Hello, I have an HP OMEN Ryzen 7 4800 with a GeForce GTX 1660Ti running a dual boot with Windows 10 and Linux - Ubuntu 20.04.2 LTS with 5.14.0-1020-oem kernel. I started the following thread some time ago: > [@Installed driver is not loading returning the message - ERROR: NVIDIA driver is not loaded](https://forums.developer.nvidia.com/t/installed-driver-is-not-loading-returning-the-message-error-nvidia-driver-is-not-loaded/167202): > > Hello, I have an HP OMEN Ryzen 7 4800 with a GeForce GTX 1660Ti running a dual boot with Windows 10 and Linux - Ubuntu 20.04.2 LTS with 5.8 kernel. In Windows everything work with no problem. In Linux however, the Nvidia drivers do not seem to load even though the card itself is recognized by the OS and the driver 450 is installed as well. The main reason I need to get the card to work is to connect the laptop to an external display. Please note that it is the first time I am using Linux an… My problem was solved back then, but one day out of the blue, without doing anything that could change the “working” configuration (to my knowledge), upon booting my system up my laptop’s screen looked like static TV black and white noise. After searching the issue online I found that kernel 5.13 was responsible for this bug. After switching to kernel 5.11 or 5.14 the main screen was working again. The problem is that I could not make my external monitor work anymore. It worked with kernel 5.13(only the external monitor)until I switched my nvidia prime options to “Power saving mode (Intel)” trying to solve the problem. I could not make anything work so far, even though I tried to follow each step of the solution of my previous thread.

The command for re-installing would be: `sudo apt reinstall` … But yeah, you already have the headers installed. So you would need to dkms install the driver (not sure up to which kernel the 460 driver has support for) for your current kernel. It is installed for 5.13.0-27 - but that one is buggy, so try it for the 5.14 one. And why not go with the current production release? `sudo apt install nvidia-driver-470` ---

@Mart Actually the 460 driver for 5.13.0-27 was working just fine. The bug was with the laptop’s main screen which was using the AMD card. The external monitor was using NVIDIA connected through the DP. But I tried to install the 470 driver with `sudo apt install nvidia-driver-470` but something is wrong here too: ```auto Reading package lists...

nvidiafb is loading, but it should be blacklisted. Please look for nvidia blacklist files: grep -r nvidia /etc/modprobe.d /lib/modprobe.d if you do find a file with the entry: `blacklist nvidia`, that entry should be removed. if you do NOT find a file with the entry `blacklist nvidiafb`, you should create one (ie /etc/modprobe.de/blacklist-nvidiafb.conf) with exactly that content. If any of this applies, then run `sudo update-initramfs -u` and reboot. ---
