Gnome won't start after updating to Gnome 50

Notebook with Xeon W-10855M, GPU1: Intel UHD Graphics P630, GPU2: Nvidia Quadro T1000, Arch Linux: Linux 6.19.11-arch1-1

This is the log I get after booting.

From the hardware description it looks like the system uses hybrid graphics (Intel UHD P630 + NVIDIA Quadro T1000). After major GNOME updates this kind of setup can sometimes break if the graphics stack is not fully aligned.

The framebuffer errors in the log usually indicate that Mutter cannot initialize the rendering backend correctly. In many Arch systems this happens when the Mesa stack, kernel modules, or NVIDIA driver are out of sync after an update.

Some things worth checking:

1. Make sure both Mesa and the NVIDIA drivers are fully updated:

sudo pacman -Syu

sudo pacman -S mesa nvidia nvidia-utils

2. Verify that the correct GPU modules are loaded: lsmod grep -E “nvidia i915

3. If there are any custom Xorg configuration files (for example under /etc/X11/xorg.conf.d/), try temporarily removing them since they can interfere with GNOME’s automatic GPU selection.

4. Test whether GNOME can start manually from a TTY: dbus-run-session gnome-shell --wayland

Hybrid GPU systems sometimes retain older configuration files from previous setups, and removing those or reinstalling the graphics stack often resolves issues after a GNOME upgrade.
