nezzie After rebooting with everything set to Breeze then no "SNI" error and Octopi icon shows.

Reboot doesn't fix to me.

I have not changed anything, I only opened Octopi and Octopi-Notify and look in Journalctl after a fresh installation (first boot) and I still had the problem of notification

As always, and I will spell it out again, most basic info needed is from Octopi > SysInfo
In this case, make sure to note what settings you have changed from default KaOS (ie, Wayland, session, Midna theme, Kvantum widget style).
But much better would be to open a bug report, since this thread now gets all kinds of extra reports, where it is not clear who has what issue.
https://kaosx.us/docs/bugs/
And has any of you checked upstream bug reports for the breeze theme? Since most of what is mentioned here is not an issue at all on Midna.

Well Demm,
I'm happy as I do not have a problem. I only installed to test bvbfan's problem. Fixed as in my earlier post.

    nezzie I only installed to test bvbfan's problem. Fixed as in my earlier post.

    I don't see how "fixed" is to reboot.

    This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

    There is problem with platform plugin - breeze, no Kvantum (which is Midna theme)

    As is clear now, there are separate issues, so please stop dumping them in a forum post, open a bug report for each of the issues you have found. I will no longer respond in this thread.

    No separate issues, the issue only one, it cannot create platform plugin, which result in missing SNI interface.
