Synergy works on Ubuntu 21.04 and 22.04 LTS, however it requires you to switch to Xorg and disable Wayland.
This is a little bit easier in Ubuntu 21, but is more difficult in Ubuntu 22.
To login with Xorg instead of Wayland on Ubuntu 21:
1. Restart computer
2. Select the small cog on the bottom right corner at the login screen.
3. Choose 'Ubuntu on Xorg' and login
In Ubuntu 22, the login settings menu was removed, so the only way to switch back to Xorg (and disable Wayland) is to edit the config file. To do this, edit the file /etc/gdm3/custom.conf with any text editor, and uncomment the line with 'WaylandEnable'.
For example, using gedit:
1. Run the Terminal app, and enter the command:
-code- sudo gedit /etc/gdm3/custom.conf -/code-
2. Uncomment the line to disable Wayland by removing the # sign:
3. Finally, restart GDM:
-code- sudo systemctl restart gdm3 -/code-
If you have any problems, read the article on linuxconfig.org.
You may be running a flavor of Linux that doesn't have gedit. In which case you could use something like nano instead.
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.
