Details:
I run my X session in screen, so that I can later attach to it inside the X
session itself. However, this sets the STY environment variable, so when I go
to use screen inside a terminal, it just quietly exits (or opens a new window
in my X screen?), with no indication in my terminal what actually happened.
Expected behaviour is that it realises it's not inside the X screen, and
behaves the same way as if STY was not set: create a new screen session with
the application.
Also, I observed that inside a screen session, if you change users (eg, with
su or sudo) and STY remains set, screen fails with an error:
/root/.screen/3192.X: No such file or directory
