(this is an inxi from the live usb so the kernel and plasma version are not the same as my install, I tried to get an inxi from the chroot but it came back all garbled)

Garuda (2.6.17-1):
System install date:     2024-03-13
Last full system update: 2024-03-13 ↻
Is partially upgraded:   No
Relevant software:       snapper NetworkManager dracut
Windows dual boot:       <superuser required>
Failed units:            snapper-cleanup.service

after updating plasma my system no longer boots. It seems to start the kernel and everything fine (as I see the boot up messages) but then the screen goes blank (it usually does with it gets to loading sddm) and just stays there. I can’t switch to a diffrent tty or do anything. at this point I use the REISUB keys to reboot my system.

I to see if I could boot a snapshot but the snapshot menu seems to now be missing under grub.

I tried also chrooting from a live usb but when I went to inspect the systemd jorunal I got this

root@garuda-dr460nized-gaming /# journalctl
No journal files were found.

one intresting thing I noticed is if I disable the sddm systemd unit like this
systemctl disable sddm.service
I can succsesfully boot into a tty after rebooting. manually starting sddm with systemctl enable sddm.service gets me into the same broken blank screen as before so it seems its a problem with sddm

I tried the restore snapshot in the live usb but it refuses to restore my snapshot saying it “failed to make a backup of target subvolume”

Thank you for that, it is THE way to go when you get stuck, as long as the command works.

Which SDDM Theme you had in there before the reboot that caused you blank page?

I believe I had Dr460nized (not sugar candy) Thats what I have right now

I got the snapshot menu back by running the garuda boot repair (just a thought I had lol) and was then able to boot into the snapshot before the update.

Strangely I tried updating again, and it worked this time… Something must of gone wrong on the first update (I was building/ installing gamescope from git to test some issues I was having and that was done after the snapshot I restored to, but that shouldn’t cause problems with sddm…)

4

So apparently it was gamescope breaking sddm (no idea how) broke my system again trying to install it. Even worse something seems to have happened to my home partition as it is now read only. So while 8 can boot to a previously working snapshot plasma doesn’t work because it complains that my home directory is read only

5

I’m going to interject here and say the kernel update could have waited. I noticed it during the Plasma updates. IMO kernel updates which Garuda does control should never be done with something like full Plasma system updates.

7

Garuda Linux does not package, maintain, or otherwise control any kernels. The suggestion that Garuda can hold back a user’s kernel update is incorrect.

Even if it were possible, my guess is the team would be unanimously opposed to holding back kernel updates because this is not Manjaro.

Fixed my read only hoome partition by booting an even older snapshot . I restored that snapshot, rebooted and then updated and now everything is fine … as long as I don’t touch gamescope. Uninstalling my currently installed gamescope package(along with any packages that require gamescope in my case arch-gaming-meta gamescope-session-git gamescope-session-steam-git) brings me back to the broken sddm from the OP. Same if I try to install arch’s gamescope or manually build and install my own.

Somehow gamescope-git is intrinsically tied to sddm and removing it or replacing it breaks it.

this reminds me of Gamescope-git blocking KDE Plasma 6 install, afterwards cannot be installed again and Gamescope-git conflicting files, but not sure if that can explain sddm breaking…

here is my gamescope package

It’s Garuda’s OS and you guys do know what’s coming down the pike and do have the ability to block updates til others are done. I stand by what I said that a kernel update should never be done with a desktop update.

10

Technically we can put them on the ignore list, but honestly controlling kernel updates seems a bit too invasive to me (unless its a kernel version known to ABSOUTELY break systems, which is not the case here). Is there any proof that this actually made a difference here?

Honestly this sound more like some old superstitious belief like “don’t open an umbrella inside” than any kind of practical system administration advice.

For the benefit of those following along in this thread, I will double down as well: holding back random packages just because your system needs to have a lot of updates at once is a bad idea which is more likely to break things and introduce complex obstacles for troubleshooting than just taking the update.

As already stated, you should be reviewing your own packages before updating. If you want to hold back this package or that one because you have a strange update routine then knock yourself out, but please don’t advise other people to do the same.

I don’t think there is a clean way to do this, because:

  • Not all users are running the same kernel. There must be like twenty different kernels our users can choose from, with all the custom ones available in the Chaotic repo and such. Not to mention folks who add their own repos for even more options.
  • Not all users are running KDE. So we would have to either:
    • Hold back twenty kernels or whatever for all users, even the ones that aren’t even updating these packages, or
    • Figure out some way to apply the package hold to only KDE users so everyone else can update normally, and then have a userbase which is all techically “up to date” but are all running completely different kernel versions with different modules and driver stacks, etc.

I think Manjaro is able to do it because they keep their repo on the top in pacman.conf and have a lot more packages in it, like the kernels and such. The Garuda repo doesn’t have any kernels in it, nor any of the KDE packages and so on so we would have to come up with something hacky.

If something were super broken upstream and there were no other choice but to intervene to spare everyone from winding up with a busted system, fine: maybe we should consider the intervention. But holding back the kernel updates because some user anecdotally thinks it will be better to not update this group of packages with that one is insane.

Plasma or gamescope, maybe change the topic title.

Nowhere in my post did I advice anyone to do anything. That’s taking my post out of context. I said I don’t believe a kernel update should be done along with major system updates.
