Credit must go to you, too, y'know.....for sticking with us until we found the solution. We get no end of newbies who, at the first sign of a problem that needs a wee bit of work, disappear into cyberspace, never to be seen again.
But then you do have prior Linux experience, so you did at least know what to expect. For ex-Windoze users, sometimes it all just seems like too much hard work to sort out something that's often simple.....because it's not what they expect, or are used to.

@Mike Walsh, I don't mind spending time troubleshooting a problem. It’s so satisfying when I do find a solution, and I pick up a lot of useful information along the way. I spent many, many hours battling with this particular problem on my own before I finally threw in the towel and came to the experts for assistance.
Once again, my thanks to everyone who came to assist me.

Did you work out why this happened? I recall reading many Ubuntu threads where people had installed various intensity utilities and manual control got stuffed up because those utilities would run in the background and immediately reset any manual changes.
You dont thing that was contributing to the problem with the backlight coming back on?
I found in bionicpup64 this application (Redshift Gui) which distributes the brightness in relation to the time of day and the latitude where the PC is located; on my Asus kd55 works very well.
