[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

Is this still reproducible in a supported release? If so, could you
please test the latest upstream kernel available from the very top line
at the top of the page (the release names are irrelevant for testing,
and please do not test the daily folder) following
https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional
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:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested exactly shown as:
kernel-fixed-upstream-3.18-rc4

This can be done by clicking on the yellow circle with a black pencil
icon next to the word Tags located at the bottom of the bug description.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

** Changed in: linux (Ubuntu)
       Status: Confirmed => Incomplete

Title:
  [Toshiba Satellite P850] Keyboard backlight does not work

Status in “linux” package in Ubuntu:
  Incomplete

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.
