Thank you very much for the note. Your tip of running "xrandr --auto"
works neatly when I log in and type it. But I still have a problem -
how do I automate this at boot up? When I boot the laptop with the lid
closed, keeping it plugged to the monitor, it fails to display
anything. I then open the laptop lid and it now throws me the laptop
screen display on the monitor. Then I log in and run "xrandr --auto"
and the display  resizes to the monitor size. I want to automate this.
How I can do so ?

I could bind "xrandr --auto" to a function key, but it will still
throw me the laptop size screen on the monitor display.

Regards,
