Symptom & Impact

System resumes to black screen or frozen session after suspend.

Environment & Reproduction

Ubuntu 24.04 laptops with hybrid graphics or specific GPU drivers.

Root Cause Analysis

GPU driver resume bug, power management incompatibility, or compositor crash on wake.

Quick Triage

Try SysRq REISUB recovery and test resume behavior on Xorg vs Wayland session.

Step-by-Step Diagnosis

Review journalctl -b -1 for previous boot resume errors and check kernel DRM messages for GPU timeouts.

Solution – Primary Fix

Update kernel and graphics drivers via apt, adjust sleep settings, and apply vendor-recommended kernel parameters.

Solution – Alternative Approaches

Disable suspend temporarily and use hibernate or screen lock until patched driver is validated.

Verification & Acceptance Criteria

Ten consecutive suspend/resume cycles complete without black screen or session crash.

Rollback Plan

Remove added kernel parameters and boot previous known-good kernel entry from GRUB.

Prevention & Hardening

Track OEM kernel recommendations and test power-state behavior after every major update.
