Comment 29 for bug 1856387

Hello You-Sheng,
(hope you are well by the way)
I've applied your ppa as described

sudo add-apt-repository ppa:vicamo/ppa-1856387
sudo apt-get update

However I'm not sure what to do next. I assume it installed some packages, but how do I test. I tried a reboot, but I couldn't see how it would work as the latest kernel I have available is 4.15.0-99 and I understand the changes are in the 5... kernels.
Do I need to get or build a new kernel?
