How do I increase the scrollback buffer in a running screen session?

Question

Lets say I have a currently running screen session I am interacting with through putty. I\'ve realized that the scrollback buffer is too small and would like to increase it

Answer 1

There is a minimal amount of "default" buffer when you startup a 'screen' session within your 'putty session'. I use screens a lot in my work, so I can tell you that you will not have a combination of 'screen' buffer & 'putty' buffer within your 'screen' session.

Setting the default number of scrollback lines by adding defscrollback 10000 to your ~/.screenrc file is the correct solution.

By the way, I use "defscrollback 200000" in my ./screenrc file.
