Latte crashing after switch to wayland

Hey there,
trying to fix the Wayland boot issue, @dejv78 and I have decided to reinstall our systems.
After that finished for me, I was finally able to boot into wayland, but now there is a new problem: Latte dock won't start.
It always spits out this error: interface 'kde_output_device_v2' has no event 14
Note: I am using the kde git packages.
Why is that?

I couldn't find any of that :confused:
Anyways, it's "not a bug": 441718 – Latte dock crashes instantly on wayland sessions.

So, this is after a fresh install and a full update?

No extra software from the AUR installed?

Just a virginal freshly updated install?

I just installed this (And updated), yes.
I installed some of the software which is important to me, so no no-AUR-installation.

Latte works on x11 lol

Have you tested Latte with all widgets disabled. Widgets are one of the most common reasons for latte crashes.

Latte crashes even with latte-dock --default-layout

Have you thought about trying a KDE barebones install? A bit more effort, but you seem like a very competent user.

Yikes. I am a fan of the garuda configs and I just went the extra mile to reinstall garuda just to get wayland to work... I am not a fan.

It was just a thought to see if we could pin down where the issue originates. I fully understand your hesitancy to go that route.

It may simply be another case of KDE Wayland not quite being ready for prime time yet.


Did you start on zero?

With one monitor?

Latte crash maybe from your 3 monitor configuration?

I sure hope this is the problem.
Reinstalling from time to time isn't too bad though. Keeps the system clean and instandly de-bloats :wink:

(Unless you reinstall all the old packages you had installed, as I did xD)

Huh? I only have two screens

I think Screen-1 is all of the screens added together or something like that.

Like what the other person saw when one shared their screen with discord about a year ago


You have two monitors in one screen, ok.

Again, do you try with one monitor in one screen with same size/dimension?

I think so too, with my one monitor :smiley:


Okay I have tried this with only one monitor, which didn't work, but I have something else that I completely forgot about:
Latte "works" for a short while (It just shows the config gui and warns about an error in the garuda config - An orphaned subcontainment or something like that - And when trying to switch configs, latte crashes and only returns the above error

EDIT: Oh the LOGS! 0bin - encrypted pastebin

Did somebody say it was? Hmm, I guess this guy did. :slight_smile:

My experience with Wayland has been horrible, it crashes and is very buggy. KDE refused to work right when I used Wayland. IMHO Wayland is not ready for prime time.

What is the crash report?


There is no crash report. I had journalctl -xf open and even checked coredumpctl

Close latte, add a default plasma panel, start latte

If it crashes, KCrash will give you a report
