Rootston freezes on ssh log out

After a couple of minutes of no activity, the lock screen will freeze, and its contents will not get updated no matter what.

The situation can be fixed by issuing systemctl restart phosh.

last lines of dmesg dmesg:

[ 4807.890960] etnaviv-gpu 130000.gpu: genpd_runtime_suspend()
[ 4828.364971] etnaviv-gpu 130000.gpu: genpd_runtime_resume()
[ 4828.900932] etnaviv-gpu 130000.gpu: genpd_runtime_suspend()

I can't reproduce this. I've been running previous versions of wlroots/phosh for several days on the nitrogen6 and I've been using the current version for several hours. Can you debug further?

I have seen issues where wlroots would freeze when closing out of the ssh session that started it. Could that be your issue (I've not debugged this further yet since it's started during boot).

$ uptime
14:07:12 up 1 day, 23:13,  2 users,  load average: 0.25, 0.10, 0.03

Lockscreen still responsive.

Steps to reproduce:

$ ssh nitrogenboard
$ systemctl restart phosh
$ exit

Relevant log entries:

Jul 20 14:51:58 pureos systemd-logind[362]: Removed session 26.

with that wlroots suspends input and output devices.

changed title from Lock screen freezes on imx6 to Rootston freezes on ssh log out

I've changed the bug title so we only track one issue. If there are other freeze causes let's open separate bugs. !12 (closed) shows that the device pause is indeed the cause of the problem.

changed the description

See https://github.com/systemd/systemd/issues/9674

mentioned in issue virtboard#15

mentioned in merge request !35 (closed)

We should check what happens when we use pam_systemd.so in the pam stack.

mentioned in issue #18 (closed)

I've not seen this since ages so it seems to be fixed with newer systemd, o.k. to close?

I haven't seen it either, so I'll close. We can reopen when we notice it again.

Just confirming that it occurs following an scp into the device over Ethernet (see phosh#70 (closed)):
