[Bug 336923] Re: Need LVDSout quirk for Intel 945GME <8086:27ae>

[Geir Ove Myhr]

Thank you for testing and reporting back so promptly. It is evident that
you have researched this well before reporting this bug, and that really
helps. All the necessary information is now included and a developer can
look at this bug. He/she may ask for more information if some
information that I didn't think about is needed.

Btw, I read somewhere that the intel driver assumes that all the mobile
chipsets (all the ones with M in the chipset name, like 965GM, 945GME,
855GM, GM45, etc.) have an LVDS connected as they are meant for laptops
and are used for that in the vast majority of the cases. I think the
current recommended resolution is to quirk out models that don't adhere
to this, but I'm not sure.

** Changed in: xserver-xorg-video-intel (Ubuntu)
       Status: Incomplete => Confirmed

** Tags added: 945gme intel intrepid jaunty xorg

** Tags added: amd64 i386

** Summary changed:

- Need LVDSout quirk for Intel 945GME <8086:27ae>
+ [i945] Need LVDSout quirk for Intel 945GME <8086:27ae>

** Description changed:

  Working with a Disklessworkstations.com 1520 PXE Atom thinclient.
  
  There is no LVDS output on the thinclient, but it's inclusion on boot of
  Ubuntu causes the client to come up at 1024x768. In System > Preferences
  > Screen Resolution, the the monitors appeared with "Mirror Screens".
  LVDS needs to be quirked out entirely.

  I can confirm that using the following in an xorg.conf works properly:
  
  Section "Monitor"
        Identifier "LVDS"
        Option "Ignore" "True" 
  EndSection
