Looked at the description of 1357746 which indicates problem caused by the latest level of xserver-xorg-video-intel. The "boot hang on black screen" forum entry (see Ubuntu Development Version) I had with Gnome also involved the same component. In trying to debug the Gnome failure it was recommended to go to an earlier level of xserver-xorg-video- intel. The only way I knew to do this was to copy the executable files (/usr/lib/xorg/modules/drivers/intel_drv.so, /usr/lib/libI810XvMC.so.1.0.0, and /usr/lib/libIntelXvMC.so.1.0.0) from my working 14.04 system to the failing 14.10 Gnome system. When I booded the modified 14.10 system it came up and ran with only a minor screen refresh slowness. Since this fixed the Gnome system I tried it on the Unity system but unless I did something wrong it made no difference. The interesting thing was when I backed off the changes in the Gnome system (replaced the 3 original modules) the system continued to boot OK without any screen refresh slowness.

Submitting problem report on Unity since seems easist to document. I downloaded the Ubuntu 14.10 daily build dated 8/29/14 and went through the install process without any problem. After completion of the install, doing the first boot of the system, and the login screen my desktop background is displayed with desktop ICONs. There is no Ubuntu banner at the top of the screen or any Unity launch bar on the left. My only option was to ctl-alt-f1 and build/save a bug report which I using to report under the working 14.04 system on this same desktop.
