[Info-vax] [XDM] Can't open display

[JKB]

	Hello,

	I have posted here few days ago a question about xdm. I have
	reinstall DECW$ from scratch on OpenVMS 7.3 (VAX).

	On a Unix workstation, I launch
	Xephyr -query fermat :1

	and this server tries a connection to fermat (VAX) as
	SYS$SPECIFIC:[TCPIP$XDM.WORK] contains three new files after each
	connection:

$ dir

Directory SYS$SPECIFIC:[TCPIP$XDM.WORK]

HILBERT_1.COM;1     HILBERT_1.ERR;1     HILBERT_1.OUT;1     

	If I understand, DECW$ tries to start @HILBERT_1.COM;1 and writes
	errors in HILBERT_1.ERR;1

$ type HILBERT_1.ERR
[17E 1673458252] xdm error: server open failed for hilbert:1, giving up
$ type HILBERT_1.OUT
$ type HILBERT_1.COM
$ @SYS$COMMON:[SYSEXE]TCPIP$XDM_XSESSION.COM hilbert:1  

	I have tried to start
$ @SYS$COMMON:[SYSEXE]TCPIP$XDM_XSESSION.COM hilbert:1

	and this command returns:
p1 = HILBERT:1 
p2 =  
Executing SYS$MANAGER:SYLOGIN


Executing run sys$system:decw$wsinit

Can't open display

Executing run sys$system:decw$session

X Toolkit Error: Can't open display: _WSA4:

Fatal error detected, image exiting -- final message:
no safety display could be opened
: non-translatable vms error code: 0xE4A, vms message:
%system-e-unsupported, unsupported operation or function

Connection closed by foreign host.

	Why "Can't open display" ?

	Help will be welcome,

	JKB
