Hi! I have since installing 18.04 not been able to set timout for blank screen. After 10 minutes inactivity the screen goes blank whatever settings I have chosen. It's really enoyung vwhilst I'm watching a movie or such. Even using VLC it goes blank. Only SMPlayer overrides whichever devilish settings is activated without my knowledge. Been searching the net for answers but find nothing to solve this problem, please help!
I use VLC often to watch videos through HDMI. No issue with the sceen going blank as long as a video is playing. But if not, not only does the screen go black, the HDMI sound setting changes.
Well, VLC is not my main problem, it's when I'm streaming and therefor "inactive".
