[SOLVED] GDM 3.28 lost gnome on Xwayland and Weston, only Xorg is poss

Hello world

After upgrade to gnome 3.28 the choices in GDM are lost. Before choices  with gnome 3.26 (GDM 3.26) :

- Gnome (Xwayland)
- Gnome on Xorg (Xorg)
- Weston (Wayland)

With gnome 3.28 GDM show :

- Gnome (Xorg)
- Custom (don't work)

Is it possible to configure GDM 3.28 for choices of session be same of GDM 3.26 ?

Thank you for help.

I had a similar problem with 3.26 and solved it by using early KMS (see https://wiki.archlinux.org/index.php/Ke … _KMS_start ). But i dont know if this works for other gpus than intel.

I found this here: https://bbs.archlinux.org/viewtopic.php?id=225690&p=2

I tryed to write Modules=(i915) in /etc/mkinitcpio.conf, but does't work. GDM 3.28 read this path /usr/share/xsessions/ and not this /usr/share/wayland-sessions/

Same problem here, it seems to be a bug introduced in the latest version.

@ gnomeuser: have you updated the initial ramdisk image with "mkinitcpio -p linux"?

Thank you zapphot, yes I do. I updated the initial ramdisk with "mkinitcpio -p linux", but it's the same thing. This bug is here : https://bugs.archlinux.org/task/57957
This problem affect only computers with hybrid GPU, so do you know if your problem with gnome 3.26 concerned all computers ( with one GPU and hybrid GPU) or like here, only hybrid GPU ?
Justly gnome 3.28 with mutter was supposed to better manage hybrid GPU : https://mail.gnome.org/archives/gnome-a … 00013.html

Hello
I solved this problem, gnome-shell 3.28 can't work with Xwayland if the proprietary driver nvidia is installed. It's necesary to install the free driver "nouveau" (new) instead. But this driver did a blackscreen with my laptop. I solved this problem at create this file :
# nano /etc/modprobe.d/nouveau_blacklist.conf
And I writed :
blacklist nouveau
After in tty console, I removed nvidia driver and install the driver "nouveau" : xf86-video-nouveau; I rebooted and all session are proposed by GDM, and it work with Xwayland.

That is not a solution, unless you really do not want to use your graphics card

Yeah, you're right. But that's enough until the bug is fixed.
