I'm having alot of problems with screen and /dev/pts/* as well. In my case, I've got /dev/pts mounted to mode 620. Now from what I've observed, in my case, screen tries to :
crw------- 1 root tty 136, 13 May 18 10:54 /dev/pts/13
it does a geteuid (root's pid) and getuid (my pid) and then it does a setreuid(root's pid, my pid) which results in
open(pty, O_RDWR)... Permission denied
And then it restores the ruid to root and euid to me. Which is obviously wrong.
Whatever.
(screen 3.7.6-1.1, kernel 2.3.0)
