###What I ran into Strolling through the keys in dconf-editor, looking for something else, I ran into the screen's information in

/org/compiz/profiles/unity/plugins/core/outputs

which showed the values:

['1680x1050+0+0', '1280x1024+1680+0']

on my system.

This surprised me a bit. I use to get this information, parsed from the output of xrandr.
Since dconf is usually the preferred way to retrieve settings data, I was curious to the timing of both:

xrandr:

real    0m0.067s
user    0m0.000s
sys     0m0.003s

dconf read /org/compiz/profiles/unity/plugins/core/outputs:

real    0m0.004s
user    0m0.000s
sys     0m0.003s

...which shows a dramatic difference.

A great part of my answers around here include a background script. In many cases I use xrandr in a periodical loop. In other cases I use xrandr only at startup of the script to "save fuel", while it would be more elegant to be able to update the information while the script is running (e.g. when an external screen is connected).

###However Editing in the "new insight" would involve many answers in my case. I wouldn't want to be suspected of abusing the system to get older posts to the front page.

My question is therefore, before flooding the site with edited older posts:

Is it "not done" to serial- edit your own posts?
