I just installed Ubuntu Studio 19 and I've adjusted my power management settings to NEVER switch off or go to sleep but it still blanks my screen. I double checked my monitor and it's not doing it by itself. I've rebooted the system but it's still doing it.
It's irritating to have to keep moving the mouse so I can watch video.
Please advise.
