Hi,

I have deployed a XPe image for a mainboard with Intel 945gm(e)
chipset. The driver has been built with Intels IEGD driver kit 8.0,
with support for both 855 and 945 chipsets. External VGA port is
supported, and internal LVDS, connected to a LCD, display clone mode,
1024*768@60Hz.

Now we face the problem that, when our button to turn off the display
is used, aftert reactivating the display the content is garbled. The
picture can be seen, but in wrong colours, low contrast and with some
flickering noise. It just looks like a LVDS display with wrong BIOS
settings.

So it seems that the graphic chip does not wake up correctly after
this partial power down.

When using the normal XP driver that is designed for the end users
notebook PC or such, there is no problem at all. But we must use this
embedded driver, to be able to support several mainboards, and because
of the new 945gme chipset that only is used with embedded stuff, and
is not supported by the normal end user stuff.

Any ideas what I could have done wrong? Thank you for any input!
