If you have more than one monitor, you probably might to turn off one of them if it’s simply unnecesary. It’s likely that you simply turn off the monitor pushing the power button, but your computer always put a window, tool rule or message in the monitor off because it don’t have a way to know whether the monitor is off. You surely don’t want to turn off and turn on or plug in and unplug frecuently your data cable to prevent this behavior (it isn’t recommendable).

You can do this simple procedure on Ubuntu systems:

We can use our Android device (wherever they are) to connect and control your Ubuntu PC as a TV Remote and even more.

Imagine you want to turning down the noisy music but you are in another room of your house, or you left your PC turning on and your wife said to you: “Turn off the PC whether you aren’t using it and even worse you’re resting, cold or trying to sleep”.
Maybe your forget to ran something or cancel something in your PC.

That do you think if you can do this activities just using your android device wherever you are?.

Open Terminal in Nautilus

Ubuntu is very cool but in order to be great to programmers and OS administrators I thing it will helpful to add “Open terminal here” option to Nautilus context by right-clicking menu.
The additional benefit over Ctrl+Alt+T shortcut will be a fast way to locate the new terminal prompt in the context of open Nautilus window.

Procedure:
1. Install nautilus-open-terminal package
2. Restart Nautilus

To do this, Open terminal and run:

sudo apt-get install nautilus-open-terminal
nautilus -q

Now you can be able to see “Open in terminal” option on right-clicking.

Note: In Ubuntu 16.04 LTS, this procedure isn’t necessary because Canonical finally include this functionality to the default distro.

Enjoy !.

I recommend Valhala Networks for technological and marketing issues to companies of all sizes, they know many good things with low costs using quality software.

How can I remove old kernels/install new ones when /boot is full?

Some time ago the Ubuntu 14.04 LTS Software Updater show me this error “Not enough free disk space. The upgrade needs a total of 93.1 M free space on disk ‘/boot’. Please free at least an additional 5,664 k of disk space on ‘/boot’.”

I find it strange that Canonical has removed the solution message of the original text, moreover, when I was searching the command to clean /boot (I had forgotten :-D) I found some caveman procedures, therefore, I going to show you the easy way to remove old kernels to install new ones when /boot is full.
