[SOLVED] Long plasmashell start times.

EDIT: Solution is huge amount of data in system clipboard, especially images. Thanks 0BADC0DE for solving it!


Hello.

I have recently notices a big slowdown in start times of plasmashell (KDE Plasma desktop) to around 10 seconds.
As I don't really know where to start here is console output of plasma shell when starting from terminal:

kf.plasma.quick: Applet preload policy set to 1                                                                       ✔ ╱  

Most of the delay happens between line 'Cyclic dependency detected between "file:///usr/share/plasma/plasmoids/org.kde.plasma.notifications/contents/ui/global/Globals.qml" and "file:///usr/share/plasma/plasmoids/org.kde.plasma.notifications/contents/ui/NotificationHeader.qml"' and 'libkcups: 3 "Brother_MFC-J6947DW"'.
So far I have tried disabling cups.path using systemctl and also removing my printer, resetting appearance settings to default, disabling composition but none of them made any difference.
If some more logs are needed please say so and I will provide them.
As a side note, no, disk is not bottleneck (nvme).

Thanks in advice!

Re: [SOLVED] Long plasmashell start times.

Does it start faster when you remove https://archlinux.org/packages/extra/x8 … t-manager/ ?

Re: [SOLVED] Long plasmashell start times.

After removing with `sudo pacman -Rs print-manger` and restarting I couldn't see any difference.

Re: [SOLVED] Long plasmashell start times.

So it's not related to libkcups.
Possibly same as https://bbs.archlinux.org/viewtopic.php?id=281710

Re: [SOLVED] Long plasmashell start times.

It's seems so.... so could it be upstream bug?

Re: [SOLVED] Long plasmashell start times.

Are you on Xorg or Wayland?

I am the other KDEr with a similar problem.
But I am on Wayland.
I think it is more on Qt/KDE/Plasma than Xorg/Wayland. My issue is only with a panel requiring 5 to 10 seconds to show up. Just that, though.

Re: [SOLVED] Long plasmashell start times.

Also I want to note that this delay didn't appeared from nowhere, it seems that over time it was becoming longer and longer so maybe it tries to load some logs?

I had the same impression...
Which display manager are you using?
I am using "aur/sddm-git 0.19.0.170.g3e48649-1" .

Re: [SOLVED] Long plasmashell start times.

Same, as I originally was wayland sddm package just crashed so I installed sddm-git and also forced it using config (/etc/sddm.conf.d/default.conf) to ALWAYS use x11 for it self.

Re: [SOLVED] Long plasmashell start times.

Try to setup your clipboard manager to just 128 items.
If it doesn't fix, try then to clean up the clipboard history.
