Comment 2 for bug 24790

Created an attachment (id=4858)
.tgz of the xorg.confs, Xorg.0.logs and xrandr output

G'day,

thanks for looking into this.

If the screens are in descending order (largest to smallest), then three
virtual displays are created:
$ xrandr
 SZ: Pixels Physical Refresh
*0 1024 x 768 ( 306mm x 228mm ) *0
 1 2048 x 768 ( 306mm x 228mm ) 0
 2 2304 x 1024 ( 306mm x 228mm ) 0
Current rotation - normal
Current reflection - none
Rotations possible - normal
Reflections possible - none

This is basically what I want, except I would prefer screen 2 to be the
default, which seems to be controlled by the order the screens are listed in
the display section.

If the screens are given in ascending order, then only the smallest is created:

$ xrandr
 SZ: Pixels Physical Refresh
*0 1024 x 768 ( 306mm x 229mm ) *0
Current rotation - normal
Current reflection - none
Rotations possible - normal
Reflections possible - none

The two larger virtual screens are not created.

I am attaching a tarred gzipped file of the xorg.confs, Xorg.0.logs and the
output of xrandr for the ascending and descending cases.
