Lesson 1

In this course you will learn how to configure key Linux components, and you will troubleshoot common and uncommon problems.

System-wide locale settings are stored in the /etc/locale.conf file, which is read at early boot by the systemd daemon.The locale settings configured in /etc/locale.conf are inherited by every service or user, unless individual programs or individual users override them. The basic file format of /etc/locale.conf is a newline-separated list of variable assignments. For example, German locale with English messages in /etc/locale.conf looks as follows:

LANG =de_DE.UTF-8
LC_MESSAGES =C

Here, the LC_MESSAGES option determines the locale used for diagnostic messages written to the standard error output. To further specify locale settings in /etc/locale.conf, you can use several other options.
Options configurable in /etc/locale.conf
See the locale(7) manual page for detailed information on these options. Note that the LC_ALL option, which represents all possible options, should not be configured in

/etc/locale.conf

While Red Hat does offer an enterprise-grade Linux distribution called Red Hat Enterprise Linux (RHEL), it is not typically used for desktops and can be expensive. If you're looking for a Red Hat-based Linux distribution for your desktop that is free and designed for daily use, consider these options:

• Fedora Workstation: This is the official Red Hat-sponsored community distribution. It's known for being up-to-date with the latest software and features, making it a good choice for users who want a modern and cutting-edge experience.
• CentOS Stream: This is a rolling-release distribution that provides a preview of what will be included in future versions of RHEL. It's a good option for users who want a stable and reliable system with access to newer software.

Both Fedora and CentOS Stream offer user-friendly desktop environments (like GNOME) and can handle the tasks you'd typically perform on Windows 11, such as web browsing, office productivity, multimedia consumption, and even some gaming.

• Other Red Hat-based options:
• Rocky Linux and AlmaLinux: These are community-created distributions designed to be 1:1 replacements for RHEL, making them stable and reliable options if you're familiar with RHEL.

It's recommended to try out a few different distributions to see which one best suits your needs and preferences. You can create bootable USB drives or use virtual machines to test them without making changes to your current system.

The changes in the desktop area for the next version of Red Hat Linux involve three major pieces:

1. Develop a set of artwork in-house to use for the desktops as well as for other pieces of the distribution. This set of artwork, the Bluecurve look, includes, among other things, desktop backgrounds, widget themes, window border themes, and icons.
2. We have configured the default settings and application shortcuts for both desktops in a similar fashion.
3. In a few places where we feel that there are significant advantages to sharing underlying technology between the desktops, we have made code modifications to use this technology. An examples of this is modifying both desktops to use Xft2 and fontconfig for font rendering.
