Can't activate "mirror display"
- by Nemo Peeters
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 ?
