After updating to gnome-3.28 my laptop runing nouveau driver with a NVIDIA Corporation GK208M [GeForce 920M] (rev a1) and starting gnome-session on Xorg (but also on wayland) I get a gnome-shell coredump like this:

Additional info:

* package version(s)

gnome-shell 3.28.0-1
mutter 3.28.0-1
gnome-session 3.28.0-1
gnome-shell-extensions 3.28.0+1+g496ae16-1

* config and/or log files etc.

I start a fresh session environment with only the extensions provided by the gnome-shell-extesions package.

Steps to reproduce:

In my case trying to open some extensions preferences makes gnome-shell crash or starting some x11 apps (like XPaint) also make gnome-shell core dump.
This task depends upon

Not sure if this related, but today after upgrading to 3.28 gnome shell won't start. Attaching core dump info. Same thing happens with both, xorg and wayland.


gnome-shell 3.28.0-1
mutter 3.28.0-1
gnome-session 3.28.0-1
gnome-shell-extensions 3.28.0+1+g496ae16-1

As noted by Mantas, since my update this morning, gnome-shell won't start. Just after entering my password, the following message is displayed in the logs:

Mar 26 10:17:34 archlinux gnome-shell[1854]: libnm symbols detected; Mixing libnm with libnm-util/libnm-glib is not supported

Mantas, Phil, your problems are unrelated to this bug.

I believe this happens only on laptops with discrete nvidia GPU and blob driver.
In my case (intel+nvidia):
If nvidia GPU is preemptively turned off via acpi_call the system is frozen (no X, no alternate console).
If it is turned on X session works as of gnome-session 3.28. To start wayland session I can stop gdm (including whatever sessions are started), rmmod nvidia_drm nvidia_modeset nvidia, start gdm.
If I blacklist nvidia nvidia_drm nvidia_modeset, but don't turn off nvidia GPU, wayland starts automatically.

Guess that's upstream bug, caused by recent support for hybrid GPU laptops. The strange thing is why it doesn't work with nouveau. Jonas Ã…dahl said he was testing i915+nouveau setup.

Since the last bunch of gnome-related pkgs update (3.28.1) it seems it's working again. No more crashes.
I still don't use wayland and use nouveau instead of nvidia propietary driver.

So, at least for me, the bug is solved, don't know how but it's solved :)
