I have a similar issue on my desktop. When I boot, most of the time all I get is a black screen with no login window. I can change to a terminal prompt (ctrl + alt +F2) to reboot the computer. Sometimes I can boot to the login screen and use the OS normally but this is probably about 25% of the time.

When I boot, the screen is switched on but remains black. I connected another screen which works fine (VGA or HDMI) but I'm not able to use the primary screen. I tested the kernel drm-intel-nightly/2014-01-23-trusty (http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel- nightly/2014-01-23-trusty/) and it works well.
