this looks good, its look like normal plasma logs, except those mce errors… so on live usb everything looks good…

Yea, normal. So all my log errors have been accumulated over time via software changes, updates, me tinkering blindly etc

yes it looks like it…

What about all this stuff? Should i put it back to how it was?

yes, i have it disabled, even though i had no issue with it, its just another unnecessary service, so just disable it…
did you check logs in the new installation, if everything is ok?

Im not doing a new installation. I dont have the time or energy. I hardly ever actually do a reboot/shutdown so meh. When im feeling a bit better i might get to it, but not ATM.

However, thank you for time and support :+1:

Your NAS is the culprit. The timeout for mounting/unmounting should be decreased (or rather a systemd automount should be used rather than in fstab).

Ok, so how do i decrees the timeout for that?

Regarding the mount at boot, i have already been through all of this without remedy yet System will not mount NAS at boot, although the mount does work fine after its finished booting

I’m reading this kwin_x11 and QDBusConnection hanging on shutdown/reboot / Newbie Corner / Arch Linux Forums and this Kwin_x11 not stopping during shutdown

Looks very similar

Tell me it’s not an arch/Manjaro bug.

Ok so we found that this is a known bug and according to some has been fixed but what does that mean to Manjaro? When does that get pushed to myself?

p.s. I did try not mounting all my NAS but that did not work.

i had same problem.
i did two things.

  1. change your kernel in settings (better to previous versions and of course LTS ones.)

  2. instal all graphic driver (especially ones who has linux name)

Sorry about the late response. This computer is at work and I didn’t have access to it until today. I’m not quite following your instructions. Could you elaborate in detail where to enter what?
Here’s my grub info:
GRUB_DEFAULT=“Advanced options for Manjaro Linux>Manjaro Linux”
GRUB_TIMEOUT=4
GRUB_TIMEOUT_STYLE=no
GRUB_DISTRIBUTOR=“Manjaro”
GRUB_CMDLINE_LINUX_DEFAULT="quiet cryptdevice=UUID=e077faba-536a-4f55-8298…

@fhins please open a new topic with all needed and related info.
It is unclear what your personal problem has todo with this topic besides the title…
Slipping in your own problem in a topic with a similar but not same problem is called thread-hijacking…

The grub config you show is already missing info…
