I would like to have a remote linux host export the display back to the X2Go server, which would then forward it to the Windows 7 client.<br><br>Starting a new X2Go session, this works on the local host:<br><br>[user@localmachine ~]$ echo $DISPLAY<br>:84<br>[user@localmachine ~]$ xhost +<br>access control disabled, clients can connect from any host<br>[user@localmachine ~]$ xclock<br># note - the xclock starts without problems<br><br>But on a remote host, I found I could not connect to that display, even with "xhost +" already set:<br><br>[user@remotemachine ~]$ setenv DISPLAY localmachine:84<br>[user@remotemachine ~]$
xclock<br>Error: Can't open display: localmachine:84<br>[user@remotemachine ~]$<br><br>As an experiment, I tried setting the DISPLAY on localmachine to use the hostname, after which it could not connect to the display:<br><br>user@localmachine ~]$ setenv DISPLAY localmachine:84<br>[user@localmachine ~]$ xclock<br>Error: Can't open display: localmachine:84<br>[user@localmachine ~]$ xhost<br>xhost: unable to open display "localmachine:84"<br><br>I'm probably missing something obvious, but don't have any idea what is misconfigured.<br><br>Thanks!<div><br></div></div></body></html>
