I'm glad you mentioned Xorg.0.log; it prompted me to look at mine, and I 
found I didn't have an fbdev driver. I found I needed to add USE=evdev to 
dev-qt/qtgui and remerge qtgui.

That ought to have been picked up from INPUT_DEVICES="evdev" in make.conf. 
Looks like a bug.

I think this should fix the flickering display I mentioned a few days ago. 
Have to wait and see.
