Symptom & Impact

After suspend, display remains black and session appears hung.

Environment & Reproduction

Common on laptops with specific GPU/driver combinations.

systemctl suspend
loginctl session-status
sudo journalctl -b -1 | tail -n 120

Root Cause Analysis

Resume path fails in graphics stack, compositor, or power management layer.

Quick Triage

Collect prior boot logs and test alternate power settings.

sudo journalctl -b -1 -k | grep -Ei 'drm|gpu|amdgpu|i915|nvidia'
cat /sys/power/mem_sleep

Step-by-Step Diagnosis

Analyze suspend/resume events and GPU-related kernel errors.

sudo journalctl -b -1 | grep -Ei 'suspend|resume|gnome-shell|gdm'
sudo dmesg | grep -Ei 'drm|gpu'
loginctl show-session $XDG_SESSION_ID

Solution – Primary Fix

Switch sleep mode and update graphics stack packages.

echo s2idle | sudo tee /sys/power/mem_sleep
sudo apt update
sudo apt full-upgrade -y
sudo systemctl restart gdm

Solution – Alternative Approaches

Temporarily disable suspend and use hibernate/poweroff workflows.

sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target

Verification & Acceptance Criteria

System resumes with functional display and input.

systemctl suspend
loginctl session-status

Rollback Plan

Revert power target masks and mem_sleep settings.

sudo systemctl unmask sleep.target suspend.target hibernate.target hybrid-sleep.target

Prevention & Hardening

Keep firmware and kernel updates current on affected hardware models.

uname -r
sudo fwupdmgr get-updates
