Steps to reproduce

1) Install openSUSE Tumbleweed to Virtualbox 7 machine windows host (windows
10)
2) Install LXQT pattern and switch to it as default desktop
3) Remove openSUSE preinstalled virtualbox guest tools and kmp
4) zypper in dkms (vbox guest needs it)
5) Install Virtualbox additions via Devices/Insert Guest Additions CD Image and
running apporiate tool as root (sudo)
6) Reboot

Expected result: System running normally with added benefits (fullscreen
resolution etc)

What happens: lxqt desktop loads several times and finally gives up saying it
has crashed several times and won't restart until next login.

I notice 5 lines on journalctl with lxqt filter
