Introduction
Remote desktop access is essential for managing Linux servers and desktops without needing physical presence. Ubuntu, one of the most popular Linux distributions, offers multiple remote access solutions. Among these, XRDP stands out as a powerful, open-source implementation of the Microsoft Remote Desktop Protocol (RDP) server, enabling users to connect to Ubuntu machines via native RDP clients on Windows, macOS, or Linux.
This article focuses on Installing XRDP on Ubuntu, exploring what XRDP is, its benefits, installation and configuration steps, and best security practices to ensure safe and efficient remote desktop access.
What is XRDP?
XRDP is a remote desktop protocol server that allows users to graphically connect to a Linux machine from another computer using the RDP protocol. By supporting Microsoft’s RDP protocol, XRDP enables seamless remote desktop connections from Windows systems without requiring additional software.
Unlike other remote access protocols like VNC, which often require third-party clients, XRDP uses the standard Remote Desktop Connection client built into Windows, making it an ideal choice for cross-platform remote access to Ubuntu.
Why Choose XRDP on Ubuntu?
Ubuntu users opt for XRDP for several reasons:
- Native RDP Compatibility: XRDP uses Microsoft’s Remote Desktop Protocol, meaning Windows users can connect easily using their default Remote Desktop Client.
- Cross-Platform Support: Besides Windows, XRDP supports connections from macOS, Linux, and mobile devices with RDP clients.
- Resource Efficient: XRDP performs well even on lower bandwidth networks, providing a smoother graphical experience than some alternatives.
- Multi-Session Support: Multiple users can connect to separate sessions simultaneously, ideal for team environments.
- Open Source and Free: XRDP is fully open source, actively maintained, and free to use.
Prerequisites Before Installing XRDP on Ubuntu
Before proceeding with Installing XRDP on Ubuntu, ensure the following:
- You have Ubuntu installed (this guide assumes Ubuntu 20.04 LTS or later).
- You have a non-root user with sudo privileges.
- A working internet connection for downloading packages.
- Firewall access to allow RDP traffic on the default port 3389.
Step-by-Step Guide to Installing XRDP on Ubuntu
Step 1: Update Ubuntu System
Start by updating the system packages to ensure the latest versions are installed:
sudo apt update && sudo apt upgrade -y
Step 2: Install XRDP Package
Next, install XRDP from the Ubuntu repositories:
sudo apt install xrdp -y
After installation, the XRDP service automatically starts. Verify this by checking its status:
sudo systemctl status xrdp
You should see that the XRDP service is active and running.
Step 3: Install a Desktop Environment (If Not Installed)
Ubuntu Server installations typically don’t come with a graphical interface by default. If you’re running Ubuntu Desktop, you can skip this step. For servers, install a lightweight desktop environment like Xfce for better remote performance:
sudo apt install xfce4 xfce4-goodies -y
Step 4: Configure XRDP to Use Xfce
By default, XRDP uses the system’s default desktop environment, which might not be optimized for remote sessions. To configure XRDP to use Xfce, create or edit the .xsession
file in your home directory:
echo "startxfce4" > ~/.xsession
Set proper permissions:
chmod +x ~/.xsession
Step 5: Adjust XRDP Startup Configuration
Sometimes, XRDP may not start the correct session by default. To ensure it loads Xfce, edit the startup script:
sudo nano /etc/xrdp/startwm.sh
Find the last two lines:
. /etc/X11/Xsession
Replace or add before it:
startxfce4
Save and exit.
Step 6: Allow RDP Port in the Firewall
If you are using UFW (Uncomplicated Firewall), allow the default RDP port 3389:
sudo ufw allow 3389/tcp
sudo ufw reload
Step 7: Restart XRDP Service
Apply all changes by restarting the XRDP service:
sudo systemctl restart xrdp
Connecting to Ubuntu Using XRDP
Once XRDP is installed and configured, you can connect from a remote machine.
- Open Remote Desktop Connection on your Windows machine (search “mstsc”).
- Enter the IP address or hostname of your Ubuntu machine.
- Enter your Ubuntu username and password at the XRDP login screen.
- You will be connected to your Ubuntu desktop environment remotely.
Securing XRDP on Ubuntu
Security is critical when enabling remote access. Here are important security tips to keep XRDP on Ubuntu safe:
1. Use Strong User Passwords
Ensure that all user accounts have strong, unique passwords to prevent unauthorized access.
2. Limit Access with Firewall Rules
Restrict which IP addresses can connect to port 3389 via firewall rules.
3. Enable TLS Encryption in XRDP
XRDP supports TLS encryption, which you can enable by configuring certificates in /etc/xrdp/
and modifying the xrdp.ini
file.
4. Use SSH Tunneling for XRDP
Rather than exposing port 3389 directly to the internet, create an SSH tunnel to encrypt the RDP traffic.
5. Monitor XRDP Logs
Regularly review XRDP logs located in /var/log/xrdp.log
and /var/log/xrdp-sesman.log
for any suspicious activity.
Troubleshooting Common XRDP Issues on Ubuntu
Black Screen After Login
This usually happens when the desktop environment is misconfigured. Make sure .xsession
contains the correct command startxfce4
, and the desktop environment is installed properly.
Unable to Connect to XRDP Server
Check if the XRDP service is running:
sudo systemctl status xrdp
Ensure the firewall allows traffic on port 3389, and the server’s IP address is correct.
XRDP Connection Drops Unexpectedly
This can be due to resource limitations or network instability. Try switching to a lightweight desktop environment like Xfce and checking system resources.
