[SOLVED] X11 crashes after April 18th system update...

My multi-display XOrg system was working perfectly until I ran the system update last week. Now it crashes and restarts while opening applications.
How can I roll back to the previous X11 version in hopes of fixing this?
64-bit install with a GForce 650 dual DVI output PCIe card.
Thanks!
