Hi! I installed a T2000 MXM card into my Dell m4800, everything is installed correctly. Temps are fine and the card is performing great. However, I have an eDP model with the UHD screen. It currently displays from HDMI and the other ports, but the internal screen will not come on. I have checked and Optimus is not an option in my bios, and have read that the eDP motherboards don't allow it? Currently running Linux Mint. and have run out of ideas after trying out a bunch of different drivers. Can anyone help me? Do I need to try coreboot or something? Hopefully I can figure this out.
