Document Viewer or Evince is the default PDF reader application on Ubuntu. It originates from GNOME and its real name is evince. As its name suggests, Document Viewer's purpose is to display various digital documents and electronic books, like PDF and other formats. It has many features: simple, easy to use, presentation mode, and a lot more. We will explain in detail what is and how to use it on Ubuntu 24.04 "Noble Numbat" in the rest of this article. Now, let's start reading!

Disks, or GNOME Disk Utility, is the Ubuntu default disk storage management application. Its purpose is to manage everything about hard disk drives and other storage on your Ubuntu computer -- including optical discs (CDs, DVDs) and USB flash drives. That means you can alter the filesystem inside that disk (create, remove, resize, and rename it), format the disk (to MBR or GPT), make a backup, as well as write an ISO image to that disk, and do other useful things such as benchmarks and more configurations.

In this episode, we will remind you The List of Ubuntu Default Apps, Adjusting Cursor Size, as well as Thunderbird Setup, each with a brief description. We hope this compilation series will be useful to you and everyone. This marks our last article of that year in June. Please enjoy!

This tutorial is inspired by errors and fixes we encountered when testing openSUSE Leap 16 yesterday. The problem is a kernel panic at boot time, so we cannot run it the same way we usually run other GNU/Linux operating systems up to today. After looking up and re-reading our old articles, we found out a solution. We hope you can run Leap 16 on a virtual machine quickly and easily with this. Now let's start reading and practicing!
