i just built a kernel for my ubuntu 10.10 system and forgot to include the following patch which is what i've needed to avoid the dreaded black screen of death:

diff --git a/drivers/gpu/drm/i915/intel_opregion.c b/drivers/gpu/drm/i915/intel_opregion.c index d2c7104..a1a5d03 100644 --- a/drivers/gpu/drm/i915/intel_opregion.c +++ b/drivers/gpu/drm/i915/intel_opregion.c @@ -152,6 +152,8 @@ static u32 asle_set_backlight(struct drm_device *dev, u32 bclp) struct opregion_asle *asle = dev_priv->opregion.asle; u32 max;

+return ASLE_BACKLIGHT_FAILED; // rday + if (!(bclp & ASLE_BCLP_VALID)) return ASLE_BACKLIGHT_FAILED;

and i once again got the black screen. is this still a known and unresolved issue?
