Re: Troubles after update Arch.

MOZ_ENABLE_WAYLAND=0 firefox opened FF immediately! (Cached?)

MOZ_ENABLE_WAYLAND=1 firefox also almost immediately opened FF (but a bit slower).

Re: Troubles after update Arch.

Due to comparison.

I already sent journal slice of now:
I'm sending again latest slice:

VS Code looks a little odd, but works fine.

Re: Troubles after update Arch.

What is that?
It's gonna take a moment for sure and in the older boot runs much later.

When testing firefox, "firefox" by default will only spawn a new window when there's a running instance.
You'll either have to "killall firefox" or run "firefox -no-remote"

Re: Troubles after update Arch.

Thanks so much for hints and for your time.

Obviously something odd happens with my computer. Before after turn on laptop (arch linux) black screen with blinking cursor took not longer than few. Now I can count 20s during nothing happens before black screen with cursor (terminal on startup) even start blinking. I looked in journal before (even years before and there was a lot of errors - usually after updates what asked "manual interventions", but I succeed to manage it somehow.
Wayland is something I used newer before. (Zero experience).
I have no idea how and why when I count during system up, now tool longer time than before even journal shows different.

Can you help me to make decision: Reinstall arch on current laptop or install arch on much stronger desktop computer which is now under Windows).

Device name	DESKTOP-XXXXXX
Processor	AMD Ryzen 9 3900X 12-Core Processor             (3.80 GHz)
Installed RAM	64.0 GB
Device ID	XXXXXXXXXX
Product ID	XXXXXXXXXX
System type	64-bit operating system, x64-based processor
Pen and touch	No pen or touch input is available for this display


Edition	Windows 11 Pro
Version	24H2
Installed on	13/12/2024
OS build	26100.4946
Experience	Windows Feature Experience Pack 1000.26100.197.0

I need a both OS on separate machines. So, I can switch Win on laptop and Arch on desktop but I'm a little confused will be win even be able to work on so old hardware I have on laptop?

For now I will run again system update to check if something new updated in arch packages.

Thanks again for your help. I'm going step by step again trough your hints and links you sent me and will try to figure out what happening exactly, (but slow load is not so big problem for me because I usually using both Win and Arch for coding (not gaming at all). Much important is: apps works fine now as before).

Re: Troubles after update Arch.

I'd suggest to check systemd-analyze to figure what's stalling the boot.
I don't think the problem is your HW being too weak and while uncomposited X11 will typically perform better (require less battery) than any wayland compositor, gnome/wayland should™ outperform gnome/x11

Re: Troubles after update Arch.

It seems you are right.
Something makes startup very slow. (slower than numbers shows).
Today appeared popup after system up:

No big deal, arch still working.

Re: Troubles after update Arch.

Seems to be https://archlinux.org/packages/extra/an … ules-hook/ ?
Also please don't copy and paste out of the pager

systemd-analyze blame --no-pager

and oc

systemd-analyze plot | curl -F 'file=@-' 0x0.st

will give fancy graphics

Huh, it seems nginx must be for this?!

Re: Troubles after update Arch.

No, good god
502 is a server error message from 0x0.st
Try again - if it doesn't work, "systemd-analyze plot > some.svg" and upload that wherever you can.
