Subject: RTX 5070 Ti Not Detected in nvidia-smi (Driver Version Mismatch)

Graphics / Linux Linux
1

I’m experiencing an issue with my “GeForce RTX 5070 Ti” on Ubuntu Linux:

  • GPU is detected in lspci, but nvidia-smi shows “No devices found”.

OS: Ubuntu 24.04

Troubleshooting steps I’ve tried:

  1. Disabled Secure Boot.
  2. Added nvidia-drm.modeset=1 to kernel parameters.
  3. Confirmed kernel modules are loaded (lsmod | grep nvidia).

System Info:

  • GPU PCI ID: 10de:2c05 (from lspci -vnnn)
  • Kernel: 6.11.0-25-generic
  • Driver: 570.133.07

Could this be a compatibility issue with the RTX 5070 Ti?
Please advise how to resolve this.

p.s.

[I’ve tried this too]

===========
.Methods attempted & results

  1. Check the driver
    $ lsmod | grep nvidia

Loaded normally (check nvidia, nvidia_drm, etc.)

  1. Secure Boot
    $ sudo mokutil --disable-validation

Already disabled

  1. Add kernel parameters
    $ GRUB_CMDLINE_LINUX=“nvidia-drm.modeset=1” → update-grub >>> ❌ No changes (error persists)

  2. Check Wayland/Xorg
    $ echo $XDG_SESSION_TYPE

❌ No Xorg log file (suspected Wayland session)

  1. Check driver version
    $ dpkg -l | grep nvidia-driver

570.133.07 installed (too recent?)

  1. Downgrade driver
    $ sudo apt purge nvidia-* → sudo apt install nvidia-driver-550 >>> Partially successful (installation complete but nvidia-smi version mismatch)

  2. Manually install official driver
    $ wget NVIDIA-Linux-x86_64-550.67.run → run

Installation successful but NVML version conflict (550.67 vs library mismatch)

  1. Reinstall DKMS
    $ sudo dkms install -m nvidia -v 550.67

Already installed (suspected compatibility issue with kernel 6.11.0-25)
