Comment # 31 on bug 1090122 from Vladimir FROMENT

After a lot of tests, I installed from scratch beta 234.2. I noticed an option
at GDM login screen which proposed to load Gnome over Wayland OR�load Gnome
over Xorg.
I don't know if this option was present in the previous betas, but it does the
trick. Gnome loads without the Intel GUC driver
(/sys/module/i915/parameters/enable_guc is set to 0, with default bootloader
parameters).

I still have some instabilities in one use case on Xorg I�will report in detail
when I�have more time in a few days (external screen detected on Xorg, but
after reboot, GDM do not show up anymore). But regarding the initial report, I
would say the issue is solved or workarounded ;)
