[Pkg-shadow-devel] Bug#659878:

[Plmalternate Plmalternate]

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.

I'm on the waiting list for an email account at

where I'll be philip.mundhenk at protonmail.com
or maybe philip.mundhenk at protonmail.ch
until the DIME project gets off the ground.

Because the Bill of Rights needs to be more than "a literary fiction".
