I have Dell model XPS 15 and just installed a fresh Ubuntu 22.04.1 LTS. I have lots of problems installing it at first but after some time I was successful. I also tried to install the "nvidia-drivers-515" drivers. I had some problems with this as well but finally got it instlled.

Ubuntu still seems to be using the integrated card instead of the Nvidia.

This is some output.

➜  ~ lspci -nn | grep -E 'VGA|Display'
00:02.0 VGA compatible controller [0300]: Intel Corporation Alder Lake-P Integrated Graphics Controller [8086:46a6] (rev 0c)

The system recognize both cards but integrated one is being used.

From the following output Nvidia seams to be sleeping or im missing something?

Why both cards are active? How can i make sure that I'm using the Nvidia and the drivers are working properly?

  • Hi. the only way to offer any help is to know what the exact problems you were having and what you did to finally get it working. Please edit the question, not as comments and add this info. – David Oct 11 '22 at 05:40
  • You can switch graphics by nvidia-prime. I don't see any problems. – Pilot6 Oct 11 '22 at 07:22
  • Please add output of nvidia-prime query and glxinfo | grep OpenGL to your question. It will show if Nvidia is used. – Pilot6 Oct 11 '22 at 07:23
  • I didn't find the command and im not sure how to install it zsh: command not found: nvidia-prime – IvanAK Oct 11 '22 at 07:29
  • And i add the output of the other command to the question. – IvanAK Oct 11 '22 at 08:24
  • nvidia-prime should be installed but if not you surely can and should install it like any other package: sudo apt install nvidia-prime . It is indeed required for switching graphics. I wonder what else is missing... How exactly have you installed the Nvidia drivers?* – ChanganAuto Oct 11 '22 at 12:31

    When you install Ubuntu and have nVidia, you need to choose to boot in Safe Mode & choose to install restricted drivers. Then nVidia druver is installed automatically. Try sudo ubuntu-drivers autoinstall But if you manually installed wrong driver, you must purge first or you get conflicts. ppa not required anymore: https://askubuntu.com/questions/1026179/how-to-install-a-gtx-1060 & https://askubuntu.com/questions/61396/how-do-i-install-the-nvidia-drivers – oldfred Oct 11 '22 at 12:55
  • I have installed with sudo apt install nvidia-driver-515 -y. How to choose to install restricted drivers? How should i install it via apt or differently? Regarding nvidia-prime

nvidia-prime is already the newest version (0.8.17.1).
nvidia-prime set to manually installed.
0 to upgrade, 0 to newly install, 0 to remove and 6 not to upgrade.
➜~ nvidia-p
nvidia-persistenced  nvidia-powerd```
it is there but its missing

  • Also,should i uninstall the current drivers ? – IvanAK Oct 11 '22 at 18:58
  • I have the same problems. Any updates? – Hameda169 Mar 09 '23 at 23:24
  • Try install it via "Additional Drivers". For me was formating the laptop. When boot i wait 15 min on DellXPS15 and during the installation i check the button for installing the drivers and everything. Once installed i update and install the new drivers vie "Additional Drivers". – IvanAK Mar 27 '23 at 09:08
