I install Ubuntu 11.10 into my laptop with dual-boot. In windows, I cannot output both is laptop monitor and projector. But in Ubuntu, it fail to.
Then I install Ubuntu in my pendrive with Unetbootin, and boot it with another PC, still no luck. That PC has no graphic card, so I believe it is not the graphic card issue that causes the projector to not working.
Any idea? I want to output to a projector
