Switch back to Xorg on Ubuntu

Product: Synergy (all versions)
Operating system: Linux

Wayland support is here

Synergy 1 and Synergy 3 now have experimental support for Wayland on Linux distros that have libei support.

Distros without libei support

There are two approaches for going back to Xorg if your Linux distro does not support libei (required for Synergy to work with Wayland).

You can also switch back to Xorg if you're having a problem with Wayland.

Use the login screen cog

To login with Xorg instead of Wayland on Ubuntu 21.04 an above:

1. Restart computer
2. Select the small cog on the bottom right corner at the login screen.
3. Choose 'Ubuntu on Xorg' and login

Using Ubuntu on Xorg

Edit the GDM config file

Sometimes the login screen cog is not visible. The alternative is to edit a config file.

To do this, edit the file /etc/gdm3/custom.conf with any text editor, and un-comment the line that reads 'WaylandEnable=false‍'.

For example, using gedit:

1. Run the Terminal app, and enter the command:

sudo gedit /etc/gdm3/custom.conf

2. Un-comment the line to disable Wayland by removing the # sign:

WaylandEnable=false

3. Finally, restart GDM:

sudo systemctl restart gdm3

Troubleshooting

The gedit command doesn't exist

You may be running a Linux distro that doesn't have gedit. In which case you could use something like nano instead.

Yellow screen problem

If you see a yellow screen after disabling Wayland, you may need to add the "Standard Space - sRGB" color profile (instead of your default monitor profile).‍‍

1. Go to Settings
2. Click Color
3. Click your monitor
4. Click Add profile
5. Click either Colorspace: sRGB or Standard Space - sRGB
6. Click Add

This should solve the yellow screen problem, if not please watch the video by Abstract programmer.
