Where can I find the kernel logs?
For those with server/no monitor access you can access the logs using tail
tail -f /var/log/kern.log
I guess you can also use gnome's application:
System -> Administration -> Log File Viewer
There is a nice graphical viewer for the kernel logs by the people at KDE.
KSystemLog
dmesg command can also be used to display the kernel log. It can be used as follows.
dmesg -k -w
