# One way to build this is with:

# automon.sh -- automatically configures multiple monitors.

# I use this script on Arch Linux.  This handles my personal monitor setup more
# correctly and robustly than either Ubuntu or Windows 7, however it is only
# designed to work on my laptop.
#
# On that laptop it always calls "xrandr" using the exactly the same arguments.
# The --auto option in xrandr is clever enough to do the rest.  One day this
# script might become more flexible.

I used to think that

ssh -X me@some.box

"just bloody worked". However this might not work - ssh must play ball on both sides of the link. On the remote (ssh server, X client) sshd must sit behind some port, tell Xlib to send X11 requests to it and then forward them back to you the X server (where the ssh client is). If the remote box is locked down to prevent this, you will get:

X11 forwarding request failed on channel 0

as part of an otherwise working login. As it happens, I am the admin of the remote box in question, so I followed the ArchWiki and went to /etc/ssh/sshd_config and uncommented
