[Bug 327661] Re: brightness controls on Lenovo Thinkpad x61 broken in linux-image-generic 2.6.27-11.27

** Description changed:

  The brightness controls on my Lenovo ThinkPad x61 (model 7675-CTO)
  running Ubuntu 8.10 on amd64 are broken in the latest intrepid update
  kernel (2.6.27-11.27). Neither using g-p-m via the volume fn-keys nor
  manually manipulating /sys/class/backlight files works.
  
  Brightness controls worked in 2.6.27-9.19, the previous kernel I had
  installed.
  
  Booting with `acpi_backlight=vendor' as suggested in lp:311716 results
  in video corruption (diagonal black lines across the screen in X) and
  still does not fix brightness controls.

+ Hi All,
+ 
+ On X61 (type / model : 7673-4NG) the same problem occurs, also after a kernel update.
+ I am running Ubuntu 8.10. The menu works fine  when I hit the brightness keys: the bar goes left and right. However, there is no adjustment to the brightness.
