How to Switch to Xorg from Wayland in Ubuntu 17.10 [Quick Tip]


Most of you probably are not aware of this, but in Ubuntu 17.10, the default display server used was switched to Wayland (the default display server used in Gnome Desktop) instead of the usual Xorg. In most cases this is a good thing, as Wayland is more secure and fixed a lot of shortcomings found in X11. The bad thing is it will break some apps that still depend on the old X11 server.

Luckily, Ubuntu comes with both Wayland and Xorg installed, and you can easily switch between both. Here we’ll look at how you can switch to Xorg from Wayland in Ubuntu 17.10.

Switch from Wayland to Xorg in Ubuntu

By default, when you log in to your Ubuntu desktop, it will run Wayland. To switch to Xorg you will have to log out of your current session.

1. At the login screen click on the cog icon beside the “Sign In” button.


2. Select the option “Ubuntu on Xorg.”


3. Enter your password and log in to your Ubuntu machine.

That’s it. Your Ubuntu is now running on Xorg, and your old apps should work now. Do note that this will become the new default every time you log in, until you revert back in the login screen.

How to Check if you are running Xorg or Wayland

If you just want to find out which display server your Ubuntu is currently running, you can use the following command to do so:


If you see X11, then you are running Xorg. Similarly, if you see “wayland,” then you are running Wayland.


What do I do if I don’t want to switch back to Xorg?

There will be some apps that require root permission that won’t run in Wayland. For example, if you are still using the old handy Synaptic app, it won’t run in Wayland. You will probably see an error like the following image.


If you just need to run one app and have no wish to switch back to Xorg because of this, here is a fix to run that app in Wayland.

In the terminal type the following command:

xhost +si:localuser:root


What this command does is add the local user (or current user) to the list of allowed connections to the X server. After that you will be able to launch your apps with sudo.


When Canonical decided to switch back to using Gnome desktop for Ubuntu, they also decided to embrace all the stuff that comes with Gnome, including Wayland. It is a good choice, though, and if you ever need to switch back to Xorg, you now know how to do that.
