Sorry, I don't understand the difference between Kernels. I have the Ubuntu Kernel 5.5.1 installed from Ubuntu. Not the official Kernel from Kernel.org. I downgraded to the official kernel that works with 18.04 LTS that is installed by default for filling out this bug report. I am still uncertain with Ubuntu because have not been using it long as I have occasionally stopped using it because of hardware limitations with newer hardware.
