After a system update on the 15th, xfree86 stopped working giving segfaults and 'io error 104's. I case this happened to anyone else I solved the problem by downgrading glibc 2.3.3-1 to 2.3.2-3.It's probably video card specific cause I didn't have any problems with my laptop (Nvidia) whereas my desktop is an older ATI Mach64 card.
