Comment 11 for bug 297245

I have a hunch that it has to do with the LCD panels manufactured by AUO.
I'm no developer, and this is the first time I've tried to interpret Xorg.0.log, but from what I can tell I believe that the line
[quote](II) VESA(0): Manufacturer: AUO Model: 8174 Serial#: 0[/quote]
refers to the LCD used in my Dell Studio 1535. I've confirmed that AUO is an LCD manufacturer. Here is their website. http://auo.com/auoDEV/?ls=en

This looks as though I should be able to create a modeline like this...

[quote]modeline "1280x800@65" 83.46 1280 1328 1360 1377 800 803 809 810 -hsync +vsync[/quote]

But even by deleting all other modelines from xorg.conf and inserting the new one, I still only get 1024x768, 800x600, and 640x480.

There is then a section of xorg.0.log that reads as follows...

[quote](II) VESA(0): EDID vendor "AUO", prod id 33140
(II) VESA(0): Searching for matching VESA mode(s):[/quote]

What comes next is longer than the forums will permit but can be read on launchpad under the bugreport that I referenced in my prior post. The main point is that there are no values for any resolution other higher than 1024x768.

So I'm assuming that this LCD manufactured by AUO is not reporting that it is capable of a 1280x800 resolution. Is this because the Intel driver needs to be updated to support the AUO LCD or is it that Dell created a laptop with a budget LCD that doesn't really support resolutions that they advertise?
