I had cause to re-read bug
<https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=859564> titled
"arandr: doesn't detect when I unplug an external screen"
Depending on how the phrasing of the problem is read it cause could be a
hardware related issue or have an underlying cause in common with my bug
<https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=865535> titled
"arandr: Does not use applied settings on reboot".
Is it correct to send the same email to both bug reports?
I intend to add the model information of my laptop to my report.
