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 ?

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
Now, update grub:
And restart your computer
