ATI Fire T2 Graphics on HP C8000 - PseudoColor?

[Matt Wardle]

I cannot get the ATI Fire T2 Graphics on HP C8000 to run PseudoColor. Our application needs 8 bit PseudoColour and tests the visual before starting.
In /etc/X11/XF86Config, I try and set it, but after I have restarted the Xserver, logged in, do a xwininfo or xdpyinfo it still says TrueColor (and of course the application doesn't work).

How can it be 8 bit TrueColor anyway?

It says in /var/X11/Xserver/logs/Xf86.0.log


(**) fglrx(0): OpenGL Overlay enabled
(**) fglrx(0): TrueColor video overlay visual: off
(**) fglrx(0): Default visual is PseudoColor


Here is the XF86Config file:

xwininfo and xdpyinfo are attached.

Thanks,
