I have a question first let me give some details. I am using Ubuntu Mate 18.04. I have an AMD GPU R7 260X using AMD drivers and I have three 24-inch monitors. My PC is a Dell XPS 8500 with 16 GB of RAM.
Here is my question, I use screensavers on my systems just for kicks. If I remember, I had to install the Xscreensavers. When my screensaver activates it displays a random screensaver on each of my monitors even though I have selected one screensaver to use (FireworkX for the time being) Not only do I get 3 different screensavers displaying simultaneously on my monitors but when I click the mouse to see my desktop, the desktop displays for a moment and then the FireworkX screensaver turns on, so I have to click the mouse again to see my desktop.
Does anyone have any ideas how I can correct this so my chosen screensaver displays on all three screens instead of getting three random screensavers?
