What kernel are you using?  Try 2.6.38 if you're on an older version.

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

        case 4:
                return alternate ? 100 : 96;
        default:

+               return alternate ? 120 : 100;
        }
 }
 
When I work out why, I'm liable to get very angry.

Intel i3 / 945GM/ KMS / Debian

[Christophe Gallaire]

[-- Attachment #1.1: Type: text/plain, Size: 2929 bytes --]

Hello,

My machine, a Lenovo U160, running with an Intel i3, Debian, testing stage. I
tried everything to exploit the graphics capabilities with the driver
xserver-xorg-vidéo-intel from all branches of Debian. Activated with the KMS,
black screen at boot. Without KMS, black screen at GDM login.

I am forced to use the driver "vesa". My screen is desperately poor on a 16:9
resolution.

I am not alone in this case ?
