Title:
  regression: black screen after boot, intel graphics

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  lsb_release -rd:
  Description:	Ubuntu 10.04 LTS
  Release:	10.04

  I have been using Lucid Lynx for some weeks now. After updating the
  kernel to 2.6.32-21, my IBM Thinkpad X40 became unusable. It shows the
  usual purple progress bar (albeit in 800x600 resolution, it is usually
  shown in 1024x768) when booting, and then goes all black. There is no
  hard drive activity either, and i cannot get to the console. When i
  from a live cd changed grub.cfg to show a menu, i managed to boot with
  the old 2.6.32-19, and everything is fine again. 2.6.32-21 works in
  recovery mode (with vesa driver).

  Xorg.0.log contains these warnings when on 2.6.32-21:

  (WW) Open ACPI failed (/var/run/acpid.socket) (Connection refused)

  WORKAROUND: i915.modeset=1
