If you get the following errors starting screen as a user:
No more PTYs. Sorry, could not find a PTY. [screen is terminating]
You have to change /dev/ptmx file permissions:
# ls -l /dev/ptmx crw-r--r-- 1 root root 5, 2 nov 18 23:28 /dev/ptmx # chmod a+w /dev/ptmx # ls -l /dev/ptmx crw-rw-rw- 1 root root 5, 2 nov 18 23:34 /dev/ptmx
Under Ubuntu, there was no problem. Permissions already set:
$ ls -l /dev/ptmx crw-rw-rw- 1 root tty 5, 2 2009-11-18 23:37 /dev/ptmx

man ptmxubuntu$ ls -l /dev/ptmx
