Title:
gnome-terminal with screen interprets mouse wheel events as up/down
To manage
this is a huge headache for running vim in the gnome-terminal: the mouse
scroll generates a sequence of key up or down strokes that are
indistinguishable from the real keystrokes. having a very sensitive
mouse scroller will inevitably produce unwanted scrolls to wrong place
while, for instance,
I've been using this in my ~/.screenrc to tell screen not to switch to
the alternate screen, so I can use my scrollback:
termcapinfo xterm|xterm-256color ti=\E7\E[?47l:te=\E[H\E[2J\E[?47l

personally out of here (I'm not an Ubuntu developer but a gnome-terminal
one; I'm happy to join again if an
No, this escape sequence doesn't change anything.
One more clarification: problem appears only when output on the screen fills
all rows, i.e. when you output at least one screen of rows.

gnome-terminal / vte changed its behavior around that time. There was
also quite a bit of confusion caused by a downstream ubuntu patch and
removal also around that time.
I'm not sure what's 14.04's behavior, but in newer Ubuntus (e.g. 16.04)
you can disable alternate screen scrolling with the
