Encountering the “Login Failed for Display: 0” error when using XRDP on Ubuntu 18.04.3 LTS can be a frustrating experience. However, there are several solutions to this issue. This article will guide you through the process of resolving this error, explaining each step in detail.
Understanding the Error
The “Login Failed for Display: 0” error typically occurs when there’s a compatibility issue between the XRDP server and the Xorg server. XRDP is a free and open-source remote desktop server that provides a graphical interface to remote users. Xorg, on the other hand, is the public, open-source implementation of the X Window System that provides the graphical environment.
Solution 1: Install the xorgxrdp-hwe-18.04 Package
The first solution involves installing the xorgxrdp-hwe-18.04 package. This package is designed to be compatible with the XRDP server. To install it, open the terminal and run the following command:
sudo apt-get install xorgxrdp-hwe-18.04The sudo command is used to run the following command with root privileges, apt-get is the package handling utility in Ubuntu, and install is the command to install the new package.
Solution 2: Downgrade the xorg-xserver-core Packages
If the first solution doesn’t work, you can try downgrading the xorg-xserver-core packages. To do this, run the following commands in the terminal:
sudo apt-get install xserver-xorg-core
sudo apt-get -y install xserver-xorg-input-allThe -y option is used to automatically answer yes to all prompts, which might be useful if you want to avoid answering any interactive questions.
Solution 3: Use Compiled Packages from Thiago
Another solution is to remove the existing XRDP package and install the compiled packages from Thiago. To do this, run the following commands:
sudo add-apt-repository ppa:martinx/xrdp-hwe-18.04
sudo apt-get update
sudo apt-get install xrdp xorgxrdpThe add-apt-repository command is used to add PPAs (Personal Package Archives) to your source list. The update command is used to resynchronize the package index files from their sources.
Solution 4: Use the Installation Scripts
The final solution is to remove the existing XRDP package and automate the XRDP installation using the provided installation scripts. There are two options available:
- To use Ubuntu repository packages, follow the instructions and download the script from this blog page.
- To compile from source, follow the instructions and download the script from this blog page.
Final Checks
After trying the above solutions, ensure that you have set a different username and password for XRDP than the one you are using to connect. Avoid using usernames that start with a number or capital letter, as these can cause login issues. If you are using GNOME as your desktop environment, be aware that there may be known issues. Consider trying a different desktop environment if problems persist.
