Some of my applications don't work on Ubuntu 17.10 Wayland. How can I switch back to Xorg?
If you wish to do it permanently, edit
/etc/gdm3/custom.conf and uncomment the line:
by removing the
# in front of it.
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.
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
You can revert it easily if you change your mind with:
sudo dpkg-divert --rename --remove /usr/share/wayland-sessions/ubuntu.desktop
May be running app like this can help? Can someone try it? Because I don't know whether that will be helpful to others.
For example you need to run app called Putty from Wayland but it doesn't work because of font called "server:fixed" doesn't exist in Wayland, or may be it doesn't available for some reason. So you can change shortcut or run it from shell this way:
env GDK_BACKEND=x11 putty
Replace putty with something that you need.
You need to set varibale exactly with env
env GDK_BACKEND=x11, without env it will not work (for Putty at leased)
