I am trying to install NVIDIA driver on Ubuntu 20.04. However, I am getting an error ERROR: Unable to load the kernel module 'nvidia.ko'. This happens most frequently when this kernel module was built against the wrong or improperly configured kernel sources, with a version of gcc that differs from the one used to build the target kernel, or i f another driver, such as nouveau, is present and prevents the NVIDIA kernel module from obtaining ownership of the NVIDIA device(s), or no NVIDIA device installed in this system is supported by this NVIDIA Linux graphics driver release.

Thank you very much for your reply! In the provided link, there is no solution for this issue. I would appreciate it if you could give more precise instructions for the solution.

Tesla cards often have significantly larger than normal BAR size requirements and so may need the appropriate BIOS settings in order to achieve this. This is one of the reasons these cards are sold fitted to Nvidia certified systems. See Roberts reply, (second post): Plugging Tesla K80 results in PCI resource allocation error Also, certified systems, here and here.

[image] tbezdan: could you provide an example of how to do the BIOS settings for the BAR size by using ssh? Sorry, I’ve never needed to do this and have never owned a PC that would enable it to be done. Google may help.

The problem is that every board manufacturer may have different settings in the BIOS. And some lower end mainboard don’t offer the required setting at all. Updating the BIOS to the latest published version from the vendor may help. Try enabling “Above 4G decoding” in the BIOS, which may appear under PCI subsystem settings. Some higher end, and most workstation and server mainboards should have this.

[image] cbuchner1: Updating the BIOS to the latest published version from the vendor may help It looks like the installation was successful now, but when I run nvidia-smi, I get the following: Failed to initialize NVML: Driver/library version mismatch I tried to remove and uninstall nvidia, then to install it again, but I am still getting the same.

Does the error go away after a reboot? Usually that is a sign of the nvidia driver binary not matching the loaded kernel module. I have seen this error occur on forced driver security updates in Ubuntu that were installed by the automatic update mechanism. I would get this error until I finally rebooted. If the error persists, try to find out from which package the current nvidia-smi binary was installed and see if that matches the loaded nvidia driver and kernel module.

Yes, I rebooted it. And checked the versions. NVRM: this kernel module has the version 515.65.01. Please NVRM: make sure that this kernel module and all NVIDIA driver NVRM: components have the same version.

Thank you @rs277 , I am new to Ubuntu, could you provide an example of how to do the BIOS settings for the BAR size by using ssh?
