This has worked for me too, thanks. I'm not sure what each part of the config does, but I'm going to have a read and see if changing any bits make any difference to my particular set-up.

I notice that there are two sets of options that have been repeated (specifically tiling and pageflip)---is this intentional?

Edit:

I deleted all of the `Option` lines from the config file, and rebooted. Everything still worked! It appears that many of those are the default values, so just the presence of the file appears to set them. I also found that I was only able to see the Ubuntu login screen on the main laptop screen, but then added a file at `/etc/X11/xorg.conf.d/20-radeon.conf` (the other card in my laptop is an AMD/ATI) with settings:

Section "Device"
Identifier "Radeon"
Driver "radeon"
EndSection

which seems to do something as the login screen now appears on my two external monitors too. I'm not sure why this worked for me, but it appears to have done something!
