TO DISABLE ALS:


in /etc/mce/mce.ini

under [Modules] > list of modules to load,
change "filter-brightness-als" to "filter-brightness-simple"

then reboot.

You need to be root to do it, I edit files as root through SSH over Wifi using WinSCP on my PC. The latest version of SSH for N9 disables SSH root access, I had fun re-enabling it. See here: http://talk.maemo.org/showthread.php?t=79645


Or you can use Nano:

1. open xterm
2. devel-su [enter] then your root password [enter]
3. nano /etc/mce/mce.ini

then use the arrowkeys on the virtualkeyboard to navigate the file, and make the change.

once done, ctrl+o then enter saves the file
ctrl+x closes Nano
