To begin with, I am on Lubuntu, so I can benefit from the latest screen patches that will enable vertical splitting of windows with no need to compile from source. (It really took ages...)However, despite reading the manual thoroughly a few times, there was no indication how to get the split ratio to something else but 50:50.So I opened xterm, launched screen, pressing Ctrl+a| to split the window vertically in a 50:50 fashion.Good, but what if I want a 70:30 ratio for a change? Sometimes I might need this, when I'm working deeply in the hierarchy of subdirectories on the left hand side, and just doing something rather trivial (that does not require this width) on the right.Curiously enough, even the official manual will only tell about modifying the height, but what I need is the width. Even more curiously, I read something about passing a -h/-v parameter to the resize command on the command line inside screen. (As I'm writing this, you won't find these parameters explained in the manual.) My GNU screen 4.02.01 does not seem to accept either of these two options; only a :resize <value> (with value being a signed integer number) is possible, which, as mentioned, will only ever modify the height, but not the width.Perhaps modifying the width when the window is split vertically is not intended in the first place?Well, it would come in handy sometimes, that is for sure.
