I noticed it's relatively easy to switch the nightly groups() call to pre_exec(nix::unistd::setgroups(...)), which is effectively what is done under the hood.

This allows us to use the stable toolchain while awaiting stabilization.

Also adjusted some tests that wouldn't compile on stable.

Hi, I recently discovered this project and would love to have a proper TUI display manager in my leftwm config, so I thought I'd contribute.

This PR changes the clap API to the derive version, which should eliminate some boilerplate code.

Notable changes (to be adjusted/reverted at your discretion):

• switch around some function signatures to use &Path instead of raw &str
• rename --nolog flag to --no-log

Since logind is not considered within it isn't set up properly. This prohibits reboot and shutdown commands from being used and probably has other problems as well.

I liked this project the moment I saw it, and then replaced sddm with it. However, I found a issue preventing KDE Plasma on Wayland from starting. After several days of debugging, I made it :)

The env_variables.rs sets the environment variable XDG_SESSION_ID to an constant of 1, which will cause some permission problems. Since the pam_systemd.so will automatically requests an XDG_SESSION_ID for us and then sets this variable to the correct value, would you mind removing this dummy XDG_SESSION_ID ?

This PR aims to extract a core set of well documented functions from the TUI frontend. This aims to make the internals more stable, debuggable and reusable. There are many things that still need to happen for this PR to be completed.

• [ ] Consider the usability of the API
• [ ] Make internal constants variables accessible from the outside
• [ ] Better documentation
• [ ] Better encapsulation and documentation of the unsafe parts
• [ ] Check root permissions at every public function that needs it
• [ ] Better Error Handling
• [ ] Context for Logging In
  • [ ] Do logging
  • [ ] PAM service
• [ ] More clear environment variable handling
• [ ] Check Health command - [ ] Index all the used external items
• [ ] Port over XSetup.sh file - [ ] Find solution for the custom set environment variables
• [ ] Environment variables / options for different binary locations
• [ ] Custom PAM conversation
  • [ ] Define cross-distro PAM service
  • [ ] Possible integration with SystemD

Hi,

Feel like I'm missing something obvious, but after a trying few different combinations I currently have:

/etc/lemurs/wms/spectrwm

#!/bin/sh

exec spectrwm

Nothing at all in ~/.xinitrc if that makes any difference

When I boot I get the lemurs login prompt with 'spectrwm' at the top, fill in my username and password and it goes to a blank screen. Log appears to show everything running fine up to Run X server, then just says:

[lemurs::ui][ERROR] Starting post-login environment failed

If I disable the service, reboot, login on tty, put exec spectrwm into my ~/.xinitrc and run startx, spectrwm loads as expected.

Any ideas please?

When input username and password, it didn't enter gnome desktop, just stay on greeter page. By the way, this repo is impressive.

let-else statements and similar fresh language syntax features unfortunately inflate the MSRV which makes the project harder to package in most distributions (in my case Void still has Rust 1.64)
