wake on lan on Ubuntu 16.04 (KDE Neon)
Posted: Thu Oct 05, 2017 5:21 pm
hello
I've been seting up wolsleep/wolwake on my machines and so far so good it's working fine now.
I'm using Kde Neon 16.04 xenial (Ubuntu 16.04) and I faced some problems
1/I had to switch from SysV to systemd scripts to get correct daemons autostart at boot ...
2/using the default wolsleep script gave me a lot of problems
"echo mem > /sys/power/state"
effectively put the system to sleep but then wolwake leaves the machine in an unusable state ..
it seems to be specific to Ubuntu.I found a lot of discussions of people having problems with suspend/hibernate with ubuntu 16.04.
on the machines I have this :
>more /sys/power/state : freeze standby mem disk
>more /sys/power/mem_sleep : s2idle shallow [deep]
I tried several combinations like sending "freeze" or "disk" to /sys/power/state but non worked .. the machine just doesn't wake up
so finally I just replaced wolsleep with a brute force "/sbin/shutdown" command.
I don't understand that much of the power state business so if someone got this to work on a 16.04 system please let me know...
