TLDR; what log files are important when troubleshooting an issue in TW.
I'm investigating an openSUSE TW KDE machine that's locking up daily while idle. Screen frozen, keyboard lights not responding, can only force off by holding power button. Even the instant reset button on the case doesn't work.
Systemd journal has seemingly nothing of significance. In a hunt to find other logs, I found in the docs a list of log files . However /var/log/warn doesn't seem to exist in TW, and the others don't seem relevant, so I'm continuing a search.
/var/log/warn content will be in the systemd journal. You can activate traditional syslog if you want, but the contents should be the same.
Sadly, in such a crash must often you find nothing in the logs because the machine went down before anything could be written. For instance, the disk may become inaccessible (kernel crashed), or the hard disk had no time to actually write the log.
Thus to investigate issues one method was to have the kernel write directly to the serial port, which goes to another machine. Works best if it is an actual hardware rs232 serial port, not one via usb - because the true serial port is directly accessible at very low level. Like when looking at the human mind functions which are described as the reptilian mind. Deep inside :-D
If there is physical Ethernet port (not wireless) netconsole may be an option.
Things to investigate are video issues, heat issues, memory issues - not in any particular order.
