I think the X connection can not be closed. But you can run IDL in a VNC session. We were discussing it two years ago, I copy-paste my old advice:
The graphical counterpart of screen is Xvnc (vncserver). I use it with
openSUSE 11.2, but I think other distros are similar:
- login to the remote host
- vncserver
this prints something like:
...
New 'X' desktop is remote:1
...
- logout
On your local machine:
- vncviewer remote:1
- open a terminal, start your job, ...
After exiting vncviewer, you can turn off your local machine.
regards,
Lajos
