I'm running Gnome on Ubuntu 17.04. I had gnome-terminal in fullscreen, neovim in a tmux session, a background process compiling code, and Chromium running as well, when my system froze up on me. I could move the mouse cursor, barely, with extreme lag, but that's all I could do. I waited several minutes, then tried Ctrl-C, Ctrl-Alt-Delete, Alt-F2, but nothing responded.
Finally, I gave up and held down the power button until the machine shut down.
What I'm wondering is, how can I troubleshoot this? Is there something else I could have tried before forcing a shutdown? Are there logs I can inspect to see what happened? I tried journalctrl after rebooting, but it only shows logs from the current boot. I also see some log files in ~/.local/share/xorg/, but I'm not sure if they're relevant, or what to search for.

The following logs can help you debug your system from the last boot:
journalctl --boot=-1 | less
tail /var/log/syslog.1
tail /var/log/kern.log.1
tail /var/log/debug.1
tail /var/log/Xorg.0.log.old

Unfortunately, I didn't have logs persisting across boots. I've updated my journald configuration so if it happens again I'll have a better chance of getting insight into the issue.

Debian keeps logs by default. I assumed Ubuntu did as well. I think you should add your configuration change to the answer.
