after a boot/reboot I can only select GNOME or GNOME classic in GDM, where the GNOME session is on Xorg apparently. After logout/login I can select GNOME, GNOME classic and GNOME on Xorg, where GNOME is on wayland. Any idea why this choice is not being offered after boot/reboot?
But on Arch wiki I found this. So I added i915 to the MODULES section in mkinitcpio.conf. After regenerating initramfs and reboot the three options (‘GNOME’, ‘GNOME classic’ and ‘GNOME on Xorg’) are there in GDM, and GNOME session is on wayland May switchting to early KMS start have any side effects?
