Sound and Brightness Control not working on fresh install
I recently installed a fresh copy of Intrepid Ibex on my HP laptop. I previously had Jaunty Jackalope and decided to downgrade to what would hopefully be a less buggy version of ubuntu. Since the fresh install neither the sound nor the brightness can be adjusted! There's no sound at all and brightness is stuck at 100%. The fn key sliders are functioning, but nothing happens. I've already tried adjusting both settings manually under system>preferences, and I have deleted PulseAudio with no results. Please help! Should I just reinstall the OP? this bright screen is an eyesore!
thanks in advance for your help
