Boot messages / kernel log

[PredatorCK]

Probably quite stupid question, but I can find the kernel logfile of the last boot in
/var/log/dmesg, but these are not all messages (especially error messages) which are displayed when starting the box, so where is the rest...???

Oh, and I saw once that someone basically stopped the messages on startup and released them again afterwards with a certain shortcut combination, those would be helpful as well...

THX in advance

so where is the rest...???

/var/log/boot
/var/log/messages
/var/log/deamon.log
/var/log/kern.log

and off course lots of applications have their own logfiles.

Some messages are only echoed, there's an option somewhere that you can set that logs more (sorry I don't know where).
The magical shortcut combo you're looking for is the key named <scroll lock> (or somesuch), then to move up, down press <shift><page up>,<shift><pagedown>, to release press <scroll lock> again.
