Hi, I have a notebook where it appears a fresh install of natty has detected 2 screens as being present, and set them to be mirrored.

However, there is only one screen present.

It's a Hp 5320m, with a Intel HD graphics.

Here's what the unity test says:

~$ /usr/lib/nux/unity_support_test -p
OpenGL vendor string: Tungsten Graphics, Inc
OpenGL renderer string: Mesa DRI Intel(R) Ironlake Mobile GEM 20100330 DEVELOPMENT
OpenGL version string: 2.1 Mesa 7.10.2

Not software rendered: yes
Not blacklisted: yes
GLX fbconfig: yes
GLX texture from pixmap: yes
GL npot or rect textures: yes
GL vertex program: yes
GL fragment program: yes
GL vertex buffer object: yes
GL framebuffer object: yes
GL version is 1.4+: yes

Unity supported: yes

Here is what i see in monitors when i uncheck 'mirrored'

If i disable either of these two monitors, then i lose the screen for both- oops.

Really don't know how to troubleshoot this, appreciate anyhelp!

While the above is weird, the end goal is to attach an external monitor via my hp displayport- no end of trouble trying to re-configure this currently.

Makes no difference if i use the VGA connector- still end up with 3 different monitors, none of which are configurable :(

Is there anyway to force re-detection of my graphics hardware?
