separate subpixel rendering for each monitor

Hi,

is it possible to configure separate subpixel rendering for each monitor? I use a multi monitor setup with 2 additional inverted screens (via xrandr). Each screen has a RGB subpixel mapping. The font rendering on the inverted screens looks odd, because they would need BGR mappings. Thats my guess at least, tested it via http://www.lagom.nl/lcd-test/subpixel.php

Re: separate subpixel rendering for each monitor

Unfortunately there is no way to have separte subpixel rendering for each monitor.  The library doing the rendering (freetype), would have to know which screen you are on and adjust dynamically.  Plus, suppose you have half of a window on one screen and half on another - it wouldn't know which to choose.

I would like to be able to do this, too, for my rotated monitor.

I am sure it is technically possible, but not without a major redesign of how the applications render the fonts.
