I've attached my Xorg.0.log.old which includes the segfault backtrace. I'm like a newborn baby when it comes to compiling and Gentoo doesn't have a debug USE flag for xf86-video-intel or xorg-server so I can't help there. Is there a different package I should check for a debug USE flag? - Grant P.S. Sorry for the multiple sends. -------------- next part -------------- A non-text attachment was scrubbed...
