Symptom & Impact

Desktop session restarts or freezes due to repeated gnome-shell crashes.

Environment & Reproduction

Usually triggered by incompatible GNOME extensions.

gnome-extensions list
loginctl session-status
sudo journalctl /usr/bin/gnome-shell -n 80

Root Cause Analysis

Extension API mismatch or corrupted extension cache destabilizes shell.

Quick Triage

Disable all extensions and test session stability.

gnome-extensions disable --all
killall -3 gnome-shell
sudo journalctl /usr/bin/gnome-shell -n 120

Step-by-Step Diagnosis

Enable extensions one by one and identify the crashing component.

gnome-extensions list
gnome-extensions info 
sudo journalctl -b -0 | grep -i gnome-shell

Solution – Primary Fix

Remove incompatible extensions and clear local extension cache.

rm -rf ~/.local/share/gnome-shell/extensions/
gnome-extensions disable 
reboot

Solution – Alternative Approaches

Switch to default Ubuntu session profile for stability.

gsettings reset-recursively org.gnome.shell
reboot

Verification & Acceptance Criteria

GNOME session remains stable with no repeated shell crash logs.

loginctl session-status
sudo journalctl /usr/bin/gnome-shell -n 50

Rollback Plan

Reinstall previously removed extension versions if required.

gnome-extensions install 

Prevention & Hardening

Only deploy extensions verified for current GNOME version.

gnome-shell --version
gnome-extensions list
