Hi Stefan, Sorry for de missing file. I forgot it since your request layed on the other thread of conversation. It's attached now.
The command had no effect than to change the "supposed" brightness level to 100%. I had tried it before, and it changes the /proc/acpi/video/GFX0/DD03 file as well as the Fn keys or the brightness applet in the pannel, but has no real effect ont the screen brightness. Hope you'll find the problem... > 2009/12/10 Stefan Bader <stefan.ba...@canonical.com> > Hi Pablo, still missing the acpidump output.
