GNU Screen seems to freeze. Unable to enter user input.
I was using GNU screen and when I pressed the screen it became unresponsive. I can execute all the GNU screen commands, but can't enter user input. I don't want to kill this screen as I have important work and I don't want to lose it.
If you exit screen, by typing exit, you lose that session. To detach it, type Ctrl-a Ctrl-d (most commands in screen start with Ctrl-a, this overrides the Ctrl-a command normally used when you want to jump to the start of a line).
To open a new window, press Ctrl+A, release, and then press c. This creates a new window on top of your existing window.
In the commands below, replace Ctrl with whatever your escape key is for screen commands.
Try Ctrl+a q, which is the sequence to unblock scrolling.
Ctrl+a s is the sequence that blocks scrolling, which makes screen seem like it freezes.
