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?
