I’ve installed the driver 535.54.03 on Ubuntu 22.04.2 LTS, I have a 4070 Ti and can’t detect second screen through HMDI, main screen is detected through DP.
I’ve tried to run nvidia-smi but I get this message: NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
Hey @thaha1, I fixed the issue by performing a fresh installation of the nvidia driver: sudo apt-get remove --purge nvidia-* sudo apt-get install nvidia-driver-535
Finally, rebooting and disabling my BIOS Secure Boot fix it.
Be aware disabling Secure Boot can potentially have some security implications, and if you’re dual-booting with Windows, it might cause issues with that.
