I have Ubuntu 12.04 on a Dell latitude E6410, I have a problem when using the VGA output I always have dual monitor and can't switch on the "mirror display" toggle under systems setting/displays. It's rather annoying when having to do presentation with a video projector. the option "mirror display" is in light grey and I can"t tick the box.

Thanks for those who might have an idea how to resolve this?

update: driver is: Intel® Ironlake Mobile x86/MMX/SSE2

card something like this ? description: VGA compatible controller product: Core Processor Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 02 width: 64 bits clock: 33MHz
