In this guide, we’ll explore the essential things to do after installing OpenSUSE.

In OpenSUSE, the following command is used to update the system:

sudo zypper ref && sudo zypper up


if you are running OpenSUSE Tumbleweed, make sure to run the following command to make sure that your distro version is up to date:

sudo zypper dup

Decrease Swapiness


Check the current swappiness value by executing:

cat /proc/sys/vm/swappiness # 60 (default)

Open /etc/sysctl.conf for editing:

sudo nano /etc/sysctl.conf

Add vm.swappiness=10 at the end and save the file. Then press CTRL + O to write the changes, and CTRL + X to exit nano.

Reboot your system and check the swappiness value:

cat /proc/sys/vm/swappiness # 10
