[SOLVED] GDM failing to start with Wayland since update to 43

This morning complete Gnome stack was updated to 43 on my system. After the update GDM fails to start. I only get a black screen and can't even switch to one of the other terminals (I need to force shutdown with the power button and edit boot line to enter multi user target.
When I force the usage of X11 the GDM starts as expected.
I would like to avoid using X11, since everything works much smoother under Wayland for me.
I have a laptop with Nvidia Optimus, but I've disabled Nvidia card with udev rules (I've checked and lspci doesn't report that the Nvidia card exists).

Here's the output of 'journalctl -u gdm' for the last two failed startups:

Is anyone else experiencing similar issues or has any suggestions?

Thanks for the info VoDo. At least I'm not the only one with the issue...

same here, also happened previously when trying FCGU repository. I was using mutter-x11-scaling. disabling wayland is a workaround.

That also allowed me to start gnome. Thanks, but how did you know this was the current issue?

Same here; removing gstreamer-vaapi is a workaround to get wayland working.

Another workaround that I found here is to comment this line in

/etc/pam.d/system-auth
#-account   [success=1 default=ignore]  pam_systemd_home.so

Afterwards I can launch the gnome-session on Wayland without removing gstreamer-vaapi.

Re: [SOLVED] GDM failing to start with Wayland since update to 43

electrickite in the bug report posted above found a better solution to this issue (at least for users using Intell); installing intel-media-driver package. With this package installed there's no need for uninstalling gstreamer-vaapi.
I'm marking this as solved, since this solves the issue completely for me, without the need for removing pacakges.
