We found half the problem and half the solution…
The 69000 graphics chip/BIOS assumes
there is both a CRT and LCD, thus it limits the resolution
to 640x480. Under Windows the results is the same however
windows can scroll the desktop. Windows has an option
to disable the LCD, how can we achieve the same thing under
Photon 2.0. The BIOS has no option to select the default ;-(
I looked the graphics DDK (luckely the 69000 driver is
part of the kit), but could not find anything related to LCD/CRT.
Does it mean I may have to fiddle with the driver to add

When setting the resolution to anything above 640x480 the
screen resolution stays at 640x480 but the desktop switches
to 800x600 (if that is the resolution requested).
It appears the hardware isn’t really switching resolution but
everything else thing it did.
The board is custom made (but nothing fancy), it uses a CHIPS
graphics chip. I have tried with chips_hivq and vesa with the
same results. Since even VESA has the same problem, does
it mean the problem is in the video BIOS not swithing properly?
