So, I am a bit perplexed and I cannot seem to solve the problem, but gnomes screen inactivity does work. No matter what I set it to, after x amount of time the screen never blanks, and turn off my monitor. I've tried with a brand new user on my system and the same problem with the user.
If it matters at all, I switched my login to lightdm, but this did work on a previous build. Any thoughts on troubleshooting and debugging the problem?
