How do I disable scrolling in Urxvt?

Question

Is it possible to disable scrolling in urxvt when we use with tmux? The problem I have is that tmux clear-history command won't clear the urxvt scroll buffer (Shift+Page Up), hence we always have history in the console. The only other way isto detach Tmux and reset the Terminal to clear this content. Would it be possible to make urxvt to have no scroll so that I can handle everything in tmux which is more logical when you use tmux?

Answer 1

You can set the following in ~/.Xdefaults to force Urxvt to not keep any history:

URxvt*saveLines:0

This will render Shift + PgUp as a no-op, even in Tmux.
