I am trying to get ubuntu 16.04 working with a geforce gt 640. Now i am trying to have 6 clients of the eve client running, had two running and i had an issue of being able to only interact with one reliably. The x server setting is not saving changes for the three monitors i am trying to use. How do i get reliable mouse pointer use across the clients? Is there programming i need or is there a setting i am missing somewhere?
