If I ssh into a machine as root, then su to a non-root user, then try to run screen, I get this error:
Cannot open your terminal '/dev/pts/0' - please check. I also get this error if I log into my local machine as root, then su to a non-root user and try to run screen. However, if I either ssh into the remote machine, or log into the local machine, directly as the non-root user, screen works fine. Both the local and remote machine are updated with the latest packages from Debian, both unstable and testing. It's seems that, somehow, when I su to a non-root user, something changes that prevents screen from working. Any ideas? Sean O'Dell
