A doubt about suspension...

English Hardware
#1

It was the very first time I tried suspension mode on my laptop, and actually it was kind of a mouse-click accident…

I had just Firefox running, but with 2 tabs, one of them was youtube playing a video.

I hit suspension and it did. Then woke it up and I saw youtube video resumed playing from where it was “paused”. I just had to reconnect to my wifi AP.

This will probably sound stupid, but it’s the first time I see suspension in action, and I didn’t want to try it since it didn’t work well for my friend. Are there usually some consequences after suspending? Could Flash Player or another plugin or system files get corrupted or the like?

Thanks beforehand.

No

Some hardware suspends just fine some does not. If not sometimes work arounds can be found sometimes not.

The thing is there is a large variation of how laptops are made. Some work better with Linux and some just refuse to. Mostly it is major differences the BIOS or UEFI code from standards. In fact it is not uncommon to have problems installing generic Windows or having suspend function work there also and you need to install special drivers and patches to make it work. Most users don’t see this because Windows comes pre-installed. Since the computer makers don’t care about Linux you don’t get Linux drivers to fix their nonstandard hardware.

So do you think I’ll be fine? Even if I hit suspend while power plugged? Possible future software issues at long term?

Mine is a Dell Inspiron 1520 with software specs on signature, my friend’s is an Acer Aspire 3680 with 13.1, but he said suspension wasn’t working for him on Gnome since previous releases, but on KDE it works fine…

Why not?

As said, suspension/hibernation may not work on some machines or have some quirks. On yours it seems
you have to restart network, so you are good.

Some programs may be “bewildered” when they awake. It is typical for those working with network,
downloading or serving something, because obviously, the packets they expect the next second from
the network never arrive (they did maybe days ago, instead, on another life - so to speak).

I have been using hibernation on all my machines for about a decade, mostly working perfect.

I have to “reconnect” network maybe because I have auto-connect disabled in network manager, I forgot to mention that.

My friend’s rig has always worked suspension/hibernation on KDE, but not on Gnome in late openSUSE releases.

And I hit suspension, not hibernation (of which I heard there’s a bug on 12.3 by the way, concerning the hibernation “screen”, preventing it’s correct execution, and fixed by editing some config file…).

But have you hibernated/suspended while a Youtube video opened, or some other “nasty” process?

I really hate uncertainties…

I often initiate hibernation from CLI command “pm-hibernate”.

No idea about that. I have no problem in 12.3 nor 13.1. As this is a desktop, I use hibernation, not
suspend (pointless: no battery). My laptop runs 11.4 evergreen and there is a problem with suspend
(not with hibernate), mouse does not recover properly. 13.1 works correctly, I believe.

Mind you: suspend often has problems on the same machine as hibernate doesn’t. Somehow it is weaker.

I have hibernated while running donkey things :slight_smile:

Or downloading an openSUSE distro.

Or in the middle of heavy processing, like converting a bunch of videos, or building a kernel.

But not with youtube running a video, AFAIR.
