[Intel-gfx] Help-On frame Buffer

[Bruno Prémont]

Hi,

You should look at KMS (Kernel Mode Setting) with i915 driver that you
find under DRI. (CONFIG_DRM_I915 + CONFIG_DRM_I915_KMS)
KMS can also be manually enabled/disabled with i915.modeset kernel
parameter when i915 is built-in.

VESA only knows a few standard predefined modes but not the wide
resolutions currently seen. It's based on some BIOS code and can only
set resolution at early system boot, does not support s2ram (S3) nor any
acceleration.
