Hi Al et al. I started with that page as well as looking through the web. Today I did a reset of my MAC OS X's PRAM and VRAM. Now the brightness at start is fine again but I can't change it. Both Light related Keyboard Functions aren't working. Means: - F1 and F2 (can be used to adjust display brightness) - F5 and F6 (can be used to adjust keyboard backlight bright) The rest (F7-F12 for Audio) works fine! I already reinstalled pommed and the Nvidia driver. No change after restart of Xserver or the system as whole. Already updated the system again with no effect. It's odd because everything ran out of the box after the 1st installation weeks ago...

It's for 10.10 but some of the tips are probably safe on 10.04 too. Cheers, Al. </blockquote>
