Set default kernel and install specific version

Hi,

on my system, kernel 4.18.16 works great but 4.20.8 is a complete disaster for me (slow boot, powertop does not work, dmg gives black screen, etc).

I have googled about this but all answers are very old (i.e. fedora 22 or older), can you help me do:

  1. Set a default grub entry to the kernel I am interested in
  2. Making sure such kernel version doesn't get deleted
  3. Find a way to install specific versions (I'd like to try 4.19.x)
  4. Repeat the above if happy with specific versions

Thanks

Thanks Thanks
