3. Use KDE Plasma
4. Lock laptop (Meta+L)
5. Go away from laptop for some time
6. Go back and try to unlock it back
7. Laptop doesn't show anything even on external display

More Info

No response

Start by reviewing nvidia-bug-report.log.gz and nvrm_errors_after_wake.log.gz, collected with nvidia-bug-report.sh and journalctl. Compare the KDE Plasma screen-lock and energy-saving path with the successful Sleep behavior. Done would require reproducing the intermittent black screen and identifying a confirmed open-driver fix; the issue names no source file or test.
