Not sure that this is fixed. I had the very same problem today and I am using ubuntu 15.10 desktop.
After my wife tried to login an xOrg error was reported. After that my unity desktop refused to load showing only the background image. I have finally got it back running by renaming my ~/.config/dconf/user and subsequently loose my desktop settings. I think this is a very serious issue especially for I was not doing any updates or driver changes before this error occured, it simply happend out of the blue which is quite frightening. Hopefully someone will find time to look into this. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to at-spi2-core in Ubuntu. https://bugs.launchpad.net/bugs/1228567 Title: at-spi2 daemon error messages in .xsession-errors Status in at-spi2-core package in Ubuntu: Fix Released Bug description: Sometimes I get the following messages in .xsession-errors init: at-spi2-registryd main process ended, respawning init: at-spi2-registryd main process ended, respawning init: at-spi2-registryd main process ended, respawning init: at-spi2-registryd main process ended, respawning init: at-spi2-registryd main process ended, respawning init: at-spi2-registryd main process ended, respawning init: at-spi2-registryd main process ended, respawning init: at-spi2-registryd main process ended, respawning init: at-spi2-registryd main process ended, respawning init: at-spi2-registryd main process ended, respawning init: at-spi2-registryd respawning too fast, stopped I use a Lenovo Thinkpad Twist convertible with touch screen, using Onboard in tablet mode.
