The only note-worthy log entries I see in that folder are in x-0-greeter.log, and I'm not 100% sure they're related to this bug, I've attached the log file.
I have just managed to reproduce this again: 1) I sshed into my machine from another machine to verify when my machine crashes 2) On my machine I hit ctrl+alt+L to start the lock screen 3) Waited a few minutes (not sure how long I actually need to wait) 4) pressed the num lock key At that point, the LED lights on my keyboard and mouse turned off, and the monitors displayed the "not connected" message. On the machine that I used to ssh with, the terminal had frozen. The reason I assigned this to lightdm is because I've reproduced this bug on the greeter screen where (I think) it's the only thing running, and it crashes the greeter leaving just the background image/colour displaying. ** Attachment added: "x-0-greeter.log" https://bugs.launchpad.net/ubuntu-gnome/+bug/1543782/+attachment/4648181/+files/x-0-greeter.log -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-screensaver in Ubuntu. https://bugs.launchpad.net/bugs/1543782 Title: Complete system freeze some time after lock screen starts Status in Light Display Manager: Incomplete Status in Ubuntu GNOME: New Status in gnome-screensaver package in Ubuntu: Invalid Bug description: Ever since updating to 15.10 my computer has been freezing every day. Usually this happens after I've left work, and since I leave my computer on, I manually start the screensaver (ctrl+alt+L), and when I come back the next morning, the computer is completely unresponsive, even to sysrq. Gnome screensaver itself doesn't appear to be the culprit since I can turn it on, then log back into my system any time within perhaps 5 minutes. Looking at my root journalctrl output, yesterday, it appears to have crashed 30 minutes after I logged out (I was zeroing a drive with dd, and was issuing a kill -USR1 to track the progress every 30 seconds). At first I thought it might be a botched upgrade from 15.04, so I tried a clean reinstall last week, but it still freezes. There is also nothing in the logs that would indicate an error/crash. The only potentially related piece of information is that I use gnome- shell, installed via ubuntu-gnome-desktop. I'm not sure what package to file this under since I don't know how to reproduce, or how to diagnose the issue. Any debugging advice will be appreciated since this issue is really starting to annoy me.
