Kernel freeze after hibernation (not nvidia)

General system Kernel, boot, graphics & hardware

hi,

I’ve a laptop (https://0x0.st/X68H.txt) with intel graphic card. It works without issue apart when :

  • I connect a screen on HDMI and a screen on display port
  • i leave the computer idle until it goes to sleep (at least screen sgut down alone)

when i come back, event the capslok key’s led is unresponsive, leaving me no other choice than reboot.

sudo journalctl -b -1

Doesn’t seem to give any error before shutdown.

How can I investigate this issue ?

Check if the device is accessible via network, try to ssh to it and see if that works.

This is a professional laptop, I’m afraid to activate sshd.

sudo systemctl status sshd.service
○ sshd.service - OpenSSH Daemon
     Loaded: loaded (/usr/lib/systemd/system/sshd.service; disabled; preset: disabled)
     Active: inactive (dead)

when i try to connect to my ip i got

ssh 192.168.1.137
ssh: connect to host 192.168.1.137 port 22: Connection refused

rather quickly (an unknown ip gives me a timeout)

if the idea is to check health the laptop it may be enough ?

othewise if no other way to instigate, i will activate it.

If you don’t enable sshd you can’t do that test.

I’ve enabled it, I will try at the end of the day.

Some more information.

I’m using i3:
if I use

  • Suspend=systemctl suspend
  • Hibernate=systemctl hibernate

Both commands work, and I get back my machine up. Note that hibernate takes 85s to hibernate and 95s to wake up 0__°. I may not have waited so long in front of a black screen before

waiting now for my computer to idle, I’ll be back in 20 minutes

zzZZzz

Screen goes black, while I was connected via ssh.

in journalctl -f I can see some autorandr messages

Then tried to awake the computer … to no avail, waiting more than 2 minutes

ssh connection returns no route to host

if you hibernate and that works, network devices are off and therefore not reachable. But you can test if you wake your pc if waking works and just your screen stays black. In this case you can do further tests while screen is black.

Well, when idle, the ssh connection is closed, and trying to create a new connection returns no route to host
don’t know where else to get logs.
Thanks for your help kmonster :slight_smile:
