Xorg freeze on shutdown

[Lisa Nelson]

The system was suspended, it recovered perfectly.
When I did a shutdown, the system hung with a message about waiting for Xorg.
After several minutes, I pressed the power button once and the system responded with another message about sending sigkill to Xorg. Still didn't shutdown and went into the 'waiting for Xorg' again.
I held the power button and turned the system off. Not sure if I can reproduce this, or what logs would help with the problem.

We would like to see the system log of a prior boot where the freeze occurred. To do that please:

1. Reproduce the freeze again.

2. Reboot, log in and immediately run:

   journalctl -b-1 > prevboot.txt

   and then attach the resulting text file here.

I will repeat the sequence and when it happens again I'll attach the
requested file.  It might take a while as it doesn't happen often.
