Dell G15 5511 Hybrid Intel-Nvidia RTX 3050 ti. How to correctly enable the dedicated card?

Hello, I would like to know how I can have control over the hybrid options through the terminal.

  • At the moment only the laptop display works with Intel video, but the Nvidia driver is installed and apparently active but not selected.

  • I have no video output from the HDMI output.

  • At the moment I have not added anything manually to /etc/X11/.

I have:

  • Dell G15 5511 laptop

  • Intel + Nvidia RTX 3050 ti,

  • Video is hybrid.

  • Debian Bookworm

  • Linux Kernel 5.15.0-2-amd64

  • Nvidia Driver 470.86

What I have done:

  • A fresh install of Debian 11
  • When rebooting into the grub with the E key I entered the options so that the line looks like this: “quiet splash nomodeset”.
  • I have upgraded to Bookworm with non-free and contrib repositories.
  • Then I installed apt-get install nvidia-drivers and apt-get install nvidia-detect.
  • On reboot I don’t use the splash nomodeset option.

$ inxi -G

I suspect this is something to direct towards a Debian support channel as this is unlikely to be a driver issue.
