a problem with GNU Screen
 

Hi slackware folks,
I met trouble like this:

--
qw@slk:~$ screen -ls
There are screens on:
2737.cal (Detached)
1498.knp (Attached)
2 Sockets in /home/qw/.screen.

--
qw@slk:~$ screen -d 1498
[1498.knp detached.]

--
qw@slk:~$ screen -ls
There are screens on:
2737.call (Detached)
1498.knp (Attached)
2 Sockets in /home/qw/.screen.

qw@slk:~$
--

I cannot really detach it.
I am using Slackware.

qw@slk:~$ uname -a
Linux slk 2.6.33.4 #3 SMP Wed May 12 23:13:09 CDT 2010 x86_64 Intel(R) Core(TM)2

Try to attach with screen -x and then detach normally

Your method works for me, but I usually use
There is also
--- rod.
