Command line control of N900 screen brightness?
 
Can the N900's screen brightness be set via the command line?

Alternatively, does some application like Simple Brightness App have a command line interface that can be used to set screen brightness?

Code:
gconftool-2 -s /system/osso/dsm/display/display_brightness -t int 5
Change 5 to the brightness level you want.

Code:
#!/bin/sh

gconftool-2 -s /system/osso/dsm/display/display_brightness -t int $1
Shove that into some script (/usr/bin/set_brightness) and use set_brightness 1/2/3/4/5 (chmod +x /usr/bin/set_brightness first)

Nice. Why the brightness value needs to stick to 5 levels?
Is there a method to make it 10 to 50 for example?

Thank you.

Is there a similar command to turn the screen saver off?

It would be useful to put in a script for calling X11 VNC Server, so that the screen doesn't go black.

gconftool -s --type int /system/osso/dsm/display/inhibit_blank_mode X

With X:
0 -- dont inhibit blanking (means screensaver on)
1 -- Inhibit dimming/blanking while charging

(undocumented, use with caution)
2 -- Allow dimming, but inhibit blanking if charger is connected
3 -- Inhibit dimming/blanking
4 -- Allow dimming, but inhibit blanking

I need help. Suddenly my screen has become permanently bright. Reducing the brightness level in settings does not help; and it is still bright when the back light times out. It doesn't make my battery last. Have to recharge every four hours!!!

Thanks

You can check if the light sensor works with this command:
Code:
cat /sys/bus/i2c/drivers/tsl2563/2-0029/lux
when you cover the sensor it should give 0 and in light, the lux of the light. I got 8177 by shinning a flashlight on it, and 5 in poorly lighted room.
