Now this is something really weird. I said for the hell of it to try and see if this would fix the issue. I was thinking that to save energy maybe the system tried to power down wifi/bluetooth and such during idle times.
I added intel_idle.max_cstate=1 to the kernel start options in the grub config. The main person I'm testing with hasn't reported any forced logouts since this change. Based on this solution: https://askubuntu.com/questions/761706/ubuntu-15-10-and-16-04-keep- freezing-randomly Is the CPU/ ACPI calls going into a lower state causing problems with the login/logout state of the machine? This might not have anything to do with pulse, but it opens an entire new can of worms. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1767065 Title: [regression] pulseaudio+bluetooth crash causing user to be logged out (since pulseaudio 1:8.0-0ubuntu3.9) Status in pulseaudio package in Ubuntu: Incomplete Bug description: Hello, I'm a sysadmin and have gotten multiple reports recently from users of them randomly getting logged out of their machines. From what I can tell from the journalctl printout this appears immediately after either bluetoothd or pulsaudio crashes. This is happening multiple time each day for each user. It doesn't happen to all users, but the reports seem to be getting more frequent by the day. From what I have noticed there recently was an update for pulseaudio and its bluetooth integration.
