Symptom & Impact

GNOME session becomes unstable with freezes or logout loops after extension changes.

Environment & Reproduction

Ubuntu 24.04 desktop with GNOME Shell extensions from extensions.gnome.org or local installs.

Root Cause Analysis

Extension API mismatch with current GNOME version or conflicting shell hooks between extensions.

Quick Triage

Switch to a TTY and disable user extensions using gsettings or gnome-extensions command.

Step-by-Step Diagnosis

Inspect user session logs with journalctl –user -b and identify extension stack traces. Test with all extensions disabled.

Solution – Primary Fix

Remove or update incompatible extensions, clear extension cache, and re-enable only validated versions.

Solution – Alternative Approaches

Create a clean user profile to isolate per-user shell settings from system-level issues.

Verification & Acceptance Criteria

GNOME login and desktop remain stable for multiple sessions with no shell crashes.

Rollback Plan

Restore previous extension set from backup and disable auto-updates for problematic extension.

Prevention & Hardening

Keep extension count minimal and verify compatibility after every major desktop update.
