Ubuntu suspend doesn't work

uz flag

Notebook HP Omen 15-en00xx. AMD 7 4800H/ RTX2060, Win10 + Ubuntu 21.04, nvidia driver-460, external monitor.

Steps: Power off -> suspend -> 5-7 sec display is black and login form. After logging is the clean system without early opened programs.

I remember similar problem on previous laptop - win10 and ubuntu 18. In that case Ubuntu didn't have a suspend mode in the list under "power off" menu and I found solution related to disabling hybernate mode in Windows (I can be incorrect here). I want to try that solution but can't find it now.

Just to confirm: when you resume from suspend, all of your applications are closed. This is the problem you want to fix, yes?

@matigo Thank you for the answer. There are 2 related (I suppose) problems - 1) the laptop don't really sleep in "suspend" mode (coolers work) and "wake up" (reload) after 5-7 sec independently. 2) All programs are closed after wake up from this broken suspend mode.

Get more info with `sudo journalctl --since="-5 minutes"` within 4 minutes of a suspend attempt

Does `free` show any swap space?

I fix this problem in two actions:

  1. I upgrade bios from F.7 to F.15 (from win10).
  2. After restarting Ubuntu lost RTX video adapter (the external monitor doesn't work with AMD in my case). Also About -> Graphics section showed only AMD video adapter. I installed Nvidia driver 470 instead of 460 with enrolling changes in grub. Now suspend mode works perfectly.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
