Re: [Bug 1088992] Re: Sony backlight brightness controls not working in 12.10

 

Hello.

I have updated to the latest BIOS release for my machine, but the screen
brightness still does not change when I use the brightness controls (the
onscreen brightness "slider" moves, but the actual screen brightness does
not change).

The output from the "dmidecode" command is;
R0170D6
03/13/2012

Regards,  David Peck.

Title:
  [Sony VAIO SVE1712C5E] Backlight brightness controls not working in
  12.10

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I have recently updated from 12.04 LTS to 12.10 to enable better
  support for UEFI booting on my machine.

  Now that I have updated to 12.10 the brightness controls no longer
  work. They were working fine in Version 12.04 LTS. I have been
  debugging this problem with a very helpful person (Toz) on the Ubuntu
  Forums and it would be worth taking a look at this thread to see
  progress to date http://ubuntuforums.org/showthread.php?t=2092897

  As suggested I have created a bug report with "ubuntu-bug linux" in
  terminal.

  I am happy to provide any additional information they may help resolve
  this problem.

  Regards,  Dave.
