This code will only ever activate when the brightness changes (hopefully), I have not been playing around with /etc/mce/mce.ini so cannot say how well it will work for you.
Can you tell me how to make your nice script run on boot.

as i said i'm not the most hardcore programmer, so if anybody can tell me how to get JonWW's script to start up on boot that would be nice.

You could try with fcron, but tread carefully:

Re: Custom Brightness for N900 - no ALS
 
Look in
Code:
/etc/event.d
the start up scripts for many programs are in there, look at them and adapt one to suit your needs.

Re: Custom Brightness for N900 - no ALS
 
allmost got it working now just need help with one last thing:
It now starts the scrips on boot (started hildon-desktop) but it does not keep running, and brightness is back to normal after keyock or "fadeout"

my /etc/event.d/frost_custom_settings
--------------------------------------------------
start on started hildon-desktop
stop on starting shutdown

script
echo 4 >/sys/class/i2c-adapter/i2c-2/2-0063/region
cat /home/user/bright_setting >/sys/class/backlight/acx565akm/brightness
dbus-monitor --system type='signal',interface='com.nokia.mce.signal',mem ber='display_status_in' | while grep -q "display_status_ind"
do
cat /home/user/bright_setting >/sys/class/backlight/acx565akm/brightness
done
end script
-----------------------------------------

what am i doing wrong???

Re: Custom Brightness for N900 - no ALS
 
Run an boot setup should go here
/etc/event.d/frost_custom_settings:
Code:
start on started hildon-desktop
stop on starting shutdown
exec /etc/init.d/frost_custom_settings
Appartently scripts to then be run should go in /etc/init.d so
/etc/init.d/frost_custom_settings:
Code:
echo 4 >/sys/class/i2c-adapter/i2c-2/2-0063/region
cat /home/user/bright_setting >/sys/class/backlight/acx565akm/brightness
dbus-monitor --system type='signal',interface='com.nokia.mce.signal',member='display_status_in' | while grep -q "display_status_ind"
do
  cat /home/user/bright_setting >/sys/class/backlight/acx565akm/brightness
done

Re: Custom Brightness for N900 - no ALS
 
still no cigar.....
it still only runs on startup, but doesn't keep going....


scratch that, there was a typo in the code in my script.....
member='display_status_in' should had been member='display_status_ind'

Re: Custom Brightness for N900 - no ALS
 
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 :).

Re: Custom Brightness for N900 - no ALS
 
Try experimenting with 'Simple Brightness Applet' in your do loop to see what value it set the screen brightness to, then if those value appear when you 'cat /sys/class/backlight/acx565akm/brightness' substitute you own values to suit you.

Run you script in XTerm to see whats going on first.

Keep us updated.
