How to set unlimited scrolling on a TTY? [duplicate]
Solution 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
