Strongly delayed desktop setup after login

Since an update I did last night before I wanted to go to sleep, the plasma desktop takes a very long time to build up, i.e. the time from logging in is now significantly longer (splash-screen).

Find someone to blame by:

As far as I can do anything at all with this list: are these values normal, or does user@1000.service take too much time?

no, looks fine actually :thinking:

I mean, mine user@1000.service is 100ms, but 1s is not…THAT much, in all scheme of things combined

Are all boots longer, or just one after update?

What if you disabled the splash-screen?

All reboots, whether with LTS kernel or current kernel.

How can I do that? I will try that this afternoon, now I have to go away first.

In the System Settings, search splash screen.
It should be somewhere under startup and shutdown if I remember correctly.
Choose none.

No improvement without spash-screen. Same duration until the desktop. The desktop is also no longer displayed animated, but abruptly. Compositor is running though.

For a usefull report use

systemd-analyze critical-chain
[vidar@arch-pc ~]$ systemd-analyze critical-chain

What you find as a delay is not covered by systemd-analyze reports.
Maybe there is something usefull in the user session

systemd-analyze --user critical-chain

Next, you can just blame Plasma :man_shrugging:

Also check journal for error messages

Not sure, but could looking into what got updated give some clue?

I already checked for the latest stuff, but I couldn’t find anything there that would have given me a clue. Yesterday evening, I honestly did not pay much attention to what came in … bad mistake, I know …

You could look at /var/log/pacman.log.

Hm …, in the meantime I have here now again the normal state. Strange … KDE surprise egg?

Here’s mine on KDE Plasma if you want to compare?

Here is mine for KDE Plasma:

 systemd-analyze blame
21.132s dev-sda2.device
18.331s systemd-remount-fs.service
 2.737s systemd-journal-flush.service
 2.512s accounts-daemon.service
 2.357s udisks2.service

Do you think it is taking a long time due to the HD?

If I am not mistaken, the delay was between the login screen and the desktop showing up. The startup time of the systemd services will not have any bearing on that as mentioned also above by @petsam.


The system runs on SSD for me, only the configs in /home are on a HDD. But anyway, I have not changed anything in the meantime.
