Save Changes Kernel Edit

Hi, everyone.

I want to try this for my freezing problem:

So, I add the line just how he says, but I don’t know how can I save the changes in the kernel.

After add/change the line, I do Ctrl+x to boot my system, but I really don’t know if I saved the changes. On my first try, my system froze again after just one minute of use (kernel 5.6.15).

If someone wants to share with me the correct way to save the changes in the kernel, I’ll be grateful.


If you changed a kernel parameter on the GRUB menu, it will be active for that session until you shut down. So, if after that entry you are still experiencing problems, it is not because you didn’t save your change – something else is wrong.
