Yesterday, I ran a bash script for about 10 hours. When I went to use the computer, it locked up.I have an Eee PC with Debian.The screen was still visible, but the mouse or keyboard had not effect.I tried CtrlAltDelete, CtrlAltBackspace, CtrlAltF1, but to no effect.The hard drive light showed no activity.How can I determine what went wrong? What logs can I check?
How to determine why my computer crashed?
debian;crash
You can find all messages in /var/log/syslog and in other /var/log/ files. Old messages are in /var/log/syslog.1, /var/log/syslog.2.gz etc. if logrotate is installed.However, if the kernel really locks up, the probability is low that you will find any related message.It could be, that only the X server locks up. In this case, you can usually still access the PC over network via ssh (if you have installed it). There is also the  Magic SysRq key to unRaw the keyboard such that the shortcuts you tried could work, too.
