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

Hi,

Thank you for this report. I spend quite some time on trying to find the solution to this. GDM is doing some special stuff normally to make sure gnome-session works fine.

I have been able to identify some points. These are more reminders for me when I continue working on this.

1. We really should be setting XDG_SESSION_TYPE=x11/wayland/tty depending on the post_login type.
2. We should set MOZ_ENABLE_WAYLAND=1 QT_QPA_PLATFORM=wayland for Wayland sessions.
3. Some of the error logging in the post_login/mod.rs file is not really helping.
4. You need to install libpam-dev on Ubuntu to use this project.
5. You can log gnome-session with the --debug flag.
6. The debug output shows that the display is not properly set. Using DISPLAY=:1 does not resolve the issue. In fact the documentation stated that gnome-session does this itself.
7. Starting a gnome-session from the tty is quite difficult.

To be honest, I am having many problems with setting up a good testing environment.

I will follow up soon.

[kmephistoh]

If you want start a gnome-sesion from available tty, this arch wiki may helpfull arch gnome

XDG_SESSION_TYPE=wayland dbus-run-session gnome-session or gnome-shell --wayland

➜  wayland pwd
/etc/lemurs/wayland
➜  wayland grep -v '^#' ubuntu
exec env GNOME_SHELL_SESSION_MODE=ubuntu XDG_SESSION_TYPE=wayland MOZ_ENABLE_WAYLAND=1 QT_QPA_PLATFORM=wayland dbus-run-session /usr/bin/gnome-session --session=ubuntu
➜  wayland ls
sway  ubuntu

The above config still didn't work, but it works if you execute it from tty. when enable --debug, the log screen disappear too fast, can't find a way to review the debug log

[coastalwhite]

I think this is a problem with gnome-session in general. I had someone message me about the same problem for the X11 gnome-session. I didn't test this yet, but according to the arch wiki somewhere. GDM puts the Xauthority file somewhere else than the home directory. This might well be the problem.

There is also a possibility that it has something to do with the rights given to the Xauthority file in the home directory.

[coastalwhite]

The problem seems to be exclusively with Ubuntu. I tested it with a fresh arch setup and gnome and everything seems to work fine. I will investigate more later.

[coastalwhite]

Okay. I have tracked the issue down. It turns out that the PAM services are very different between Ubuntu and other distributions. Now, I just need to find a fix that seems reasonable.

[Relwi]

I have the same problem and logs as @kmephistoh, but instead Ubuntu I'm trying to launch labwc in Arch Linux. I have the wayland folder created and the labwc file with the script, I didn't change anything else.

labwc

#! /bin/sh 
exec labwc

If I change to another tty and run the command labwc it starts correctly.

[coastalwhite]

After looking at this problem some more. I am surprised logging in with lemurs works at all on Ubuntu. The current PAM configuration is totally unsuited for Ubuntu. I will see what I can do about this.

[coastalwhite]

Is there any chance you can both try again? It works now on my side, but your issues may be different?

[Relwi]

Unfortunately it still doesn't work for me, here is the logs, btw, is there the possibility that I'm missing some packages? Update: I'm using Nushell as my primary bash

    Add `shell_login_flag` option in config (#129)

Hi, I pull the latest main branch(no dev branch exist), at lemurs.log: [INFO lemurs::auth] Authentication failed for 'mephisto'. Reason: Failed to open a PAM session at auth.log: Mar 7 13:50:26 workpc lemurs: pam_loginuid(lemurs:session): Error writing /proc/self/loginuid: Operation not permitted Mar 7 13:50:26 workpc lemurs: pam_loginuid(lemurs:session): set_loginuid failed By the way

1. if lemurs.log would add timestamp info at the beginning of each line, that may helpful for multi times test.
2. libpam-dev has updated to libpam0g-dev at Ubuntu 22.10.

Hey @Relwi, you were probably experiencing the same issue as #131. After resolving that issue, I can now run LabWC just fine. (Where it didn't before for me).

Thank you a lot for this debugging. I am talking to the maintainer of the pam crate because there seem to be some problems on that side. I will come back to this.

[Relwi]

Yep, I recently updated the package and is working now, thanks!

Speaking of pam, I think you should include libpam0g-dev for building at Ubuntu 22.04
