[David Gerard <dgerard@xxxxxxxxx>]

Christopher - thanks very much for your post. You should be unsurprised
to hear that I updated the BIOS and it made no difference.

I say you *should* be unsurprised, on the assumption you read the rest
of the bug. Because we know for sure (a) it works with a patch (b) that
Canonical used to have and (c) Canonical has since removed.

So your request was fundamentally asking me to jump through a hoop in
the hope you could close a bug, knowing very well it wouldn't actually
fix the (completely known) problem.

But I have jumped through your hoop and it didn't work. Next hoop?

Title:
  Toshiba Portege R830-13C no backlight after resume from suspend

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Toshiba Portege R830-13C: laptop comes back from suspend, but with no
  backlight.

  I can slightly work around it with the script at
  http://www.refreshit.info/2013/03/solved-backlight-problem-after-
  suspend.html , but this is less than ideal (and I can't adjust the
  backlight after this).

  uname -a output:
  Linux lt14000 3.8.0-14-generic #24-Ubuntu SMP Fri Mar 22 19:45:03 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

  This is a regression from Quantal on the same laptop, where the
  backlight came back after suspend - stuck at full brightness, not
  adjustable (so still not 100% functional).

  [Extra information for backlight bugs will be added next.]
