Ubuntu: How do you switch from Wayland back to Xorg in Ubuntu 17.10?



Question:

Some of my applications don't work on Ubuntu 17.10 Wayland. How can I switch back to Xorg?


Solution:1

When you boot your system and get to the GDM login screen you should find a cogwheel (⚙️) next to the sign in button. If you click on the cogwheel you should find an Ubuntu on Xorg option which will start an Xorg session instead of a Wayland session.

enter image description here


Solution:2

If you wish to do it permanently, edit

/etc/gdm3/custom.conf and uncomment the line

#WaylandEnable=false by removing the # in front.

Save the file and then on reboot you will never see the cog asking for which session to use.

EDIT

Apparently @doug beat me to this answer. I didn't see it earlier - It was in a comment that was hidden initially


Solution:3

You may want to remove wayland session to prevent accidental logins.

Your package maintainers will be proud of you if you do it as follows:

sudo mkdir /usr/share/wayland-sessions/hidden  sudo dpkg-divert --rename \        --divert /usr/share/wayland-sessions/hidden/ubuntu.desktop \        --add /usr/share/wayland-sessions/ubuntu.desktop  

What this does is to instruct the package manager to remember a new location for the file. This has several advantages over the other answers:

  • It guarantees a future package install/upgrade won't revert your change
  • It works with other display managers (lxdm for example lists .backup entries)
  • You can revert it easily if you change your mind with:

    sudo dpkg-divert --rename --remove /usr/share/wayland-sessions/ubuntu.desktop
