I've updated my Lucid Installation to the latest Maverick alpha and
downloaded the newest packages. This *does not* help for me. The boot
splash shows up after grub but the screen still goes blank after a
fraction of a second.

I have a Lenovo U160 with Core i7 920.

> Hi all,
> On my new Thinkpad X201 with Core i5 and integrated Arrandale graphics with lucid i get a blank screen (no backlight) as soon as the i915 kicks in during boottime. Booting continues, i can hear the loginsound, but the display stays dark. External screen shows a picture, although with wrong resolution. Booting with the i915.modeset=0 results in working graphics, but only X with vesa. I tried several kernel-versions, including karmic livecd and the newest daily build from the kernel mainline ppa, both 2.6.33 and 2.6.34, all to no avail. The only kernel that works is from this ppa (https://launchpad.net/~csurbhi/+archive/karmic-stable) from bug #515246, but I couldn't isolate why. This could be a duplicate of that bug, but it has been marked fixed, but still remains with me.
> The problem seems to be that the i915 cannot initialize the internal display properly. Following snip from syslog:
