Using elogind with GNOME is resulting in eventually being unable to unlock the machine, due to: gdm: Unable to activate session: Timeout was reached but even loginctl over ssh doesn't work at that point: $ loginctl Failed to list sessions: Connection timed out Where do I begin to debug this? Some other log entries: Mar 20 14:33:25 gdm-launch-environment]: AccountsService: Could not get current seat: No such device or address Mar 20 14:33:51 gdm-password]: AccountsService: Could not get current seat: No such device or address Mar 20 22:18:11 gdm: Unable to activate session: Timeout was reached
I should probably mention that I don't have elogind service enabled, due to documentation on wiki stating that it'll auto-activate (as I would expect from dbus activatable services), and one elogind-daemon process is running.
Are there any errors or warning from elogind-daemon in /var/log/messages?
No errors, but why could AccountsService not be getting current seat from sd_session_get_seat call there? I did add a -session optional pam_elogind.so line to /etc/pam.d/gdm-launch-environment Some initial login slowness after boot I did figure out - crng init was slow, so had to add the haveged service to boot runlevel, as unfortunately commonly needed with OpenRC.

GNOME also gets locked, as is done before suspending, and can't unlock afterwards, which is that timeout entry in the log above. loginctl is timing out at this point as well. UPower is also complaining something on lock screen before for automatic suspend, but that was a cleaner failure that didn't actually suspend the system, and logind remaining operational from that - it was a manual suspend call that caused the timeouts to start happening. Suspend worked great on this machine with a systemd install.

This really smells like gdm is too fast. The freeze on suspending sounds like something is blocking. The "what" isn't clear, yet. Could you please start elogind from runlevel "boot" and start gdm by hand from the console instead of doing so automatically? I'd like to know whether the issues go away if gdm is started clearly after elogind has set everything up porperly. Further, if you log into the console without gdm being started, does loginctl show that session? In your log, gdm errors out _before_ the sessions were set up. That's really odd. Do you start gdm directly or via xdm? Apart from that I am currently completely at sea, as I don't use Gnome anywhere and haven't heard of such issues. I follow Dantrell's "Gnome without systemd" thread lightly, to get hints about stuff to improve, but I don't remember something like that having been talked about. Thread: https://forums.gentoo.org/viewtopic-t-1082226.html (Although I guess you know that one better than me, right?) Oh! One last question: Which version of elogind do you use? And one nasty plea: Could you, by any chance, test sys-auth/elogind-241.9999 from my "seden" overlay (via layman) whether that improves things? If it does, there is something wrong with what elogind does for sure. The risk is, of course, that if the situation does not improve for you, that we might end up none the wiser... ...at least for now...
I'll try these things out soon. I have a much simpler patchset to gdm than dantrell, but should be no difference in practice. I keep the pam_systemd.so entry in gdm's pam file, as it's optional with the minus in front, just adding elogind one, while he swaps them out. And I just make gdm configure think it finds systemd from libelogind by passing SYSTEMD_CFLAGS and SYSTEMD_LIBS to it from pkg-config libelogind output (--cflags and --libs accordingly) to not patch and eautoreconf that. I'm not sure the initial login warnings and suspend trouble are related, but we'll see from testing soon I suppose. I have version 241.1 on there. loginctl does show all sessions until it isn't hung from partial suspend. I start with xdm and it's all wayland, no X besides Xwayland. There is nothing besides xdm to start gdm with OpenRC. The gdm used gnome-shell gets shut down too after login and it doesn't show up as a session in loginctl until I go back to the gdm VT (with wayland gdm reaps the gnome-shell and gnome-session stuff away to save memory now when the VT isn't active after a timeout == soon after logged in; and comes back when doing "Switch user" or manually changing back to VT7).
Hmmm... * When I look into the tree, gnome-base/gdm has elogind support now. Are you sure that patching is still necessary and is not doing any damage? * Do you have "elogind" USE flag enabled globally and both "systemd" and "consolekit" disabled? elogind does not do anything spectacular on suspending/hibernating the system. 1. open /sys/power/state and fail if this is not possible 2. Determine hibernation location when hibernating (aka which swap to write to) 3. Write configured "HibernateMode" into /sys/power/disk when hibernating 4. Execute all scripts from SYSTEM_SLEEP_PATH (defaults to /lib64/elogind/system-sleep) and fail on errors if "AllowSuspendInterrupts" is set to yes 5. Write "SuspendState" or "HibernateState" to /sys/power/state If, from here on, suspension hangs and you have to kill elogind, than someone has a thumb on /sys/power/state and elogind is simply waiting for the write to finish. (Which normally is when the system is resumed.) Is there anything running which might race with elogind to send the system to sleep? Or hindering it to do so? What happens if you do $ sudo echo "mem" > /sys/power/state manually?
The only patching I'm doing in gdm is to add a -session optional pam_elogind.so line to /etc/pam.d/gdm-launch-environment file, alongside the existing -session optional pam_systemd.so line, otherwise the gdm launch environment doesn't properly talk to elogind with its custom pam config, presumably. The rest is done via configure precious arguments. That system has never had systemd nor consolekit installed. It's a fresh test install on a separate disk that went straight towards elogind. I have added USE="elogind -consolekit" to GNOME profiles some time ago and that box has been handled with emerge --changed-use.
Created attachment 570912 [details] strace output while suspending I don't see anything else accessing /sys/power/state, other than elogind-daemon, at the time of the stuckedness as per lsof. Attached is a strace output from trying to suspend via gnome-shell menu. Excerpts from IRC about it (Sven disconnected with timeout at some point): <leio> first half of it is from opening gnome-shell top right menu <leio> it probably queries some CanSuspend and whatever stuff <leio> and then it ends once it gets stuck from suspend action <leio> computer stays on, screen is blanked <leio> if I move touchpad, gnome unlock screen is visible <leio> and I can try to unlock <leio> but because logind is stuck, it doesn't work <leio> I've heard success reports with this gnome elogind stuff from others, however; just having problems on my own test rig <leio> though only one explicit success report regarding suspending; another I talked to just doesn't have a working suspend overall <leio> that strace probably quite revealing in which thing to try next? The in-use proc/dev thing? <leio> at least ssh'ing in as root for extra debugging works after a long wait :) <leio> at least lsof /sys/power/state only claims elogind-daemon having it open (and stuck)
I have thought about this, and I think we are getting nearer. * The only difference between elogind suspending and manually writing "mem" into /sys/power/state is elogind sending "PrepareForSleep" to all registered processes. * After a long wait, which is inconsistent in length between attempts, the machine suspends. * The delay is during "Freezing user processes" My guess is, that at least one process is stuck in whatever it does as a reaction on the "PrepareForSleep" signal. That process is either catching (and then delaying) the freeze signal (SIGSTOP I guess...) or is locked in Disk Wait. As you can ssh into the machine during that delay, could you please have a look with 'ps' and/or [h]top which process that might be? If it is Disk Wait, it will have a D+ state. elogind doesn't count, as it waits for its write to /sys/power/state to return. But I hope the process is actively delaying the freeze, meaning it'll generate CPU usage in [h]top and/or IO in iotop. My hope comes from D+ being absolutely uninterruptible.
As it works with systemd, but elogind isn't doing anything different than systemd, the reason might be a process that tries to talk to systemd manager when receiving the PrepareForSleep signal and then simply hangs until it times out. If we can find out which process that is, we can patch the package and send a fix upstream.
For me, this only happens when trying to suspend from a Plasma wayland session, either from the interface, or via ssh with loginctl suspend. Everything seems to be normal under X using both methods. Please let me know if there is any additional info I can provide.

Yep same here (but GNOME Wayland). Under X everything works perfectly. I'm also on dedicated NVIDIA GPU (RTX 4090)

Can't 'loginctl suspend' from a Wayland session, causes elogind to hang. As noted in another comment, if I kill -9 elogind, the suspend will suddenly complete. On the console it works. GPU is an AMD ATI Mobility Radeon HD 5730.

Tested this with X and KDE, 'loginctl suspend' works as expected. So, the problem does appear to be Wayland/elogind related.
