We have no way to sanely add safe modes if there are no modes we can compare with, thus don't try. Fixes the following crash: #0 are_all_modes_equally_sized at ../src/backends/native/meta-output-kms.c:284 #1 maybe_add_fallback_modes at ../src/backends/native/meta-output-kms.c:310 #2 init_output_modes at ../src/backends/native/meta-output-kms.c:347 #3 meta_output_kms_new at ../src/backends/native/meta-output-kms.c:414 #4 init_outputs at ../src/backends/native/meta-gpu-kms.c:332 #5 meta_gpu_kms_read_current at ../src/backends/native/meta-gpu-kms.c:368 #6 meta_gpu_kms_new at ../src/backends/native/meta-gpu-kms.c:403 #7 create_gpu_from_udev_device at ../src/backends/native/meta-backend-native.c:461 #8 init_gpus at ../src/backends/native/meta-backend-native.c:551 #9 meta_backend_native_initable_init at ../src/backends/native/meta-backend-native.c:632 Fixes: 877cc3eb7d44e2886395151f763ec09bea350444 Related: https://bugzilla.redhat.com/show_bug.cgi?id=2127801 Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2646> |

Mutter
Mutter is a Wayland display server and X11 window manager and compositor library.
When used as a Wayland display server, it runs on top of KMS and libinput. It implements the compositor side of the Wayland core protocol as well as various protocol extensions. It also has functionality related to running X11 applications using Xwayland.
When used on top of Xorg it acts as a X11 window manager and compositing manager.
It contains functionality related to, among other things, window management, window compositing, focus tracking, workspace management, keybindings and monitor configuration.
Internally it uses a fork of Cogl, a hardware acceleration abstraction library used to simplify usage of OpenGL pipelines, as well as a fork of Clutter, a scene graph and user interface toolkit.
Mutter is used by, for example, GNOME Shell, the GNOME core user interface, and by Gala, elementary OS's window manager. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.

Git messages
Commit messages should follow the GNOME commit message
guidelines. We require an URL
to either an issue or a merge request in each commit. Try to always prefix
commit subjects with a relevant topic, such as compositor: or
clutter/actor:, and it's always better to write too much in the commit
message body than too little.
Default branch
The default development branch is main. If you still have a local
checkout under the old name, use:
git checkout master
git branch -m master main
git fetch
git branch --unset-upstream
git branch -u origin/main
git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/main
