The TTY freezes after “Ctrl-A” hotkey and “s” pressing with GNU screen
I would like to split a window horizontally.
When I type screen and then press Ctrl-A and press s, the TTY freezes.
OS version: Ubuntu 20.04.2 LTS
Device: ASUS laptop
Solution 1:
ctrl-a s in screen sends the underlying terminal a ctrl-s which causes it to stop. You can resume with ctrl-a q.
If you want split screen, you want ctrl-a S with a capital "S" not a lowercase "s".
