The brightness keys in my vostro 1000 and Ubuntu 7.10 are completely
dead. Before upgrading they keys behaviour was vey weird.
I still don't know where is the problem, and I don't have any solution.
I just can change the brightness manually using (*without* blacklisting
video module). At least is a temporary solution to me:
First, view all the possible levels in LCD brightness file:
choose one, say X level (for example 75), and
echo 75 | sudo dd of=/proc/acpi/video/VGA/LCD/brightness
Adding the option 'no_automatic_changes=0' doesn't works completely for
me. It just let me push the brightness down (Fn+UP doesn't works) and
only using a pure terminal (i.e. CTRL+ALT+F1).
The "brightness miniapplication" (I don't know the exact name in english) doesn't works. The gnome-power-manager doesn't shows me any option to adjust the brightness.
