xvfb

Staffan Gustavsson — Fri, 17 Nov 2000 09:41:16 GMT

Hi everyone!
I'm usually an Windows NT guy but finally I got my hands on a unix box with HP-UX 11 on. Since I have a java app that relies on a java class lib that seems to need a screen to run. It not that fun to have a NT machine attached to our cluster just to have these java processes tunning....
I got some hints to use xvfb - virtual frame buffer to simulate a screen on the server. Where do I find that one? Distributed with HP?And how to use it? or are the anything else around to solve this?

xvbf : is not officially supported by HP, however it does run on both 10.20 & 11.xx O/S's

If you need a pre-compiled binary post your email and I can provide it, otherwise use the web to locate the source etc etc .

On it's way ... as to problems with install ? :

fine on 10.20, may have to force it on 11.xx as it's a 10.20 binary. However it works fine on 11.xx in the UKRC. Good luck.

Hello Staffan,

the functionality you are looking for is delivered by "VNC",
which is
a) freeware,
b) supported by HP (well, indirectly: HP supports it for
the XP256/XP512 administration)
You get it from
http://www.uk.research.att.com/vnc/

HTH,
Wodisch

Try the following FTP site:

Address: hprc.external.hp.com (192.170.19.51)
userid: xgraphic
password: xgraphic
Filename: 11.00/Xvfb-11.depot.gz

This is an (unsupported) installable SD depot. You will need to look at the /etc/rc.config.d/xvfb config script, and make sure it doesn't conflict with any other Xservers on the system (ie, if you have an X Print Server running, or if you have a local X display running, you will need to make some changes). Also, you will need to make sure the RUN_X_FONT_SERVER is set to "1" in /etc/rc.config.d/xfs.

I hope this helps :)

No need, HP started officially supporting it as of June 2001 .... just install
the latest Xserver patch for your O/S.

I have installed the xvfb utility with PHSS_23546. I have been successful in getting it to launch but I am receiving an error once I execute an application which requires a display (using x3d display driver).

The application which I am launching is reporting the below problem.

X connection to ancho:10.0 broken (explicit kill or server shutdown).
X connection to ancho:10.0 broken (explicit kill or server shutdown).

Any suggestions on what is happening and how to fix it?

"using x3d display driver" could you explain this ?

So you are running xvfb on a hpux system without a graphics head, what DISPLAY identifier did you configure xvfb to use ie hostname:5 , 10 etc ?

in the terminal window you are running the application from echo $DISPLAY returns ? or where and how are you kicking off your applcation and have you set the DISPLAY variable to match that of xvfb ?

Other than that could this be linked to hostname resolution ie <>
does xclock -display :# work ? where # is the screen identifier you configured xvfb to start on.

any further clues in /var/X11/Xserver/logs/* ?

ps it might be better to start a fresh post in future !
