My new ZOTAC RTX 5060 Ti (Device ID 20d4) works perfectly in Windows, but on Ubuntu 24.04.3 LTS it never initializes with any NVIDIA driver.

System:

  • MSI PRO B760M-A WiFi

  • Intel 12th Gen CPU

  • Secure Boot: Disabled

  • BIOS Mode: UEFI

  • PEG/PCI_E1 Gen Mode: Gen4

  • Resizable BAR: Enabled

  • Display connected via DP to GPU

Ubuntu kernels tested:

  • 6.8.0-88-generic

  • 6.11 / 6.14 OEM kernels

Drivers tested (all fail):

  • 560.xx → repo install fails or GPU not detected

  • 575.xx → installs but GPU not detected

  • 580.119.02 (.run from NVIDIA) → modules load but GPU does not initialize

Consistent error across all drivers:



nvidia-drm: Failed to allocate NvkmsKapiDevice (GPU ID 0x0000:01:00)
nvidia-smi: No devices were found

Other observations:

  • lspci correctly shows the GPU and NVIDIA audio device

  • Nouveau is blacklisted

  • All NVIDIA kernel modules load (nvidia, nvidia-drm, nvidia-modeset, nvidia-uvm)

  • DKMS fails on OEM kernels, works on 6.8 but GPU still offline

  • BIOS set to PEG only, iGPU disabled / auto tested

Questions:

  1. Is RTX 5060 Ti (Device ID 20d4) fully supported by driver 560/575/580?

  2. Is kernel 6.8 supported for this GPU?

  3. Is this a known issue (KMS allocation failure) for RTX 50-series on Linux?

  4. Is a VBIOS update or upcoming driver required?

I can provide full logs if needed (dmesg, installer log, debug dumps).

Thank you.
