How to examine the cause of system crash?

[liquid]

Sometimes, it happens to my system - 64b on i5, kde - it crashes and gives no response to mouse or keyboard. The only thing I can do is hard restart. How to examine what caused this? Which log files to search and what?

Kmenu --> System --> KSystemLog

Have you tried raw keyboard input?

Next time you lock-up hold down CRTL-ATL-SysRq (an amazing feat if you have small hands!) and type these letters:

R S E I S U B

Most of your log files are in the /var/log directory or subdirectories thereof. Look for files with recent changes. In general, dmesg is a good source of information on boot problems; syslog tells you when things like clock updates take place; xorg*.log will tell what your display manager has been up to, recently, and the logs in sub-directories like /var/log/cups/ and /var/log/apt/ tell you what printers and package managers are up to.
