The only trick I've found is : xgamma -gamma 0.5 and that works. Hot keys Fn 6 and Fn 7 are active but have no effect on the brightness of the LCD. WORKAROUND: I have fixed my problem by installing nvidia-current (through Synaptics package manager) which was not installed. After installation I had to add this line in the Device section of xorg.conf : on "RegistryDwords" "EnableBrightnessControl=1" --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.21.
