Replying to [comment:6 kallisti5]:
> building the accelerant and driver and dropping into the folder may not
be a good test... a lot has changed in the image since A3. Could you test
the latest nightly from an iso or dd'ed onto a usb drive?
Sure, I will do that and post in a moment.
> That shows AtomBIOS is actually reporting a lvds mode of 1400x1050 for
this card. Is 1400x1050 the correct native resolution? We pass that value
back to Haiku as the preferred mode if a preferred mode is found.
As was mentioned before (here and on your blog), my native screen
resolution is 1366x768. That is what WinXP, Win8, and Linux used to
detect, at least. I have no idea why Haiku's LVDS queries give a different
result.
