## 9: Introduction
25+
!!! note

27-
The development team for Rocky Linux 9 has made installing XFCE, and other popular desktop environments, uncomplicated by including live images. For those that might not know what that is, a live image is a bootable image that will load the OS without installation. When loaded, you have the option to install it to your machine's disk drive and use it.
27+
Throughout this section, you will either need to be the root user or be able to `sudo` to elevate your privileges.

## 9: Get, verify, and write the XFCE live image
29+
When installing Rocky Linux, we used the following sets of packages:
3030

31-
Prior to installation, the first step is to download the live image and write that to a DVD or a USB thumb drive. As stated earlier, the image will be bootable, just like any other installation media for Linux. You can find the latest XFCE image in the download section for Rocky Linux 9 [live images](https://dl.rockylinux.org/pub/rocky/9.6/live/x86_64/). Note that this particular link assumes x86_64 is your processor's architecture.

As of this writing, you can use x86_64 or aarch64 architectures for this live image. Download the live image and checksum files.

Verify the image with the CHECKSUM file with the following

(note this is an example! Ensure your image name and CHECKSUM files match):
36+
First, run the server update command. The system will rebuild the repository cache. In this way, the system can recognize the packages available.

```

```

```

If all goes well, you will see this message:

## Enabling repositories
4443

45-
```
46-
Rocky-9-XFCE-x86_64-latest.iso: OK
47-
```
44+
You need the unofficial repository for XFCE in the EPEL repository, to run on Rocky 8.x versions.
4845

49-
If the checksum for the file returns OK, you are now ready to write your ISO image to your media. This procedure differs depending on the OS, the media, and the tools. We are assuming here that you know how to write the image to your media.
46+
Enable this repository by entering:

## 9: Booting

```
49+

This again is different by machine, BIOS, OS, and so on. You will need to ensure that your machine is set to boot to whatever your media is (DVD or USB) as the first boot device. This screen will show if you are successful:
52+
Answer 'Y' to install it.
5453

55-
![xfce_boot](images/xfce_boot.png)
54+
You also need the Powertools and lightdm repositories. Enable those now:
5655

57-
If so, you are on your way! If you want to test the media, you can enter that option first, or you can enter **S** to **Start Rocky Linux XFCE 9.0**.
56+
```
57+
dnf config-manager --set-enabled powertools
58+
dnf copr enable stenstorp/lightdm
59+
```

Remember, this is a live image. It is going to take some time to boot to the first screen. Do not panic, just wait! When the live image boots, you will see this screen:

## 9 minimal: Introduction
115+
You need to disable `gdm`, which gets added and enabled during *dnf groupinstall "xfce"*:
103116

104-
If you installed Rocky Linux 9.x and decide that you want to install XFCE after, this procedure will get you there. This procedure assumes installation of `Rocky-9.4-x86_64-minimal.iso`.
117+
```
118+
systemctl disable gdm
119+
```
105120

106-
### Update your system
121+
Now you can enable *lightdm*:

108-
First, ensure the update of your system:
123+
```
124+
systemctl enable lightdm
125+
```
109126

110-
```bash
111-
sudo dnf update -y && dnf upgrade -y
112-
```
127+
You need to tell the system after booting to use only the graphical user interface. Set the default target system to the GUI interface:

129+
```
130+

131+
```

116-
Secondly, run the command below to install epel-release repo which contains all packages that we need to install for Xfce Desktop.
133+
Then reboot:
117134

118-
```bash
119-
sudo dnf install epel-release -y
120-
```
135+
```

### Enable XFCE desktop on boot
143-
144-
At this point you have installed the XFCE desktop on the system and ensured it functions by running it from the command line. If you always want your system to start with XFCE instead of the command line, you need to run the following command. You will need to open the XFCE terminal from the 9 points icon first:
145-
146-
```bash
147-
sudo systemctl set-default graphical.target

XFCE is a light environment with a simplistic interface. It is an alternative to the default GNOME desktop on Rocky Linux. If you are running Rocky Linux 9, the developers have created a handy live image that speeds up the installation process.
