Hi Antonio,

To confirm....I have tried the driver on the link you provided...(in
fact that was the driver I was trying!) but thanks!

The driver detects the Video Adapter but the integrated LCD panel still
doesn't work.  when I try to run X screen flashes several times and ends
up with Mode Pool Empty.  The LCD still detected but says max res 0x0
pref 0x0.


Xorg.log reports:
(EE) Screen(s) found, but none have a usable configuration.  

I believe that is due to lack of EDID information for the integrated LCD
Screen.  Modelines /Modes and HorizSync/VertRefresh lines dont appear to
override it.

here is the output from I from get-edid:

get-edid: get-edid version 2.0.0

The EDID data should not be trusted as the VBE call failed
Error: output block unchanged


As I said in my last post if I connect a monitor to VGA port and configure X to use it - the EDID is detected and screen is configured correctly.  

Many thanks for your help.
