[Bug 76274] Re: Brightness Settings Don't Work

[Guido Conaldi]

Can confirm the same issue with my vaio S1XP.

DMI decode data:
Sony Corporation
VGN-S1XP(IT)
J0009F44

I guess my bug report:
https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/92478
and this one:
https://bugs.launchpad.net/ubuntu/+bug/103890
are duplicates.

I'm not sure quite what you mean by does it work. Please clarify.

DMI data:

Sony Corporation
VGN-S4XP_B

This is more likely a 'hal' or kernel issue:

  /usr/share/hal/scripts/hal-system-lcd-set-brightness

Currently has the following code for Sonys:

  elif [ $HAL_PROP_LAPTOP_PANEL_ACCESS_METHOD = sony ]; then
# echo {1..8}  /proc/acpi/sony/brightness
# http://popies.net/sonypi/2.6-sony_acpi4.patch
echo $((value + 1))  $HAL_PROP_LINUX_ACPI_PATH

Does this work on your laptop.  Could you also please include the DMI
decode data for your laptop as detailed on the HotkeyResearch page above
so that we can identify your laptop.

** Changed in: gnome-power-manager (Ubuntu)
Sourcepackagename: gnome-power-manager = hal
