Reproducable gnome-shell crash when display powers off.
I'm wondering where the best place to report this is?
I think any SEGFAULT should be taken seriously as it's potentially exploitable, so I'd like to report this bug to the proper party so it can be fixed upstream, but I'm not sure the right place to do so because I don't know the root cause. Could this be something that the kernel contributors could address, or must it be patched by Nvidia?
I really hope its the former because I don't have high hopes that Nvidia will fix this. That's what I get for not buying a card with first-party open source kernel drivers.
My system uses the nvidia_drm and nvidia_modeset modules controlling an MSI GeForce RTX 3060 connected to a Samsung LU32H750UMNXZA.
The dmesg output from around the time I reproduced the crash is included below.

Re: Reproducable gnome-shell crash when display powers off.
Get rid of the simple-drm device by properly enabling modesetting first and foremost: https://wiki.archlinux.org/title/NVIDIA … de_setting
If that doesn't fix it, test behavior on a normal non hardened kernel. These often contain patches that can trip things up especially in the DRM space.

Re: Reproducable gnome-shell crash when display powers off.
Gnome 45?
Possibly https://gitlab.gnome.org/GNOME/mutter/-/issues/3037
Try to export "MUTTER_DEBUG_KMS_THREAD_TYPE=user", https://wiki.archlinux.org/title/Environment_Variables
(The simple-framebuffer warnings are a couple of seconds away from the gnome segfault, check the journal instead of dmesg for more userspace context and possibly a backtrace)

I found that the crash does not occur if I set the nvidia_drm.modeset=1 kernel parameter and use the vanilla linux and nvidia packages (I was using nvidia-dkms before with my linux-hardened kernel).

I'm running GNOME 44, but the symptoms of the bug you linked to the same as what I'm experiencing.
After I added export MUTTER_DEBUG_KMS_THREAD_TYPE=user to my .profile I got a stack trace from gnome-shell when it dumped core.
Oct 11 17:30:03 hesiod systemd-coredump[2578]: Process 1728 (gnome-shell) of user 1000 dumped core.

ELF object binary architecture: AMD x86-64It looks like every single thread was calling into libc.so when the segfault occurred. Shortly before the crash gnome-shell reported an X Window System error.
Oct 11 17:30:01 hesiod gnome-shell[1728]: Received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
(Details: serial 6999 error_code 8 request_code 140 (unknown) minor_code 7)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the MUTTER_SYNC environment
variable to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the meta_x_error() function.)Both of the above log events occurred using the vanilla kernel and nvidia packages, but without the nvidia_drm.modeset=1 kernel parameter set.
Although I have a solution for my problem, it still seems like this should be reported upstream.
Also, I need to correct my disparagement of Nvidia. They do in fact release open source linux drivers, which are used to build the linux-open package. Good on them, though AMD has been doing this for much longer.

Re: Reproducable gnome-shell crash when display powers off.
MUTTER_DEBUG_KMS_THREAD_TYPE=user is not required to see any backtraces and isn't relevant for Gnome 44 either.
The backtraces show aborts for an xrandr error and along your other findings, this is because of the simpledrm device.
(It's likewise also not because of nvidia; setting "nvidia_drm.modeset=1" will just signal the kernel to not create a simpledrm device, regardless of the HW even)
Do you still get crashes w/ nvidia_drm.modeset=1 and the hardened kernel?
gtk has committed suicide for X11 errors ever since 
and the issues around the simpledrm device are otr, see eg. https://bugs.archlinux.org/task/73720 and https://bugs.archlinux.org/task/79528
Status quo is that it's enabled and we tell everyone how to disable it
Fedora has meanwhile dropped the https://fedoraproject.org/wiki/Changes/ … verRemoval (for now)

Yes. It also crashes when I have the hardened kernel installed with nvidia instead of nvidia-dkms.

I don't think I understand the interaction of the components here. My understanding is that simpledrm (or simple-framebuffer?) is a device in the kernel's device tree, whereas the legacy drivers referred to in fedora project wiki page are Xorg display drivers which live in user-space. Is the issue that when the simpledrm is being used, one of these legacy display drivers is also used, and these are incompatible?
In any case, I'm considering switching to Wayland because it's the future and sticking with X11 seems to be contributing to issues.

Re: Reproducable gnome-shell crash when display powers off.
The idea was to use the hardened kernel (along nvidia-dkms) and modeset enabled (to get rid of simpledrm) to see whether the hardened kernel still works.
w/o nvidia-dkms you won't have a kernel module for the hardenend kernel, nvidia-util blocks nouveau and you run into completely different issues.
simpledrm provides a generic, kms capable pseudo-device and kernel module that allows the use of the modesetting driver (or wayland) whereas the vesa and fbdev X11 drivers don't require KMS (unlike every other X11 driver or wayland)
I'm considering switching to Wayland because it's the future and sticking with X11 seems to be contributing to issues
You can use whatever display server you want, but if we want to point at issue contributers:
The one you faced is pretty much exclusively "caused" by wayland (or the desire to have a fallback system for it as would exist for X11 w/ vesa and fbdev drivers)
