Getting Guix to shutdown my laptop properly with Sway and no DE

Getting Guix to shutdown my laptop properly with Sway and no DE

[danclm--- via]

Hello everyone!

My T420 with Guix (no DE, only SDDM + Elogind + Sway) hangs during shutdown after running loginctl poweroff/reboot or /sbin/shutdown /sbin/reboot. It just sits there and only resolution is hard poweroff. It happens often.

Is there something that I'm missing in my system.scm?

Hi,

I don't have any suggestions for you, I just wish to add that I am also
having the same issue, and I use Sway and Elogind (but no display
manager). I have been dealing with it by hard powering off also, but it
would be nice to have a proper solution :)

Hi Robby, 
thanks for your response.

Do you mind sharing your config? 
I never managed on Guix to autologin and automatically start Sway without a display manager.

In case this is relevant I am experiencing a similar issue in a VM 
running kmscon. I /think/ it happens when I reconfigure my system in a 
way that changes the services running on the OS (maybe the user services 
too, I don't run any at the moment) but this is based on anecdotal 
observations, I haven't found time to thoroughly test or root-cause 
anything. So it might be a different issue with the same symptom, or 
Sway might not be a relevant detail (or both).

Hi Daniele,

I actually don't have auto login / auto start Sway - I just login with a
TTY, and then I use `herd start sway` with a little guix home service
that I wrote:

(shepherd-service
  (documentation "SwayWM")
  (provision '(sway))
  (requirement '(dbus))
  (respawn? #f)
  (auto-start? #f)
  (start #~(make-forkexec-constructor
            (list #$(file-append (specification->package "dbus") "/bin/dbus-run-session") "sway")
            #:log-file (string-append #$log-dir "/swaywm.log")))
  (stop #~(make-system-destructor
           (string-join (list #$(file-append (specification->package "sway") "/bin/swaymsg")
                              "exit")))))

This isn't perfect (I use the system sway binary, but I use swaymsg from
my home profile - which means they can be different package version; and
herd stop sway doesn't work), but it's been good enough for me to not
care to fix.

Hello,

I have the same (or extremely similiar) issue. It seems that it is because of
shepherd. The system seems to work alright, although can’t communicate with it
at all. For some reason it hangs. Tried looking for logs for the program, sadly
I’m extremely new to Gnu Guix and still stuck here. :(

(Writing this out with an idea that it might maybe help)

Re: Getting Guix to shutdown my laptop properly with Sway and no DE

[Etienne B. Roesch]

Hi,

I think I have been having the same problem for a while, using standalone
guix system on a desktop. It seems to sort itself out after a pull and
system reconfigure, but then it breaks again: The countdown does not start
and hangs. I have to hard stop the desktop, which is fine but not exactly
what should be happening.

Same issue here, quite often. But I have no idea what's happening and no

bug#65178: Shepherd hangs (was: Getting Guix to shutdown my laptop properly with Sway and no DE)

[Hilton Chain via Bug reports for GNU Guix]

Hello!

I have experienced many instances of Shepherd hanging through my use
of Guix, though I don't have a clear record of when it first happened.

These days I have seen a few reports on the subject.  With a quick
search of recent bug reports, I can't find any related, only to find
this thread [1] on help-guix.  So I'll start a bug report here, but I
don't know how to debug Shepherd and I haven't found a way to
reproduce it stably.

I'm not sure if Shepherd hangs at usual, but most of the time I find
it already hanging is when doing a reconfiguration.  The
reconfiguration becomes unresponsive and it won't accept a ^C, herd
actions also hang.  This usually happens with home reconfiguration,
but I can remember once with system reconfiguration when adding and
deleting some services in the configuration file.

I'm not sure how Shepherd hangs either, because in the latter case
(system one) I can still see logs indicating that it's trying to
respawn a process I killed manually, even though that's just a output
and no processes are actually spawned.

And as shown in [1], there are also cases where Shepherd hangs at some
point in the halting process, usually after syslogd has been
terminated but before term-tty*.

(The termination message indicates that Shepherd is still functional,
and no logs after that point shows that that's a real action, but
because of this I can't know anything happened further either.  After
that I'm still able to switch ttys so I assume term-tty* are alive.)

Although I don't know how they are related, I have linked my
configurations below:

<https://codeberg.org/hako/Testament/src/branch/trunk/dorphine-system.scm>

Today I encountered the home reconfiguration issue.  The behavior is
similar to <https://issues.guix.gnu.org/54919>.

Ending part of output for the hanging reconfiguration:

And today Shepherd hung after starting a service [1], the service
itself started successfully (process started, logs available):
--8<---------------cut here---------------start------------->8---
$ sudo herd enable cloudflare-tunnel && sudo herd start cloudflare-tunnel
Enabled service cloudflare-tunnel.

I’m assuming this is shepherd 0.10.2, right?

Is any of the services you’re using doing “non-standard things” such as
using constructors/destructors other than those provided by shepherd
(‘make-forkexec-constructor’ et al.)?

Is it reproducible, and do you think you could come up with a reduce
test case (for example by removing services from the config until you
reach the minimum)?

Thanks,
Ludo’.

No, I'm unaware of such things.

I still don't know which condition triggers it, so I can't make a test
case.

It's unreproducible.  And I don't think it's really related to the
config, since Shepherd won't hang when rebooting to a system
generation which made it hanging at reconfiguration before.

It might be related to bug#65419 ([Shepherd] Non-reponding service
control fiber) you have reported, since there's similar behavior that
`herd status nscd' still works when Shepherd hangs.
