to. The Wayland session is crashing, though. What Wayland desktop environment / window manager are you using? These problems are kind of difficult to debug at the moment. You could try to update to the develop branch, as I have been working on improving the logging there a bit.

PaddiM8 commented 1 year ago

I switched to the develop branch and merged the new changes. Now I did get some good output from Sway:

My user is in the seat group. Tried with plasma and Hyprland as well with no success. Hyprland gave similar errors while plasma didn't give me any information (not sure how plasma works though, it just came with Asahi).

I know ly has issues with arm64 as well, I wonder if it's related to something similar.

coastalwhite commented 1 year ago

It might very well be. A lot of the code from this repository is inspired from ly. Wayland is usually very difficult to debug. Did you try with polkit instead of seatd? This should work well with SystemD.
