The AIX X server has been enhanced to support the X Virtual Frame Buffer technology. The X Virtual Frame Buffer (XVFB) allows the X server to initialize and run without the presence of any physical graphics adapter. In the past, the X server required one or more graphics adapters in order to run and would exit with an error if none were present.

The XVFB for AIX 5.X is installed from the AIX 5.X product CDs. Install the following filesets substituting the X with the actual version number:
- OpenGL.OpenGL_X.dev – OpenGL Virtual Frame Buffer Support
- X11.vfb – Virtual Frame Buffer Software for AIXWindows
Once the filesets have installed successfully, verify that they have installed correctly by using the following command:
lppchk -v
then run:
lslpp -L | grep vfb
The two filesets you installed should now be listed…
To start the X Server with the XVFB and proper extensions :
/usr/bin/X11/X -force -vfb -x abx -x dbe -x GLX :99 >/dev/null
To restart the X Server automatically at the next reboot, add an entry to the /etc/inittab file :
mkitab “xvfb:2:respawn:/usr/bin/X11/X -force -vfb -x abx -x dbe -x GLX :99 >/dev/null”
Set DISPLAY by adding the following line to .profile:
DISPLAY=`hostname`:99.0 ;export DISPLAY
