Unloaded: fbdev,modesetting gpu: N/A resolution: 1024x768~76Hz OpenGL: renderer: llvmpipe (LLVM 13.0.1 256 bits) v: 4.5 Mesa 22.0. Steps What I did to get the RTX 3090 working on Ubuntu 20.

First things first, update Ubuntu Once everything is updated, you can do the following steps to get it working. System: Host: mars Kernel:5.15.0-56-generic x86_64 bits: 64 Desktop: GNOME 42.5ĭistro: Ubuntu 22.04.1 LTS (Jammy Jellyfish) Graphics: Device-1: NVIDIA TU106 driver: N/A Display: x11 server: X.Org v: 1.21.1.3 driver: X: loaded: nouveau,vesa The latest driver on Nvidias website for Linux is the 455.23.04 (WHQL) and it lists adding support for the RTX 3090. The script I mention in the comments just use the apt command plus I clean some files in my home directory: nothing revolutionary. I came back to kernel 5.15.0-56-generic and the Nvidia driver still does not work something is broken in my distro.

I have noticed that the kernel was updated too: 6.0.0-1007-oem and my only explanation is that it comes with something incompatible with the Nvidia driver. My Ubuntu 22.04 updated this morning (after I use a standard script using the apt command and some other stuffs to clean my home directory) and the Nvidia driver does not work anymore. You can view the GPU you have and see the recommended driver to install with this command: ubuntu-drivers devices. Since Ubuntu provides the proprietary driver packages via its restricted repositories, user may install NVIDIA driver as easy as a few clicks.
