In Scribus, when we use Text Frame, it will choose one font by default. Sometimes, we need to change this default font. To do it, go to menu File > Preferences > Tools > Text Frame Properties > change the default font. In this example, we choose FreeSans Medium 12pt. So, every new frame in new document will have this font.

When user writes long document such as book, it is easier if they can change whole headings' fonts by few clicks only. Actually, some important parts in LibreOffice Writer document such as default font, heading, list, caption, and index have their own setting. So it is possible to change just one or whole types. To change default font in Writer, open menu Tools > Options > LibreOffice Writer > Basic Fonts (Western) > choose what type font you need to change. See picture below.

When a computer crashes, our work with Scribus may be corrupted. Things get worse when user didn't enable autosave. If so, all works when crash happens will be lost. So it is better to enable autosave in Scribus. Go to File > Preferences > Document > check Autosave > set interval time. Smaller value means safer.

Every new user will experience dealing with package dependency in Ubuntu. This list is a shortcut to help you get what dependencies you want in faster way. You can choose any command you need from below. We list variety of 5 commands here dpkg, dpkg-deb, apt-rdepends, apt-cache, and apt-get. We use Ubuntu 12.04 32 bit for this article. If you are looking for package dependency searching in Ubuntu then this article is for you.

To enable autosave in LibreOffice, go to menu Tools > Options > Load/Save > General > check Save AutoRecovery information every option > give a time value. For example, we give it 1 minute so LibreOffice will do autosave every 1 minute. You can also check Always create backup copy option so LibreOffice will always save hidden file as a copy of your current document. That kind of file is very useful after the computer experienced power failure or any other disaster. See picture below.

apt-rdepends is a great tool to list complete dependencies of a package. Beside of that, apt-rdepends has capability to produce graph-compatible output. In other words, user can use apt-rdepends to produce dependencies list then use dot to create dependencies map in an image file (whether it is PNG or else). In this article, we will create maps for some Ubuntu packages separately.

Scribus 1.5 NG has released both in upstream (developer source code) and in downstream (i.e. PPA repository). Scribus 1.5 for Ubuntu is available for 14.04, 15.04, 15.10, and 16.04. Notice that it doesn't provide 14.10. Although 1.5 is a testing version (a preview for the next 1.6 release), probably you want to test the new features or its stability on an experiment environment (i.e. live session). This guide needs you to open Terminal (Ctrl+Alt+T) and perform three commands. You will need internet connection to do it.

Usually we  can add a new PPA repository by adding it into Software Sources (software-properties-gtk) either from Ubuntu Software Center or Synaptic. But actually we can add same PPA manually. This manual method will help user to easily remove unused PPA later.

Those who use Ubuntu in internet-restricted area such as college or office, probably will need proxy configuration for their apt-get command. Especially in the college, when every student given username and password for campus proxy to connect to the internet. Actually we just need to configure proxy or with/without authentication in apt.conf file. Here we go.

We've written a guide about Synaptic previously. Now we need to write about GDebi. GDebi is a package manager to install a single .deb package in Ubuntu. GDebi will help you resolve dependencies automatically by right-clicking on the package file. We will give two different examples to use GDebi here.

At the old days, Ubuntu brought Synaptic Package Manager in every release until it completely replaced with Ubuntu Software Center at 11.10 Oneiric Ocelot. Synaptic and Ubuntu Software Center are basically same things (package managers) but different in features. Ubuntu Software Center (later called as USC) is easy to use for beginners. But for many reasons, somebody will need Synaptic again. For example, Synaptic has advanced settings and detailed information in every action it does (while USC hides almost all detailed information). So here is a guide to use Synaptic.

Add/remove program system is the core functionality in every operating system. In Ubuntu nowadays, this functionality is handled by Ubuntu Software Center (will mentioned as USC). This is a beginner guide about using USC, introducing you basically how to do add/remove program in Ubuntu. USC resembles Google Play Store for Android user or App Store for Apple OS X and iOS user. Enjoy.

Previously, we've written a customization guide for LXDE. Now we write about KDE customization. KDE is the most complex desktop environment among which we've written about here. But don't worry it is a basic guide to customize KDE starting from changing wallpaper until installing new theme. We use KDE 4.8.5 on Kubuntu 12.04 as a basis. We hope it helps everyone begins KDE. Enjoy.

We have just written about XFCE tweaking yesterday. Now we need to explain briefly how to tweak LXDE. LXDE is different because it makes use of Openbox as window manager. Customizing LXDE is customizing Openbox too. Fortunately, LXDE can make use of GTK and Openbox themes available everywhere. We use Lubuntu 14.04 to demonstrate this guide. We hope this basic guide may help anyone uses LXDE. Enjoy.

Our latest desktop customization guide was Cinnamon. Now, we're moving into XFCE. This guide can be applied to customize Xubuntu, Manjaro XFCE, openSUSE XFCE Spin, or any Linux distro using XFCE as the desktop. We cover how to install desktop theme, add new panel, add applet, and we start them from concepts. Enjoy.
