With this indicator you can set your screen brightness in Ubuntu Unity.
Features:
- Clicking the icon shows you all the possible brightness values, to a maximum of 15 steps.
- The current value is indicated with a dot.
- Clicking a menu item sets the brightness to the desired value.
- Scroll wheel event is enabled on the icon. Scrolling up means higher brightness, scrolling down lower.

Is this safe for use on xubunt?
Posted 06 Sep 2011 at 05:47 ¶@gorojaa: This won’t work on Xubuntu, as it is based on XFCE which uses its own applets. This is only for Unity.
On XFCE you can use a plugin that can show Gnome applets, and then use Gnome brightness applet.

Indicator throws error in Ubuntu 11.10. Not working.
Posted 07 Oct 2011 at 20:40 ¶@vivek: What exactly is the output when running /opt/indicator-brightness/indicator-brightness.py from the command line?
Posted 08 Oct 2011 at 12:56 ¶works perfect with oneiric for me! thanks!
Posted 10 Oct 2011 at 15:05 ¶…although i had to chmod +x the py-file, this might be a bug
Posted 10 Oct 2011 at 15:06 ¶Same for me, I cannot get it to work on Oneiric
Posted 13 Oct 2011 at 21:53 ¶This is what I get when I interrupt it from running (because it gets stuck):
Traceback (most recent call last):

Any idea ? I do not know anything about this ‘main’ method
Posted 13 Oct 2011 at 22:02 ¶Okay so it worked for me my question is if I can add shortcuts to it to increase the brightness or decrease the brightness :S
Posted 22 Oct 2011 at 01:46 ¶Thanks a lot! It does work!
Posted 23 Oct 2011 at 18:42 ¶Hi, I’ve got everything working with this except The dropdown goes all the way from 1 up to 280! And the values don’t seem to be in order, i.e. 4 is brighter than 120.
Any idea where these parameters are being taken from?
Thanks for this work.

Posted 28 Oct 2011 at 18:26 ¶Very useful, works great on my System76 Gazelle, running 11.10! Might I suggest that you make the range go from 0 to whatever the max is instead of 1 to max? I already modified the version I downloaded but I thought that other people might also like the option to use the minimum screen brightness possible as well.
In case anyone is wondering what I did, just change lines 21 and 22 to
if curr_brightness == -1:
curr_brightness = 0
and line 56 to
Posted 05 Nov 2011 at 01:03 ¶for i in range(0, max_brightness + 1):
Ubuntu 11.10, 64-bit: works fine, thank you!
Posted 05 Nov 2011 at 16:40 ¶If you change the brightness value with the system settings-screen app, the new value is not recognized by your app! No refresh!
But otherwise it’s realy great stuff! [:-))
Posted 14 Nov 2011 at 20:15 ¶Hi,
you did made a good job!
but
How can i change the .py script to get brightness steps like 10,20,30…? and not 1,2,3…?
Posted 15 Nov 2011 at 07:15 ¶The list of 255 steps ist to long for me! ;-(
Thank’s!
best regards

Hi,
i’ve packed your indicator and uploaded it to a ppa: https://launchpad.net/~jan-simon/+archive/indicator-brightness
I also added a .desktop file so one can find it in the dash.
The natty-deb is untested (as i use oneiric) but should work as well.
Greeting, Jan
Posted 19 Nov 2011 at 03:30 ¶Great work Jan! Thanks! Will add it to my software sources.

Posted 06 Jan 2012 at 13:58 ¶Hi
What would be the command to increase/decrease brightness when using this program. I ask this so i can add hotkeys.
Regards
Posted 10 Jan 2012 at 02:10 ¶Dan
Great work… Thanx…
Posted 28 Jan 2012 at 18:42 ¶Nice. Can do with a few improvements though.
i.e.
for i in range(2, max_brightness + 1, int(round(max_brightness/20))):
so that gives you 20 brightness settings instead of 254 in my case.
start with 2 seems a lot better than 1 … because one is no backlight here. and that sucks (even finding the applet to turn it back on).
further improvements would be numbers from 1 to ten instead of the values, and less steps … but then you would need to take into account that the brightness levels should not increase linear.
Many thanks … for the script.
Posted 29 Jan 2012 at 17:48 ¶@Christian Stöveken: To get rid of the 254 steps, you can use the altered script that you can find in this post.
Posted 30 Jan 2012 at 08:52 ¶Thanks, working like a charm here in ubuntu 12.04 alpha
Posted 27 Feb 2012 at 18:33 ¶The installation went good, then I restarted, the indicator is in place but nothing happens when I change the values of the brightness. Ubuntu 11.10 x64 on Toshiba L-745-SP4142LC
Posted 04 Apr 2012 at 16:16 ¶@Jorge: The script executes gnome-power-backlight-helper which is (as far as I know) also used by Gnome/Unity to set the display brightness.
Posted 04 Apr 2012 at 16:20 ¶Does running “pkexec gnome-power-backlight-helper –set-brightness 0″ (or any sensible number) from the command line work for you?

I found the solution to my problem this way:
Add the next option under your “Device” section in /etc/X11/xorg.conf and restart:
Option “RegistryDwords” “EnableBrightnessControl=1″
This worked for my NVIDIA card.
Posted 04 Apr 2012 at 21:44 ¶Thanks a lot, very handy.

Maybe the ATI card is the culprit?

Just wanted to let you know, this works perfect on Precise!
Posted 15 Oct 2012 at 16:19 ¶WORKS in 12.10
Posted 01 Nov 2012 at 15:07 ¶Could you please update your fine indiciator script on your site with the version found here?
https://bugs.launchpad.net/indicator-brightness/+bug/1067911
It shows only levels starting from 1, removing the “zero turns off screen” bug.
Maybe it is of interest, because several sites link to you.
Posted 08 Jan 2013 at 14:59 ¶Hi, worked perfectly fine on 12.10 + Asus zenbook.
However there is a bug whe scrolling up, the brightness value can reah 0 or negavive, and screen is all black, no way to roll back if you moved the mouse !
I solved thos by changing line 25 :
if curr_brightness <= 0:
curr_brightness = 1
Excellent work thank you very much
Posted 18 Jan 2013 at 00:42 ¶Hi Poster, take a look at the new script to control the brightness with your keyboard.
