Reduce swappiness on Manjaro

 

Reduce swappiness

 Swappiness is to optimize the use of Swap and RAM. And it allows establishing the balance between both. By default when Manjaro uses a lot of the RAM memory it starts writing some files into the swap partition on your hard drive. The problem with this is the hard disk is slower than the RAM, so this makes the system slower. You can reduce the use of swap and use more RAM instead.

First, check the default swappiness value. Run in a terminal:

cat /proc/sys/vm/swappiness
Showing the default value of the Swappiness
Showing the default value of the Swappiness

The default value is 60, which is too conservative. I recommend changing the value to 10 if you have more than 4GB of RAM. To do this you need to create the file /etc/sysctl.d/100-manjaro.conf. Run this command:

sudo nano /etc/sysctl.d/100-manjaro.conf

In the file, you have to put the following:

vm.swappiness=10
Setting the value of the Swappiness on 10
Setting the value of the Swappiness on 10

Now, CTRL+O to save and CTRL+X to close the file.

In order for the changes to take effect, reboot the system.

Then, check the swappiness value again:

cat /proc/sys/vm/swappiness

And you’ll see it’s 10. So this way Manjaro will use your RAM memory more efficient.

Adjust Color Temperature of Your Screen Using Terminal

There is a utility called “ xsct ” or screen color temperature for Debian-based systems which is super lightweight to install and very easy to use. Open up a terminal and install it using below. sudo apt install sct Once installed, you can start using it anytime with just a command. Even you can use it for your shell script as well. Syntax sct [temperature]   What is Color Temperature As per Wikipedia – “ Color temperature is a characteristic of visible light that has important applications in lighting, photography, videography, publishing, manufacturing, astrophysics, horticulture, and other fields” . It has a value range from 1000k to 10000k (k = unit in Kelvin) which controls the display brightness. In layman’s term, the default color temperature value of your monitor is 6500k. So, anything upwards e.g. 7000k, etc are “blue-ish” or “cooler” and downwards are “warmer” or “yellow-ish”. Take a look at this chart (credit: Wikipedia).

  AirDrop & why it would be amazing for cross-platform Apple’s AirDrop is known to be one of the best data transfer services. It allows its users to quickly transfer files between devices while also providing a high level of security. However, it’s not available on any other platform, except for iOS and macOS. This means that if you want to transfer files and use AirDrop on Windows, you need to use SnapDrop. SnapDrop is a super-easy way to send files or data between your devices, and it works with anything, from PDF files to photos and videos. All you need to do is open it in your browser and then look for a device to exchange files with. It’s a great app, developed using some of the best security protocols. On top of that, it’s open-source, so developers are continuously improving it.
