I have the Samsung 530U3C ultrabook with Intel HD4000 graphics. I have Ubuntu 13.04 (fresh install). The laptop is connected to the TV HDMI port, but it isn't detected by the laptop. The TV shows that it's HDMI port is used.
In Windows everything works flawlessly: detection, image, sound.
I also installed the intel drivers using Intel Linux Graphics Drivers application.
Do you have any idea what can I do next?
