Zencafe not appear desktop GUI (X-Windows)

Still related to the project and open the internet cafe and because I still "green" in the linux, I looking distributions are easier to service internet-cafe (in this case I) for the project. The choice fell for Zencafe 1,2 by A. Hardiena.

Afterwards I install all user with zencafe, and was successful well.
But when the server is installed zencafe, appear article:
Parse error on line 132 of section monitor in file /etc/X11/xorg.conf. The HorizSync keyword must be followed by list of numbers of run
Fatal server error : no screens found

As a beginner in Linux, I clear panicked faced this. I did not read well the guidance error earlier.
Anyway, I try to check in /etc/inittab, have written to be, "default4: desktop".

Finally, after with the calm heart and calm thoughts, was read by me once more. Then I open the file / etc/X11/xorg.conf
In line to 132, namely HorizSync line, there is written "158-72." I also confused, this is how the numbers should be replaced?

Fortunately that is I do internet-cafe, where is monitor in general was the same type. So I open / etc/X11/xorg.conf from the client computer, I was compared that setting. That is for the monitor of TriGem 17″, HorizSync is “30 -72 ” .  
Added Option "DPMS", save and restart.

Voilà! now appear desktop GUI it!

But in forum.linux.or.id that use this way:
Using another monitor that has a GUI desktop appears, replace the original monitor.

Might also. Free to use any method. :-D
