[gentoo-user] Can the text based consoles be made scrollable?

[Andrew Lowe]

Hi all,
	I'm having a bit of trouble with KDE after a emerge world. Now when I 
log into my box at a text console, no X running at all, and attempt to 
do "stuff" to debug the problem the output scrolls off the top of the 
screen. Is there a way to make a standard bash shell/terminal/thingy 
scrollable so I can go back up though the output and review the results 
of my fiddles?

	Regards,
		Andrew

Did you tried shift + pgup? it will let you scroll a bit up. Opposite for
shift +pgdown

If you need some more features, you might want to consider using a
terminal multiplexer like tmux or gnu screen, which have their own
scrollback buffer.

Both tmux and screen will suite the OP's needs, s/he should also consider
piping their output to more or less.

ps auxf | more

or

ps auxf | less

My personal preference is to use less, I find it to support my Vi/ViM habits
more appropriately.

If you have logged in a console you should be able to scroll up/down.  
However, if you are still looking at the login prompt then on my machines at 
least you cannot scroll up to see what happened during boot.

	Thanks to those who suggested Shift PgUp/PgDn, it worked and I'm now
sending this from within KDE. The post on "screen" was also a good one,
I'll have to file that away for later use.

The number of lines scrolables is defined in a kernel param.

After investiguating :

the kernel param is : CONFIG_VGACON_SOFT_SCROLLBACK_SIZE

it seems that you can customize this in grub kernel line : 
fbcon=scrollback:128

And vimmanpager :-)

A couple of months back, there was a discussion in this here list about
vimmanpager, and how there is no eselect module to specify which pager to
be used by man. Someone kindly provided such module for me, but I forgot
who exactly :-(

In my systems, I even created a symlink /usr/local/bin/less that refers to
vimpager.

Rgds,
