xvfb-run Command not found

[pravin_bluebird]

Hey all,
I want to run my Adobe AIR application on Fedora 8
i found that it can be done using "xvfb".

So i install X -server on server.

but it says "xvfb" command not found....

i also want some information about xvfb-run.
is there any difference between xvfb and xvfb-run...

I have successfully run the AIR application using ADL on server.
but my purpose is to run this application from PHP by executing commands..

So i found that it can only be done creating Virtual buffur on server using xvfb-run command....

can any one advice me how do i go further...

i am stuck at xvfb-run command....



thanks

You need to install xorg-x11-server-Xvfb - it should be available in the package manager. That is the X-server that supports a framebuffer for better performance. The spelling might differ on your system - I am running RHEL/CentOS 5.3.

Also, I found the command /usr/bin/Xvfb. Note the upper-case X.

Xvfb is an X server that can run on machines with no display hardware and no
physical input devices. It emulates a dumb framebuffer using virtual memory.

The primary use of this server was intended to be server testing. The fb
code for any depth can be exercised with this server without the need for
real hardware that supports the desired depths. The X community has found
many other novel uses for Xvfb, including testing clients against unusual
depths and screen configurations, doing batch processing with Xvfb as a back-
ground rendering engine, load testing, as an aid to porting the X server to a
new platform, and providing an unobtrusive way to run applications that don’t
really need an X server but insist on having one anyway.

That is from the Xvfb man page.
