Sytem Specs - Dell Inspirion laptop with Nvidia GeForce 540M graphics card which runs on Linux Mint 13, KDE 4.10, Kernel 3.8.
Google searches show lack of HDMI display support in case of Nvidia Optimus Graphics where the HDMI output is tied to secondary graphics card. Came across a workaround which suggested cloning the session to get HDMI display working.
Am also scared of modifying xorg.conf and breaking the display. Would like to know , if anyone here has tasted success in getting HDMI display work in Optimus laptops. If this works, i can completely forget Windows.
I have bumblebee installed and am able to optirun games / apps fine.
