LOOOOOOONNNNG login times with system-monitor enabled - Ubuntu

[BloodyIron]

I'm running gnome-shell 3.30.2 with Ubuntu 18.10

Whenever I have this extension enabled, randomly my login will take FOREVE. Or, more specifically, anywhere from like 15 seconds to 1.5 minutes+.

I have a beefy rig, ryzen 5 2600 + Samsung 970 Evo Plus, so this kind of a delay is not okay.

Not sure where to begin giving info on my setup here, since I'm new to gnome-plugins. But the issue for sure goes away when I disable just this one extension.

I'd like to help to get this sorted, because I quite like this extension otherwise.

I did experience similar login times, but I did not link them to this extension. I can't test it myself currently, because it is broken on 3.32.

But the issue for sure goes away when I disable just this one extension.

Try the opposite: Disable all extensions and enable only this one. Can you still reproduce the issue? If no, it may be another extension or multiple ones interacting in a bad way.

[BloodyIron]

I actually went through previously and toggled them all off then back on individually to try and reproduce the issue. The issue didn't show up until I turned system-monitor on. So I'm confident that it is the cause.

[BloodyIron]

So is this abandoned? Feeling like it...

This is a duplicate of issue #511, which has had a fix merged. Assuming people are happy with master, I'll probably push up an official release in the next week or so.

[BloodyIron]

@chrisspen how is this a duplicate of support for 3.32 if the issue I'm reporting was on an earlier version of gnome?

[chrisspen]

@BloodyIron The problem effects other versions than just 3.32...

[BloodyIron]

So then why is this closed? The "dupe" ticket is about version support, not performance...

[RavanH]

I agree, this should not be closed. I am seeing this behavior on Ubuntu 19.04 on Xorg session but with logout, not with login. Very weird... the problem disappears completely (logout time dropping from over 40 seconds to less than 4) when system-monitor is disabled.

Wayland session does not suffer this issue except right after having run an Xorg session (with loooong logout time) and then starting a Wayland session. Then I get a looooong login time: more than one minute where it usually is less than 10 seconds to a full and responsive desktop. Even more weird...

[chrisspen]

@RavanH Which version of the extension are you using?

[RavanH]

@chrisspen Where do I find the version?

[chrisspen]

@RavanH Did you install from the extensions.gnome.org website or from github?

[RavanH]

The one from extensions.gnome.org does not work on Ubuntu 19.04 so I've replaced the files with the ones from Github :)

[chrisspen]

That's what I was getting at thanks.

[BloodyIron]

I'd love to retest, but 3.32 is not on the extensions page and I'm on 19.04 (Ubuntu) which is gnome-session 3.32.

[chrisspen]

@BloodyIron You'd have to install from github as explained in the readme. By the time it's on the extensions page, it's too late to test.

[RavanH]

Hi @chrisspen I've been running the extension on an Xorg session a while now and it's a very elusive issue. I noticed that the long logout time usually occurs when I have just de/activated the system-monitor extension. Also happend a few times on login but then there is also an error message from my hplip-gui about a missing system tray (it wants to add a HP logo with an options menu there) ... so maybe this is related? Or maybe just a secondary result of the long login time, not sure.

[RossLYoung]

Ignore that. The problem is still there.
I was experiencing this as well. I had no idea the login delay was caused by this extension, so a huge thanks for pointing it out.
I also couldn't start the system monitor from the menu #474
When I changed my system monitor from the snap version to the apt version, the login delay has gone.
#474 (comment)
It has only been 48 hours, but there's been no login delay so far.
