Very odd log. I don’t know where shell script is being used, all 66 service scripts are using execline. What does just running ‘66-intree -g’ give?

This whole thing sounds weird. dbus crashing or not shouldn't have anything to do with your devices. That sounds more like a udev thing.

Edit: Hmm well on second thought how are you even starting xorg if there's no dbus? Shouldn't elogind be down as well? I guess that might have something to do with it (strange xorg permissions or something).

Well, the only thing both my desktop and laptop have in common besides this error, which manifests in dbus(+connmand+other services depending on dbus) not starting initially and input devices being unresponsive under Xorg when that happens, is that I migrated to 66 on both of them from s6 (and, in the case of my desktop, reverted back).

If there is a way to at least better debug this, I'd appreciate the information. Like, why is dbus not starting? What caused the SIGTERM? I'm using VERBOSITY=4 in /etc/66/init.conf, but I feel it's not enough.

For now, my laptop currently decided to start dbus and dbus-related services on boot. But I wouldn't bet it would do that on next boot.

Edit: Sorry, forgot to attach the 66-intree -g output: https://paste.artixlinux.org/8e12dabf

I will try to reboot, see what happens and run this again.

I don't have a good conceptual grasp on 66 (honestly, it's a bit confusing to me), but I suspect there's something strange/subtle with the way it actually starts trees. What is unusual about the dbus daemon is that it actually leverages s6-rc's notification readiness feature (by using the --print-pid option). Perhaps using that somehow does weird things when the trees start (a race condition)? I don't really know the 66 service syntax but maybe you could try removing that option/feature and seeing if you still get problems.

Looking at the 66-intree output, I don't see anything that would cause atomic service issue, as the longshots appear to be running.

Just to report that rebooting my laptop messed it up again. I tried powering it down then powering back on, rebooting with loginctl reboot, now dbus refuses to start and Xorg has unresponsive input. Here are the latest logs:

66-inservice -g dbus: https://paste.artixlinux.org/4a22f4c1

66-intree -g: https://paste.artixlinux.org/f3493433

/run/66/log/0/current: https://paste.artixlinux.org/6ac1746e

/run/66/log/udevd/current: https://paste.artixlinux.org/998d4746 - hmmm, "maximum number (16) of children reached"? And "no db file to read /run/udev/data/+drivers:jmb38x_ms: No such file or directory" (and so on).

@Dudemanguy: I can try to do that.

I've enabled all the services you have listed in 66-intree and rebooted and I don't get any issue :\

Maybe the problem is with udevd?
I don't know, udevd is working fine for me. Looking at your log for udev seems that it can't find some files.

Edit: I've tried to use s6's udev and udevadm script, atleast the executable part and on my system it fails to even work. Though both systems run udevd -D and udevadm is near identical except 66's udevadm runs some db cleanup before starting population

Did you try 66-tree -RD default and 66-tree -ncE default and re-add services again?

Yes, I did that earlier today (my post before that one).

@Dudemanguy I tried to omit the --print-pid, 66-update default and reboot, but no change unfortunately.

One thing to try, remove @notify line in dbus and do 66-enable -F dbus and see if that works. As dude told me, usually sv-listens1 iirc, deals with s6's log

Also note, if you change something locally, do force update in the compiled db, you need the -F service to force it to recompile the service file. And if you update a service file, it is best to put it in /etc/suite66/service esp if something works for your system, in case I update a service file and your changes would be overwritten. Placing in /etc/suite66/service protects the service file and 66 looks there first, then /etc/66/service

That's normal. udevd's debug output is extremely noisy.

Did you also remove the "notify" line in the file? I believe that is related.

Ok, I tried that and even if I get the message "all-Runtime: ... some service failed to start correctly" before the login screen, when I start Xorg, everything seems to be working fine, and 66-intree -g shows all services as "up". I tried both rebooting with loginctl reboot and turning the laptop off and then on, and everything worked as described. Hopefully that solved it. :/

In '66-intree -g' look for service(#, enabled...) if a longtype has a 0 in place of # that is the one that caused crash as it isn't running.
