Bonjour,

Comme je ne sais pas trop où me tourner je vous soumets le problème et la
réponse de Chris Wilson de chez Intel :

The U160 requires this hack:

diff --git a/drivers/gpu/drm/i915/intel_bios.c b/drivers/gpu/drm/i915/intel_bios
index fb5b4d4..53ff16f 100644
--- a/drivers/gpu/drm/i915/intel_bios.c
+++ b/drivers/gpu/drm/i915/intel_bios.c
@@ -267,7 +267,7 @@ static int intel_bios_ssc_frequency(struct drm_device *dev,
         case 4:
	                return alternate ? 100 : 96;
			        default:
				-               return alternate ? 100 : 120;
				+               return alternate ? 120 : 100;
				        }
					 }

When I work out why, I'm liable to get very angry.
