now i just have to make a widget or something that does

----------------
"get value" from widget (brightness)
echo (brightness) >/sys/class/backlight/acx565akm/brightness
write/echo (brightness) >/home/user/bright_setting

than it should change brightness and use the value from /home/user/bright_setting

the widget can be made with 2 - xx memory settings for the settings you like to use.

MANY thanks to JonWW for all the help in finally making this work.
No more stupid ALS and a custom brightness thats suits the user

I have made a complete guide to this at the first post now.

This so far only gives you 1 brightness setting but a homemade widget can be made to give you more settings.
This does not change the stock 5 settings, witch after the removal of ALS will be 5 very low steps.
If anybody finds out how to change the 5 stock steps to 5 custom steps please post it here or let me know .
