[Bug 331357] Re: dell lcd brightness strange behaviour

[Ivan Zakharyaschev]

I have a similar problem on linux 4.4.119, but not on linux 3.10.32:

smbios-lcd-brightness --value=1

has a visible effect on linux 3.10.32, but not on linux 4.4.119, though
the saved value is modified indeed.

Do you have some ideas?

python-module-smbios-2.3.3-alt1.0.g4fec2ad.noarch
libsmbios-2.3.3-alt1.0.g4fec2ad.x86_64
smbios-utils-2.3.3-alt1.0.g4fec2ad.x86_64

Bug description:
  Latitude E6400
  the command
  sudo dellLcdBrightness -v [0-f]
  does not modify the real LCD brightness, but only the value stored in the BIOS, as after executing
  sudo dellLcdBrightness
  I can see that the value is changed accordingly to the one I selected in the previous command.
