Kamal, I have confirmed all of your findings so far, including:
1. by disabling dpms (xset -dpms) the screensaver does not turn off the backlight, and the screen does not get "stuck". 2. (1) does not resolve the issue when caused by running "xset s activate" 3. Your, 1st, method of passing the lock screen in "in the dark" and then adjusting the brightness does cause the backlight to turn back on. 4. Your, 2nd, method of switching to a different tty, closing the lid, opening it and then switching back to the X tty also works as you described.
