External monitor wired to Nvidia card not working on 20.04

  • 772

So, I've got this weird Nvidia + Intel combination, where HDMI is wired to Nvidia card, so I can't use HDMI without switching to Nvidia driver. When I was using 19.10, it was as simple as opening Nvidia Settings and enabling Nvidia (Perofrmance mode) in PRIME Profiles. But now it doesn't work! If I switch the GPUs it doesn't enable the screen. It doesn't even show nvidia-specific settings which were there earlier, like GPU frequencies, connected monitors, all that stuff. Here is how it looks like:

Here is lshw -c video output:

lspci reports I'm using Nvidia driver:

Software and updates window tells me same thing: I'm running nvidia-driver-440. What is broken here and how do I fix it?

UPD: It wasn't an upgrade from older system, I made a clean install

  1. Thank you for the workaround. It works! but a small correction - There is no 's' in 'driver'

    so you do:

    sudo apt install nvidia-driver-435

  2. So, as a workaround, one can downgrade, it solves the issue. For example, to downgrade to v435:

    sudo apt-get install nvidia-driver-435
