Dual GPU AMD and Nvidia cannot use TV-Port (Component)
#1
This is a pretty advanced problem. I use an MSI Radeon RX 460 2GB model video card for day to day gaming and primary monitor viewing. I would like to be able to use my secondary video card Nvidia GeForce 8600 GTS. In particular, TV-Port component video feature (NTSC 60Hz 640x480). On windows this can be easily accomplished by installing Nvidia drivers or even just going into default advanced settings in some cases. My problem here is not only have I had mixed results from TV port on linux, but I have to use amdgpu drivers in order to even see anything on my primary monitor. I have also tried installing Nvidia drivers alongside existing amdgpu ones but it just reboots into the same black screen I got after install. I looked a little into Dual GPU on linux but most of that seems to be targeted at laptops with Nvidia and Intel graphics. Is this possible? Thanks
