Now I am using Ubuntu.
So I need to apply  at least the following change[]1] at least to test
RTL8822CE
wifi card.

I need to compile from source code, then make a memstick image, mount to a
usb stick, then install from the usb pen drive.

If all things going well, dmesg | more | grep WLAN  should return
something? Or how can I test if my wifi card is working.
