I've been having this issue for the longest time now, but it just seems as though it's getting worse. Every so often right in the middle of a session, my screen goes black with some sort of error output that displays only for a fraction of a second before disappearing and taking me back to the log-in screen. I'm pretty sure there must be a log report that can flesh out the specifics in terms of what causes these crashes, so I was hoping you guys could point me in the right direction so I can post the results here. I did look in /var/logs/ and I tried opening various logs such as "faillog" but they won't open and I don't know which one has the relevant information. It's worth noting that usually the crashes occur when I'm in my browser (Chrome) or when I have multiple applications open.
Any help would be appreciated. Thanks.
