I'm using Debian Testing on a Lenovo T510 Thinkpad whose screen is too

I prefer my 17" diagonal external with a nominal 4:3 aspect ratio.
I am using ARandR Screen Layout Editor 0.1.9.
It reports:

vga monitor as 1280 x 1024 and normal orientation
With those settings it _can_ and *FREQUENTLY* does display what

Frequently does but generally doesn't does not compute.
I'll stand by my summary statement as being literally true.
I'll rephrase it.

This morning started off "worse" than usual.
However I've a gut feeling that I've wandered into at least a partial
explanation. I suspect some variable is "path dependent" rather than
"state dependent". I'll have to work out a test procedure to verity.
I've identified one problem source.
At least sometimes after a power off shut down it comes up with the
laptop display selected as primary.
How can I force it to always come up with the VGA monitor as primary?
I created /home/richard/.screenlayout/VGA-as-master.sh with preferred
settings back when I was experimenting. I had understood ARandR would
use it automatically. It evidently doesn't.
