So, I can't use any X application because of :
Xlib: connection to "@IP:0.0" refused by server
Xlib: No protocol specified

CDE seem installed correctly :
lslpp -l | grep X11.Dt
X11.Dt.ToolTalk 5.3.0.0 COMMITTED AIX CDE ToolTalk Support
X11.Dt.adt 5.3.0.0 COMMITTED AIX CDE Application

but CDE seem not working good, I have only :
ps -ef |grep dt
root 319626 307262 0 10:36:37 pts/1 0:00 grep dt
root 327802 192692 0 10:18:26 - 0:00 /usr/dt/bin/dtlogin

Did you try "xhost +" from the console?

Yes, it's the same from console. I suppose it's console because i open terminal from HMC.

I have no graphic card, and then no /dev/lft0
I try to tell to CDE skip search graphic card when starting by setting DT_NO_DISPLAY_CHECK but don't know what to do.
trying DT_NO_DISPLAY_CHECK=1 and true failed

Not sure I'm on the good way ...

I apologize if the following answer is inappropriate.

Am I correct, that you seek to use X without a graphics card?

If I understand your situation correctly, a few concepts may be helpful.

X is a communications protocol for sending graphical presentations
(http://en.wikipedia.org/wiki/X_server#Design_principles_of_X)

The X server must be running on the machine whose monitor you use.
Clients can be running anywhere limited by communication bandwidth.
Each client must be informed where to send its graphical directions,
by setting $DISPLAY to <host>:<server>.<screen>.

If not set, most clients will default to DISPLAY=:0.0 which is normally
equivalent to 127.0.0.1:0.0 (the first screen controlled by the first
X server, running on the local host).

When started, the X server must be informed about the graphics card and
monitor that is installed for use. Most X servers default to a VGA graphics
card and 640x480 VESA monitor.

<IMHO>
Though XGGI (http://www.stacken.kth.se/~mackan/ggi/xggi/) exists as an
X server that requires no graphics card, it is not generally practical.
</IMHO>
