I have just installed ubuntu 11.10 oneiric on my dell studio 1569. I am experiencing a strange problem with brightness control, volume control etc: my hotkeys are enabled and, apparently, when I use them the indicator of volume and brightness changes. Same result when i manually change brightness and volume. But to the change in the indicator does not correspond any change in the effective brightness and volume. Any idea about what can I do?

thanks a lot, /matteo

Excerpt from the answer at ubuntugeek.com

  • Install Brightness indicator on ubuntu
  • Download deb package from here and install by double clicking on it.
  • After installing the package, add the program to your startup programs:

    • Run System Settings » Startup Applications » ‘Add’
    • Name: indicator-brightness

      Command: /opt/indicator-brightness/indicator-brightness.py

      Comment: optional

    • Click ‘Add’.

I found the solution to a similar problem this way:

Add the next option under your "Device" section in /etc/X11/xorg.conf and restart:

Option "RegistryDwords" "EnableBrightnessControl=1"

This worked for my NVIDIA card.
