I did that a while back, when I set the monitors up this way. They were
arranged correctly once I logged in. It's just in lightdm that they were
wrong. They are correct now (I actually don't know why, unless it's
ignoring the hash mark for that line), but I get those errors, which might
be related to it not going into suspend overnight.
I modified lightdm's config on 20 May (so says my log), but:
eben@cerberus:~$ sudo journalctl | grep xrandr | uniq -c --check-chars=6

There are no errors on the 23rd related to xrandr, so I suspect something
happened on the 24th.
<investigation happens>
The logged event right before lightdm started acting up was
May 24 21:25:01 cerberus dbus-daemon[1362]: [session uid=1000 pid=1362]
Activating service name='org.xfce.Xfconf' req>
May 24 21:25:01 cerberus dbus-daemon[1362]: [session uid=1000 pid=1362]
Successfully activated service 'org.xfce.Xfco>
Maybe that dbus update was bad? Or I only updated part of it or something?
