Hi,
I recently purchased a Lenovo laptop with a Quattro T2000 graphics card. I installed Linux Mint 19.3 and had difficulty connecting a second screen (It has a 5.0.0 kernel). I fixed the problem by installing a 5.3.18 kernel; however, I noted that the nvidia-440 driver is not compatible with the 5.4, 5.5 and 5.6 kernels. This presents a problem for those installing Ubuntu 20.04 or Linux Mint 20 which releases next month, I imagine with a 5.6 based kernel. When do Nvidia release a supporting driver for the newer kernels ?
