How to set unlimited scrolling on a TTY?

Question

On a TTY ( ctrl+alt+f1 to f6 ), I use Shift+page up to scroll up and Shift+page down to scroll down. But the problem is, the scrolling is limited to certain number of lines.

How can I get unlimited scrolling on a TTY ?

Answer 1

First, you buy unlimited memory. Take a look at the kernel paramter fbcon=scrollback:Nk where N is the desired buffer size is kilobytes. The default is 32k, so increase it from there.

To increase framebuffer console memory :

gksu gedit /etc/default/grub 

Now edit and change GRUB_CMDLINE_LINUX="" to GRUB_CMDLINE_LINUX="fbcon=scrollback:<value>k" .

Now, update grub:

sudo update-grub

And restart your computer
