[Bug 1010964] Re: Precise on Intel N10 Graphics detects two displays when there is only one
Mark Ellse, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com
/daily-live/current/ .
If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:
apport-collect -p linux <replace-with-bug-number>
Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER
where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc5
This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing
If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER
As well, please remove the tag:
needs-upstream-testing
Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
Precise on Intel N10 Graphics detects two displays when there is only
one
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
After installing Precise on Intel D525 Atom motherboard, which has
Intel N10 Graphics, Ubuntu detects two monitors: one the correct one;
the other 'Laptop', the latter of which doesn't exist. By default,
'Mirror displays' is selected and the VGA output behaves as though it
is driving a low-resolution laptop display.
Behavious evident in Kernels 3.2, 3.3 and 3.4.
Workaround: Deselect 'Mirror Displays', click on 'Laptop' and turn Laptop off.
