Subject: Re: KMS Framebuffer on Intel N2600 (GMA3600)

Hi Alan,
I wasn't be able to make the Linux Framebuffer run on my kernel, even if the kernel config seems to be correct.
I have decided to give a try to ubuntu-server because many users report to make their netbook screen work with cedarview-drm driver.
To be short, I installed ubuntu-server, installed a non-pae kernel (3.2.0.33), installed cedarview-drm package and configured grub with video=LVDS-1:d.
Framebuffer is up and running now with 800x480 resolution. I haven't investigated yet why ubuntu driver works and the one I built wit the 3.6.6 kernel not.

Thanks again for your support.

Regards,
Samuele.

Could help explain why there is no backlight. Initial eDP support got
added to the driver very recently so it might work but it should still
have decided itself you have eDP given a current kernel.
