Comment 1 Steve Allen 2022-10-12 05:43:07 UTC
I should note that it doesn't matter whether loginnis with x11 or wayland
Comment 2 Vlad Zahorodnii 2022-10-12 06:47:54 UTC
Do you use any scripts? Can you post the output of `qdbus org.kde.KWin /KWin supportInformation`?
Comment 3 Steve Allen 2022-10-12 07:04:50 UTC
Not a script, but I did use kwin-bismuth, but uninstalled that to rule it out. I wonder if the windows are trying to tile / kwin is trying to use bismuth decoration even though bismuth is not installed anymore?

The first window I open flashes up very quickly (in a tiny square) then disappears.

If I login to tty3 I get `error org.freedesktop.Dbus.Error.UnknownMethod`
`No such method 'supportinformation' in any interface at object path 'KWin' (signature '')`

I need to set up ssh access to the machine to help with cut/pasting commands and errors.

There is more stuff I've tried here:

Comment 4 Vlad Zahorodnii 2022-10-12 07:48:57 UTC
Can you attach kwin logs after step 3 too? Use `journalctl --user-unit plasma-kwin_x11` or `journalctl --user-unit plasma-kwin_wayland` to get kwin's logs
Comment 5 Steve Allen 2022-10-12 07:58:18 UTC
I will struggle to cut/pates logs. I only have my phone and the laptop (which I can only use the tty on) with me

I won't be able to ssh in from my desktop until friday.

Is there anything I should be looking for in the logs?
Comment 6 Steve Allen 2022-10-12 08:02:56 UTC
Actually output is `--no entries--`

Is there a way to backup and clear my Kwin settings (e.g decoration etc) back to default?
Comment 7 Steve Allen 2022-10-12 08:08:24 UTC
If I create a new user, login with that user (to see if its my user setting causing issues) cycles the ssdm loginscreen

Yes, copy or move ~/.config/kwinrc somewhere

That's really helpful, thanks.

Moving the config worked a treat. Seems its regenerated and windows are
appearing as normal.

Will miss Bismuth tiling, hopefully the depends issue with the 20.04 base
will get sorted next release, or the bismuth dev will find a fix

Thanks for your help, is there anything I can provide (from my old kwinrc)
that may be helpful?
