Can you post the Intel Xorg.0.log as well?

That's what happens when X starts without input or window managers. Try
typing the exec line of your favourite window manager in xinitrc. To
make sure input works, make sure you have udev and xf86-input-evdev
installed. Also make sure the evdev kernel module is loaded. If you
don't want to go that route, you'll have to install the older mouse and
keyboard drivers and make corresponding sections for those in xorg.conf.
