Pulseaudio or bluetoothd crashing would not log you out. At most only audio would stop working, but usually it will automatically restart and you not notice anything at all.
Pulseaudio or bluetoothd crashing would leave files in /var/crash. So that's further evidence that they are not crashing in this case. So I think you may be looking in the wrong place. I certainly don't see any evidence of pulseaudio or bluetooth crashing in the above log. The session always trying to enable bluetooth and failing when it can't is not an error, it's just an informational log message. Try looking for other parts of the system failing, which would better explain all the symptoms you see. ** Summary changed: - [regression] pulseaudio+bluetooth crash causing user to be logged out (since pulseaudio 1:8.0-0ubuntu3.9) + Users randomly getting logged out of their machines -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1767065 Title: Users randomly getting logged out of their machines To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1767065/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
