Post #71 Continued... Apport Backtrace: - Temporarily forced using: sudo service apport start force_start=1 - Simulated the condition for crash/logout - Logged back but no notification from update-notifier - Checked /var/crash/executable_path.uid.crash but no report found there Looks like apport fails to report the crash. Could it be a GPU lockup? https://wiki.ubuntu.com/X/Troubleshooting/Freeze
Workaround: I reported a workaround that worked with my laptop. Since then I have consistently verified the workaround. If the laptop is powered on AC main there are no crash/logouts. Auto logouts only when using battery power. Could power management linked to GPU lockup. Wild guess: Some kind of wait/timeout issue?
