strange video audio and keyboard issue after upgrade

[Felix Wong]

sorry about that. for some reason i don't get a copy of my own
post/email and just digest versions of the mailing list. (i have the
setting on for "Receive your own posts to the list?" as well, but it
somehow doesn't deliver the my own post to me.) i have switched to
getting individual copies of all emails.

tailing the syslog file doesn't show any changes. the file does not
advance at all when i unplugged either the hdmi or the displayport.

Please note that in this list the convention is to insert your reply
at the appropriate point in the previous mail, which makes it easier
to follow the thread.  Thanks.
With the second monitor disconnected open a terminal and run
tail -f /var/log/syslog
then plug in the monitor and see what gets added to the log.  If it
doesn't help you then copy/paste here what you see added to the log.
You can copy from the terminal using Ctrl-Shift-C.  Hopefully that
will provide some clues.
