Hey there I'm a bit of a noob on linux. Can you explain how can I apply this patch?
Hi @juricajelaca, this patch was only useful for testing Linux kernel release candidates as they came out.
There's a new version of the NVIDIA proprietary Linux drivers that already supports Linux 5.14 without any patch, this is probably what you want to install (download it from your distribution's repositories if you can):
https://us.download.nvidia.com/XFree86/Linux-x86_64/470.74/NVIDIA-Linux-x86_64-470.74.run
If you really want to install use the old version of the NVIDIA drivers with this patch, you should do it like this from a terminal:
$ sh NVIDIA-Linux-x86_64-465.31.run --extract-only
$ cd NVIDIA-Linux-x86_64-465.31/kernel/
$ patch -Np1 -i ../../nvidia-fix-linux-5.14.patch
$ cd ..
$ sudo ./nvidia-installer

Woah, thanks for the fast reply :). Guess I'm having some other problems then, cause my graphics won't change from Integrated to nvidia for some reason, even if I installed the latest driver.
thank you soo much! this solved my problem with the 5.14 kernel!!!!
