It is not the autolock - autolock is disabled.

Well, in one of those chances where I was lucky to get the screen back, I installed ssh , and managed to capture the messages from dmesg when the screen goes through the process of desperately trying to come back to life

Below is the output - The multiple "performing LCD ESD recovery" are the attempts, and they are accompanied by a 'glowing' LCD . When that line stops, means the LCD has given up - and another sequence starts when I touch the screen again.

Does this output throw any light on the problem ?
