Gentoo Console Scrolling

Hi, very simple question.  Just wondering what button I use/how I can preferably scroll up through a console session because i'm missing the text on boot; otherwise does the bootup information output to a text file somewhere?

look in /var/log/bootlog to see boot log messages

you can also type dmesg after boot, but the output of this is overwritten over time.

Hi mike_mian.  That file doesn't seem to exist.. Any ideas?

dmesg works good Anonymouslemming.. Do you know how long it takes to get overwritten or is it just a matter of data?

So there's just no way that you can simply scroll back up through a console session? Once it's disappeared on the screen, it's lost unless it's been logged?

No, no way.

dmesg command kernel ring buffer, by default, it is 16K and it's also written into the /var/log/dmesg.
This file will regenerate everytime you reboot. Or it will be overwirtten when it grows bigger than 16KB,
I mean the old message will be pushed out by the new messages.

For the boot messages history, they are in /var/log/boot.log.X (X stands for 1, 2, 3, 4)

sorry I miss-typed

should have been /var/opt/boot.log

see wesly's answer re dmesg

wesly_chen: that file doesn't seem to exist.. There's xorg files but no boot files in that folder?
mike_mian: that file doesn't exist either.  Anywhere else it could be?

wesly_chenCommented:
How about /var/log/boot.msg?
Could you post /etc/syslog.conf  for the location of the log files?

are you looking for something like Shift + PageUp ?  This will let you see what ran off the screen in any of the virtual consoles.  I don't know if it goes back to dmesg stuff though, it may have a limit like a buffer to how far back it can read.

wesly_chen: neither of those exist either.

the closest thing to syslog.conf was sysctl.conf which only seems to have a few lines of networking stuff...

arosboro: Thanks that might be it, when i'm home next i'll try it and post the results.
