One of the things we have become accustomed to thanks to mobile devices is in set the brightness of our screen automatically to adapt it to the conditions in force at any given time; this is to increase the brightness when there is a lot of ambient light (for example at midday) and decrease it when night falls, something that on the other hand even has health connotations as it is proven that in the hours before sleep is not good for screens to ‘dismiss’ a lot of light.
The problem with all of this is that while laptops monitors and screens allow us to adjust the intensity of the screen light, Do not offer an automatic way to do this as with mobile devices (tablets and smartphones). But you can, rest assured you can, and in this post we’ll see how to adjust the screen brightness automatically in Ubuntu, Thanks to a tool called WildGuppy.
We can to install WildGuppy from the official PPA repository, Where we will find the version compatible with Ubuntu 12.04, 12.10, 13.04, 13.10 and 14.04 LTS. So, as we know the task is really very simple how to execute the following from a terminal (Ctrl + Alt + T):
its add-apt-repository ppa: fantasyleague0629 / wildguppy
sudo apt-get update
sudo apt-get install wildguppy
In case you are using Ubuntu 14.10 or higher we will have to download the .deb package and install it manually. In this case we can also open a terminal window, and run:
suo dpkg -i wildguppy_1.0.3-1_all.deb
Now we can start WildGuppy, And so we can start writing your name in the Unity Dash, or of course we can do so from the menu or launcher we use, in one of the many possibilities that GNU / Linux always offers. Once this is done we see that WildGuppy runs from the system prompt area, That is, the one in which we have the indicators of sound, battery charge and others.
This WildGuppy indicator is what will allow us control all screen brightness options, Which involves defining it manually or choosing to let the application take care of everything, which in the end is the idea (although we can still specify the interval from which s will update the settings, and the maximum and minimum brightness values).
However, such an application is more useful when we run it not only automatically but also by default, ie at each start of our computer. And that’s why we’re going to have to get our hands on it to create a file, which we need to place in the folder ./config/autostart from our personal directory. We can use our text editor of preference, in my case gedit:
~ / .Config / autostart / wildguppy-autostart.desktop
Then we add the following content to the file:
Type = Application
Exec = wildguppy-gtk
Hidden = false
NoDisplay = false
X-GNOME-Autostart-enabled = true
Name = WildGuppy
That’s it, and from now on every time we start our Ubuntu computer we will have WildGuppy by default, with all the benefits of being able to manage screen brightness automatically. And not to mention that above all things, we will be having much greater comfort.
