Hi Chris
Here is the dmesg that you asked for
http://pastebin.com/raw.php?i=RuN5s9nw
It booted up to the ubuntu login screen fine, showing on both monitors.
As soon as i logged in the primary 30" went blank but the 20.1" was still
showing its part of the desktop.
I pulled the signal cable out

Title:
Ivybridge dual monitor set resolution warning in
ironlake_crtc_mode_set
To manage
The flags mismatch warning is not critical (we're missing a bit of code
to setup the pipe state correctly before the warning). Can you paste the
full dmesg with drm.debug=6?

Hi Chris,
I tried the kernel 3.10.0-994-generic #201306190448 from
http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-nightly/ from
19-Jun-2013 and still no luck
My log is littered with these warnings
[ 138.868696] [drm:intel_pipe_config_compare] *ERROR* mismatch in
adjusted_mode.flags
We have moved on to a new issue! That bug is fixed in drm-intel-nightly.
