I can see your system choosing to use X very early...
It looks like you have a partially broken system (from upgrades/nvidia-
installer/hacking/something else):
okt 20 13:13:21 mavi-vaadin gpu-manager[1130]: /etc/modprobe.d is not a file
okt 20 13:13:21 mavi-vaadin gpu-manager[1130]: /etc/modprobe.d is not a file
okt 20 13:13:21 mavi-vaadin gpu-manager[1130]: /etc/modprobe.d is not a file
okt 20 13:13:21 mavi-vaadin gpu-manager[1130]: /etc/modprobe.d is not a file
okt 20 13:13:21 mavi-vaadin gpu-manager[1130]: Error: can't open
/lib/modules/4.13.0-16-generic/updates/dkms
okt 20 13:13:21 mavi-vaadin gpu-manager[1130]: update-alternatives: error: no
alternatives for x86_64-linux-gnu_gfxcore_conf
So you can try rebuilding that with:
sudo apt install --reinstall kmod dkms
Later in the log, your problem becomes more apparent:
okt 20 13:13:28 mavi-vaadin gnome-shell[1666]: Can't initialize KMS
backend: could not find drm kms device
That will definitely mean Wayland is not an option. Try the above fix.
And if that doesn't work then please log a bug on bugzilla.gnome.org
mentioning that:
okt 20 13:13:28 mavi-vaadin gnome-shell[1666]: Can't initialize KMS
backend: could not find drm kms device
when you have both:
