Re: Is it possible to scroll back and see bootup messages on console?
Hello Debian Land...
The best way to see all the messages is to not run any programs on tty1 (the first
virtual terminal - also the default terminal). You can then scroll all the way back
to the bios boot information using the shift+pageup key combination.
So long as you run no programs (or at least ones that dont take over the screen) then
you can scroll up and down as many times as you want using the shift+pageup and
shift+page up.
If you always want access to this informaiton then login to Linux using any one of the
other virtual consoles. As far as I know it using the other virtual terminals will
allow you to always got back to the information on the first one.
One further point regarding linux logo. If you have this installed and configured to
display then you can still see all the boot information.
P.s. You may or may not have to login to the machine to scroll ( I haven't tested it
by not logging in.)
Hope this clears a few things up.
