Power suspend not working

I am working on Void Linux with XFCE4 which is updated and otherwise working very well.

Earlier, when I pressed "suspend" button from XFCE4 log-out menu, the computer would suspend properly - screen goes blank, no disk activity and power button used change from ON to blinking state. Then on pressing spacebar, it would wake up, power button would become ON again and desktop would be restored on screen.

Recently, however, there is a problem. On pressing "suspend" button, the screen goes blank but disk activity continues and power button remains ON (not change to blinking). Moreover, on pressing spacebar, desktop is not restored and I have press to the restart button or switch off the computer and then switch on again.

Memory and swap status on my desktop can be seen from output of `free` command:

    $ free -h
                   total        used        free      shared  buff/cache   available
    Mem:           3.8Gi       1.1Gi       2.2Gi        77Mi       569Mi       2.4Gi
    Swap:           11Gi          0B        11Gi

I tried to search the internet but found mainly pages which describe solutions involving `systemd`, but Void Linux has `runit`.

Since the computer goes off, I can check output of command: `dmesg | tail`

Where could be the problem and how can it be solved? Thanks for your help.

I also tried `zzz` command:

`zzz -n` : gives proper response- sleep for a few seconds

`zzz -z` : produces result as described in my question above - blank screen but power still on, disk still working and not waking up on pressing spacebar. I have to restart the computer.

I am not sure if my post is of any help.

With my Debian one, hibernate and suspend are quite unreliable. Every time after system upgrade (or whatever), I need to accept any unexpected (somewhere between perfect and system freeze, kernel panic). I do not have major trouble other than these power related issue.

Your system may be back in good health after next update.

cheers

Thanks for your answer. Contrary to your experience, I hardly ever have problem with my Debian Stable installation on this same desktop. However, I have been using suspend only, not hibernate. You have not mentioned if your Debian installation is of stable/testing/unstable branch.

Hya,

My Debian is testing.

Trouble is with one of my laptops, but not all of them. Desktop is less troublesome, yes, I agree.
Post #2 is with the troubled one. I stopped troubleshooting, because is is unpredictable.

I hope situation goes better with you.

cheers

rng, please have a look at the journal from the exact time you initiate the suspend.
Finding journal entries from that time will be tricky; have a look at

man journalctl

I suspect you need to set the '--since' option to the correct timedate.

Also

systemd-inhibit

I suspect you are using the xfce4-power-manager to manage screen blanking, suspend and hibernate? Which one of those three is problematic for you? You say suspend, but the behavior ("on pressing spacebar, it would wake up") sounds more like simple screen blanking.
Please do have a look at xfce4-power-manager settings how things are set up. Along with the other output I requested.

Thanks for your suggestions. I had clarified in my post that Void Linux does not have systemd as the init system. It has runit. There are no "journalctl" etc commands here.

I read somewhere that in Debian "testing" version, errors take longer to be corrected as compared with Debian "unstable" version, where corrected packages are updated promptly. Debian Stable has no errors!

Update: It has started working, possibly as a result of update. Updates were being applied daily but earlier it was not working despite updates.
