On Ubuntu, where is the config file?

[sunilwu]

I've set up Synergy on my network. 
The host machine uses Ubuntu 18.04.

I can't find the config file.
There is no config file under ~/.synergy.

I'd like to try and see if I can do keymapping: One of the client machines is a Mac, and the keymaps in the Screen Settings don't work.

So, where exactly is the config file?

Thanks.

The config file is generated each time the program starts in /tmp. If you want a physical file you will need to tell synergy to save the file then set it to load form the file you just saved

[File]->[Save Configuration file]

The select [Use existing Configuration] and locate the file you just saved.
