Below is what happens when trying to use gnu screen. Essentially, it all works fine until I su as another user. then I get a Cannot open your terminal '/dev/pts/7' - please check.
error
l413:~$ ssh [email protected]
[email protected] password:
sbird@example:~$ screen
[screen is terminating]
sbird@example:~$ su - gradplan
Password:
gradplan@example:~$ screen
Cannot open your terminal '/dev/pts/7' - please check.
gradplan@example:~$
How can I login as sbird, su to gradplan, and still use screen?
