Xvfb issue

Matthew White_3 — Mon, 16 May 2005 16:52:16 GMT

Greetings,

I'm running Xvfb on one of my servers, but it doesn't seem to be configured correctly. When it try to test it, I get this:

host1:root# xwd -out junk -root -display host2:19
Xlib: connection to "host2:19.0" refused by server
Xlib: No protocol specified

xwd: unable to open display 'host2:19'

I've been racking my brain, but Xvfb is poorly documented. Does anyone have any ideas?

'host2:19'

That is not a valid hostname/display for xvfb

xvfb is a X server that allows products like Oracle reports to run without the presence of an actual graphics card on the hpux server.

Its startup parameters are set in /etc/rc.config.d/xvfb

There could be something wrong in there and you may get away with copying that file in from another working server.

Also see that the DISPLAY variable is set correctly in whatever program is actually using the xvfb. If its an oracle startup script, thats imperitive.

Hi Mathew

I use DISPLAY in 2 ways

$export DISPLAY=MY_PC_IP_ADDRESS:0.0

to run as root
su (become root without -)
then whatever X programs you want to run.

First you must run your X server program (I use cygwin) on YOUR PC.

Thanks
