Details I should have included: I should have said that a normal root prompt follows that error message on tty 7 after I log out.
And I forgot this: If I wait a while, more output appears in tty7 spontaneously, specifically these 3 lines repeated at long intervals (presumably 3 minutes): [481.838217] INFO task Xorg:1188 blocked for more than 120 seconds [481.838272] Not tainted 3.13.8-32-generic #57 Ubuntu [481.838302]"echo 8 > /proc/sys/kernel/hung_task_timout_secs" disables this message I say the "same" lines. Presumably the numbers at the beginning are time stamps and change. And I'm sure I've changed kernels since I copied that down with pen and paper. To me it looks like something is preventing x from starting.
