Segfault using Two Monitors

[csnate]

I am trying to use dual-monitors on a Dell Optiplex 3020. I have Intel and AMD graphics. When I try to use dual-monitors (one monitor per graphics adapter), X crashes with a segmentation fault.

Anyway I can get dual monitors to work? This used to work before I upgraded to 7.4.
