If I set my login to automatic, I get very close symptoms to bug #1380050. Screen is black for few seconds and Xorg peaks to 10% CPU usage at that time.

It usually took half a second, so this looks like a bug. Right before these show up, a short black frame indicates some component crashed and was restarted. After this delay the performance is fine as usual. I tried to debug the performance drop during these 10 seconds with top in the terminal, but did not know what to look for. Unsurprisingly most active processes were sysvinit, xorg, compiz and unity, but all about 1% CPU usage at maximum. First occurance has been about one week ago, it did not happen directly after the fresh installation of the 14.04.1 image . I don't use proprietary drivers and didn't mess with xorg edgers if I remember correctly. Could be a bug of unity or compiz, too.
