[Bug 658198] Re: Fn key control of backlight broken after upgrade to 10.10

[Michael Doube]

Bug not present if I boot with last 10.04 kernel, which was left as an
option in my Grub menu.  Reassigning to Linux as a kernel issue.

** Package changed: acpi-support (Ubuntu) => linux (Ubuntu)

** Tags added: apport-collected

** Description changed:

  Binary package hint: acpi-support
  
  After an upgrade to Ubuntu 10.10 the previously natively-supported Fn
  key control of backlight brightness is gone.  I can control backlight
  with xbacklight, as before.  This seems to be a regression, related to
  bug #173652.
