I am trying to get
Symless Synergy version 1.8.8 to autostart when my Ubuntu 18.04 client desktop boots up. I have followed these instructions carefully, but
Synergy only starts after logging in.
I believe this is caused because
gdm3 is not loading on boot, but only after login. I used to have several display managers and was given an option of which one to load at the login screen. I got rid of the others and the option to load
gdm3 at login disappeared. I was hoping that because of this it was loading at boot. It doesn't appear so. I believe this could be a run level issue, but I am in uncharted territory here.
Can someone advise me on how to force
gdm3 to load at boot?
