Dear Abe @ Debian, Surely I am glad that screen exists, and I apologizes if my reportbug got bit of emotions in there.
- I understand the problem basically depending on su and sux. The problem of permission/dev is definitely very difficult to the solved, or would imply lot of change. I wished that the users do not find this error message anymore somehow, with maintaining a secured box (some chmoding or root power would easy but... ). The issue is not seen under X11 regular use, and luckily, -very luckily, screen works . Indeed when users do some su or sux or ssh sometimes, the issue can occur. That's bit sad. Well, one day, If you or someone code a fork to screen that can solve the issue, please do not hesitate to let me know, because I a fan of screen, can't live without since I admin regularly boxes over SSH and the net wire. May Tux be with You always, Kind regards, Y.
