Getting this with 1.91 on Arch, it likes to happen during package updates for some reason.
I found a hacky workaround - add this to your $PS1: \[\e[?1049l\e[?2004l\e[?1006l\e[?1002l\e[?1001r\e[?1l\] It'll fix it as soon as you get to a prompt. Given how randomly it happens, I believe there is a real bug in Terminator; but if you want to force the broken state, just open 'mc' and run 'pkill mc' from another terminal, your scrolling will be broken. A way to debug this kind of thing is to run e.g 'mc > trace.txt'. Then type 'exit', hit return, and mc will quit. You will get all the escape sequences from mc in trace.txt to inspect. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to bash in Ubuntu. https://bugs.launchpad.net/bugs/1566437 Title: Scrolling randomly stops working Status in bash package in Ubuntu: Confirmed Bug description: Usually, scrolling in the terminal window works as expected, which is like this: - the terminal window has a scrollbar - Assuming there are more lines (of commands you have typed + their output) than fit in the window, you can scroll up and down both by dragging the scrollbar and by using the mouse wheel However, at random times, the Terminal starts behaving like this: 1 - the scrollbar's "handle" is as high as the whole scrollbar, as if the existing lines didn't exceed the height of the window, even if that is not the case 2 - you can't scroll by dragging the scrollbar (which is consistent with 1) 3 - the scrollwheel behaves like the up and down arrow keys, that is, it scans through previously typed commands in your history. I have no idea what triggers the nonsense behavior. It seems to start happening randomly.
