#StackBounty: #drivers #kernel #suspend #20.10 Suspend to RAM not working

Bounty: 150

Ubuntu 20.10 here, first installation upon a newly built system. Everything works perfectly except one thing that’s very important to me: suspend2ram.

If I try to suspend (sleep) via systemctl suspend, the screen blanks out, but nothing else happens, power stays on, fans spinning. At this point, if I press the power button, the monitor turns on, and all is how I left it.

Look at this now. On my system:

$ cat /sys/power/mem_sleep
[s2idle]

Whereas upon a laptop where suspend works, it is:

$ cat /sys/power/mem_sleep
s2idle [deep]

How can I debug the issue? Surely, there is some device which prevents suspend, but how to find it?

What follows are:

  1. inxi dump to show you the system config.
  2. relevant syslog dump.

#StackBounty: #boot #suspend #power-management #20.04 #reboot Ubuntu machine goes into sleep after giving reboot command

Bounty: 100

I am running the latest Ubuntu LTS version: 20.04 on my Dell 7050 Micro.

When I enter the command: reboot and press enter, it does the normal reboot sequence, but most of the time the machine doesn’t come back online, unless I press the power button of the Dell again.

The power button light is fading on/off and I have no idea why this is happening. The only difference is that I see the following line on the screen before it goes into sleep mode or something:

"A suspend job running for…".

What is happening here and how can I fix it?
