How to Install X2go on Elementary OS

X2go is a server-based computing environment that allows users to access applications and desktop environments remotely. In this tutorial, we will walk you through the process of installing X2go on Elementary OS Latest.

Step 1: Add X2go Repository

Open the terminal by pressing Ctrl + Alt + T.
Run the following command to add X2go repository to your system:
```
sudo add-apt-repository ppa:x2go/stable
```
Press Enter when prompted to continue.
Update your system by running the following command:
```
sudo apt-get update
```

Step 2: Install X2go Packages

Run the following command to install X2go server and client packages:
```
sudo apt-get install x2goserver x2goserver-xsession x2goclient
```
Hit Enter when prompted.

Step 3: Configure X2go Server

Open the terminal and run the following command to edit the X2go server configuration file:
```
sudo nano /etc/x2go/x2goserver.conf
```

Find the following lines in the file:

# session limits
# Maximum number of parallel sessions (per user account) that are allowed
# Default: 2
SessionLimit=2

Change the value of SessionLimit to the desired number of simultaneous sessions. For example, if you want to allow three sessions, change the value to:
```
SessionLimit=3
```
Save the changes by pressing Ctrl + X, then Y, and then Enter.

Step 4: Start X2go Server

Run the following command to start the X2go server:
```
sudo systemctl start x2goserver.service
```

Verify that the X2go server is running without any errors by running:

sudo systemctl status x2goserver.service

If everything is running fine, you should see the following:
