trying to sort out krandr-trinity

greets, good people! there are worse problems to have, but i'd like to sort this one, if it can be done. i have a main monitor, which os a 27-inch LG running at 1920x1080. it's a calibrated monitor and i do a lot of pictures, so its happiness is important to me. on a shelf above it i have an acer 24-inch, at 1920x1200. both are attached to a nvidia 630 card using dvi-d cables. using the resize and rotate application from trinity 3.5.13.2, my choices are 3840x1200 or just one monitor. to get from one to the other i must send the mouse off the right side of the master screen (the acer, but i think that that's because of how i have 'em coming from the card, and i shall reverse them. also, my screen background is cut in two. in that it is an application, that makes things kind of weird. so. is there some configuration that would allow me to have my background on one (or both) of the screens separately? more important, is there some way with krandr to use both screens at native resolution? finally, is there a way to set it up so that i take things off the top of the bottom screen to get to the top one, instead of off to the right? i figure that it's either fairly simple or all but impossible. and that it's scarcely an earth-shattering issue. but if anyone knows how to resolve this, pardon the pun, i would much appreciate it. thanks in advance. -- dep The shortest distance between you and playing great acoustic guitar: the great new instructional DVDs from Marjorie Thompson, available at www.MarjorieThompson.com
