Usually, drivers for system devices are already supported in the kernel provided by Red{nbsp}Hat Enterprise{nbsp}Linux. However, occasionally, support for devices that have been released recently could be missing. In these cases, a driver update enabling your device may be available.
Devices necessary to complete the installation can have driver updates provided before the installation begins. If a device is missing a driver, but it is not essential during the installation, it is recommended to wait until after the installation completes, and install additional drivers afterwards. For instructions on installing and enabling additional drivers on the installed system using [application]*RPM* and [application]*DNF*, see the [citetitle]_{PRODUCT} System Administrator's Guide_, available at link:++https://docs.fedoraproject.org/++[].
Configure additional repositories
New software is installed from _package repositories_. Package repositories are organized sets of software and metadata that can be accessed by the [application]*DNF* package manager. By default, several update repositories provided by {PRODUCT} are configured automatically and you can install updates and additional software from those. However, if you want to set up additional repositories, for example ones containing your own software, some extra steps are needed.
For information about configuring additional software repositories, see the [citetitle]_{PRODUCT} System Administrator's Guide_, available at link:++https://docs.fedoraproject.org/++[].
Install additional packages
You can control which packages will be installed by selecting an environment in the `Software Selection` dialog in the graphical installation (see xref:install/Installing_Using_Anaconda.adoc#sect-installation-gui-software-selection[Software Selection]). This dialog does not provide a way to choose individual packages, only predefined sets. However, you can use the [application]*DNF* package manager to install additional packages after the installation. See the [citetitle]_{PRODUCT} System Administrator's Guide_, available at link:++https://docs.fedoraproject.org/++[], for more information.
Switch to a graphical login
Depending on the options you chose during the installation process, it is possible that your system does not have a graphical interface, instead offering only a text-based prompt. If this is the case and you wish to enable a graphical desktop after the installation, you must install the [application]*X Window System* and your preferred desktop environment (either [application]*GNOME* or [application]*KDE*).
As with all other software, these packages can be installed using the [application]*DNF* package manager. For information about using [application]*DNF* to install new packages, see the [citetitle]_{PRODUCT} System Administrator's Guide_, available at link:++https://docs.fedoraproject.org/++[]. For information on how to enable graphical login by default, see xref:install/Troubleshooting.adoc#sect-trouble-after-graphical-login[Booting into a Graphical Environment].
