We live in a world that wants us all to be environmentally aware and ask us to use less power with our electronics and to save as much power as we can. For years operating systems have had to build in options to provide for power management. On laptops this can be a good thing as it allows us to control just how much battery is being used and how quickly it will be drained. The problem is of course on desktop systems or when the laptop is plugged in.
One of the most annoying aspects of power management is when the computer decides to power down the monitor you are suing. Depending on your settings this can happen a lot and can be annoying. This is easy to stop from happening on most Operating Systems and luckily it can be stopped on Ubuntu too.
Stopping the Monitor from Powering Off
The first thing you will need to do is to find where the Power Management Preferences are. To find these settings navigate to system, then preferences then to power management. Once this has been selected you will then find a tab for “Running on AC” which is of course meaning when the computer is either a desktop or a laptop that is plugged in.
From here you will see options for Sleep, these will be two sliders that say “Put display to sleep when computer is inactive for” and “Put computer to sleep when it is inactive for”. Simply slide these sliders so that it now says “Never” underneath. You can of course change these to any values you want, but as this How-to is telling you to stop any going to sleep operations that is what I’m describing.
Once you have done this you should then find that the screen and the computer itself will no longer go to “sleep” when it is left inactive for a certain amount of time. This saves us from the annoyance of having the screen go to sleep when we don’t want it to. It’s good to have power management such as this of course, but when we don’t need it it’s also good to be able to get rid of it.
