I’ve been pulling my hair out trying to get my RTX 5080 working properly on a fresh install of Ubuntu 24.04. Thought I’d share my steps so far and ask for help hopefully, someone sees what I missed.
System Specs:
CPU: Ryzen 7 9800X3D
GPU: NVIDIA RTX 5080
Ubuntu 24.04 LTS
Kernel: 6.12.3 (manually installed from Ubuntu Mainline PPA)
Secure Boot: Disabled
I need full support for my RTX 5080 with dual monitors, which doesn't work with the open-source NVIDIA drivers. I’m trying to install the proprietary NVIDIA drivers (.run) from their website.
Windows 11 works perfectly fine on this card and CPU combo. Not a GPU issue.
What I’ve Tried:
Clean installed kernel 6.12.3 using .deb packages from Ubuntu mainline.
Disabled Secure Boot in BIOS.
Cleaned up all NVIDIA packages:
sudo apt purge 'nvidia' 'libnvidia' 'xserver-xorg-video-nvidia*'
- Also removed open kernel modules: linux-object-nvidia-, linux-signature-nvidia-
(As it was trying to load these instead and causing issues)
Confirmed dkms status and dpkg -l | grep nvidia are totally clean.
Installed NVIDIA-Linux-x86_64-570.133.07.run with: --compat32-libdir=/usr/lib32
nvidia-smi fails with:
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver.
- dmesg | grep -i nvidia shows:
NVRM: The NVIDIA GPU 0000:01:00.0 ... requires the NVIDIA open kernel modules.
- Tried 570.86.16 which is Beta currently, and recommended by LEVELONETECHS post by Wendell https://forum.level1techs.com/t/linux-rtx-5090-and-5080-launnch-kernel-upgrade-better-perf-install-drivers/225116
Has anyone gotten the proprietary NVIDIA driver working with a 5080 on Linux recently?
Is the RTX 5080 now hard-locked to the open kernel modules, even for .run installs?
Any known-good kernel + driver version combos I should try?
