Devin:

i've done it on Fedora 20, don't know if that's similar enough to C7
or not, to work the same way, Uinsg Nvidia proprietary driver.

A couple of caveatrs:
1. I don't remember the details, but if you're interested, I can dig
for whatever info I used when figurinig it out;
2. I got two "independent" monitors, but that means you can't drag things
across monitors. but there also are no menus in the panels of the second
monitor, and no desktop icons, by default, so it's hard to start programs
on the 2nd monitor. I recall finding an XML file (somewhere???) that
contains what appears to be the setup info for the main monitor, so it
may be possible to either hack that file, or create some other file
with similar info in it, that will cause the second monitor to be a
full-fledged workstation in its own right.

YMMV!

Let me know if you need me to dig around for info.
