[Bug 1294514] Re: [Toshiba Satellite P850] Keyboard backlight does not work


Eric Goulet, thank you for reporting this bug to Ubuntu. Saucy reached EOL on July 17, 2014.
See this document for currently supported Ubuntu releases: https://wiki.ubuntu.com/Releases

upstream developers to examine the issue.

If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:

  [Toshiba Satellite P850] Keyboard backlight does not work

Status in “linux” package in Ubuntu:

Bug description:
  Immediately on boot, the backlight is lit. Switching around ACPI
  settings doesn't seem to help. Booting into Windows then putting it in
  a state of hibernation, the backlights will work upon the next Ubuntu
  boot... but only that next boot.
