Bug Description

On a default Bionic Desktop installation, gnome-software starts early and slows down session startup. In the bootchart attached, it overlaps with gnome-shell startup which is also resource intensive.
With gnome-software delayed gnome-shell starts 2 seconds faster.

gnome-software service startup should be delayed if it cannot be stop completely.

[Test Case]
1. Login to the default session
2. After 60 seconds confirm their is a gnome-software process running

Expected result:
The gnome-software process should be running in the background allowing to search for apps in the gnome-shell search

Observed result:
Works as expected (i.e. only looking for regressions).

[Regression Potential]
Very low, the change is very simple and well known method to delay autostart. If it doesn't actually start, it will be dbus activated on the first attempt to search which would just cause a slight delay in getting results

in this bootchart the system is quiet after 49s if gnome-software service is delayed by 1 minute.

Thanks, that makes sense I think, you tested adding an X-GNOME-Autostart-Delay key to the autostart desktop right and that worked?

Jean-Baptiste Lallement (jibel) wrote :

Yes, this is the desktop file I used:
[Desktop Entry]
Name=GNOME Software
Exec=/usr/bin/gnome-software --gapplication-service

I tried with 60s but it can probably be more. The drawback is that gnome-software is used as a search provider and package search won't be available until it's running.

Just for clarity, was your test done on a computer with a traditional hard drive or solid state drive?

I just saw that kalev proposed turning it off altogether on the Fedora live CD

...maybe we should?

Will Cooke (willcooke) wrote :

+1 - I dont think there is a huge benefit to have it auto-start in the live session and starting the live session quicker seems more useful.

Jeremy Bicha (jbicha) wrote :

Disabling the gnome-software autostart for our live image sounds like a great idea to me.

+1, I filed a separate report in bug 1758920.

right, then we don't need to do this

We still do. That's 2 different things:
- This bug is to improve the session startup time of an installed system
- Bug 1758920 is to lighten the load on the live session. I don't think we want to disable the service on an installed system.

ok, I thought this was about a live session too.

It being about the installed system changes my assessment a bit. In particular, I think it should be discussed with upstream before we press ahead with changing anything about this bug in Ubuntu, whereas the live environment is more special so it's often more okay to do hacks there.

So, please file a bug upstream or come to #gnome-software or post on the ML for a chat.

Assigning myself as there doesn't seem to be a clear decision on if we want this or not (I have not strong opinion either way).

The autostart delay feature never made it upstream [1], so there's not really anything worth discussing with the GNOME Software developers. I figure we just upload it for Ubuntu and then it's in the queue of things to discuss at some point.

@jibel - can you update the bug description to be suitable for SRU?

This bug is missing SRU information in its description. Could you add a test case and a regression potential analysis? I'll review it then ASAP. Thank you!
