[GMA X4500] Cannot set a 1366x768 resolution? :-(

[darkbasic]

Hi,
I have a Loewe Concept 26, it has a native resolution of 1366x768 pixels.
Unfortunately the max resolution which xrandr displays is 1280x720.
So I tried to make a modeline for 1366 with gtf (gtf 1366 768 60), but it gives me a 1360 modeline instead.
I tried using it, but it doesn't show any picture at all
I tried both 50 and 60 Hz.

I had already used the native resolution of this panel with a nvidia card in the past and it worked flawlessly.

How can I make it work with an intel card too?

It is impossible to use 1366x768, nearest appoach is 1360x768 which is correct.

You might want to bring this up on the intel-gfx or xorg-devel mailing lists (or file a bug report) it's possible that your panel need a quirk to work correctly.
