Comment 9 for bug 1382291

Some feedback from bregma:
"I imagine it's just a matter of writing a script to query the X server (xrandr) and calculating some reasonable scaling factor based on the pixel density, then setting the gsettings value
<bregma> maybe a half-days work for someone who knows Python
<bregma> StephaneVerdy, that bug has some good info on how to write the script (and a link to an example), although in Unity we use a more fine-grained scaling control and allow different scaling on different monitors (probably not an issue for OEM setup)
<bregma> the best bet is to use the GTK devioce info because they work around some broken EDIDs better than X does
