<p>As was already hinted at in [1], if you need more help, you
probably need describe better what you system(s) configuration is
like such as are you only using w2web and xcrysden in Ubuntu
locally (physical Linux box or in a virtual machine) or are you
connecting to them remotely?</p>
<p><br>
</p>
<p>If you have defined $DISPLAY, w2web might just pick that up. If
you know Perl, I suggest you have a look at
$WIENROOT/SRC_w2web/htdocs/util/viewcrys.pl.<br>
</p>
<p><br>
</p>
The xserver that you mentioned, is it setup for X11 forwarding? If
you are not using w2web locally with an offline setup [2], but are
instead using an online setup were w2web is connected to the
internet (or a local network) and is unable to get xcrysden to open
in w2web, are you able to get it to open instead using an ssh
connection with X11 forwarding? Refer to [3,4].<br>

When typing echo $DISPLAY into the terminal I am seeing :0. I
still continue to see "requires X-Windows System..." when I try
to view the crystal in w2web. Is there a way to set the DISPLAY
variable inside the w2web process so that it may work there as
well. Where do you recommend I set DISPLAY?</div>

<p>Maybe there is still a problem with your XCRYSDEN_TOPDIR,

<p>Regarding DISPLAY, maybe the following link to a xcrysden

Thank you for the response. That did resolve the issue. I am
now seeing "Requires X-windows system..." in the view struct
portion of w2web. I do have an xserver runner, as I am
running on Ubuntu. Is there a place where I need to set
DISPLAY? </div>

<p>Most likely you just need to kill and restart w2web.</p>

I unable to view crystal with Xcrysden in w2web
