Problem: The HDMI display port is failing.
There could be a problem with dual display. The command prime-select may help solve the problem by forcing a Hybrid display model with NVIDIA drivers and Intel drivers.
sudo apt install nvidia-prime
sudo prime-select on-demand
Note that command sudo prime-select nvidia will only select nvidia drivers, meaning that only the external device will be on.
On the other hand, command sudo prime-select intel will only select the laptop display, which usually relies on an intel drivers.
The above statements describe what is likely to occur, but only on-demand guarantees both drivers to be activated if they can be activated.
Problem: The HDMI display port doesn’t work. The monitors do not turn up. All other options above have been tried.
Sometimes configuration can be automatically changed. In those cases, a re-installation of the drivers may solve this problem.
sudo apt remove --purge '^nvidia-.*'
sudo ubuntu-drivers autoinstall
sudo reboot
