[SOLVED] kdeconnect and other apps crashing after switching to wayland

Today I decided to switch from x11 to wayland for my plasma session. After some graphics issues with nvidia PRIME, it seemed like the desktop started, but some apps still seem to crash.

One of these is kdeconnect, with the following trace.

I tried to launch it in shell with debugging enabled with the following env

This gave me the following output

Re: [SOLVED] kdeconnect and other apps crashing after switching to wayland

For quick mitigation try

QT_QPA_PLATFORM=xcb kdeconnect

After some graphics issues with nvidia PRIME

qdbus6 org.kde.KWin /KWin supportInformation

Also probably 

printenv; eglinfo -B; glxinfo -B

Is kdeconnect from the repos or some flatschpak?
You've not partially updated the system? (Notably qt6-wayland is in sync w/ the rest of qt6?)

Edit, possibly relevant: https://bbs.archlinux.org/viewtopic.php?id=314888

Is kdeconnect from the repos or some flatschpak?
You've not partially updated the system? (Notably qt6-wayland is in sync w/ the rest of qt6?)

Edit, possibly relevant: https://bbs.archlinux.org/viewtopic.php?id=314888

I have everything (so also kdeconnect) installed from the repos and have done a full system upgrade before posting, so qt6-wayland is in sync with the other qt6 packages. I have also upgraded my nvidia drivers to 615.71.09-1 and everything still works.

Re: [SOLVED] kdeconnect and other apps crashing after switching to wayland

XDG_SESSION_TYPE=wayland but the rest there says that this is an X11 session, test xeyes, https://wiki.archlinux.org/title/Waylan … plications
How exactly are you starting that session?

Re: [SOLVED] kdeconnect and other apps crashing after switching to wayland

Okay I think I solved it. My laptop is quite old and I used to start my plasma session via .xinitrc, so I still had the following there.

export DESKTOP_SESSION=plasma
exec startplasma-x11

This was run when I started my plasma session via sddm, so it started the x11 session. After removing these lines the wayland session would not start, but I have now switched to Plasma Login Manager and everything seems to work now.
