I first installed Ubuntu 18.04.06 LTS and had the same problems. Also a lot of hardware didn’t work in 18.04. I found it externally on the internet, but I decided to give up. Later, I found out that it does not support the kernel version and I had to upgrade to 20.04.
Currently only Bluetooth is not working but it doesn’t matter. The biggest problem right now is Nvidia GPU. I also installed the driver from the website, ppa (470-510) but it didn’t change. I tried many methods from forums but failed. When I switch to Nvidia “On-Demond” mode in Prime Profile, there is no problem, but this time AMD External CPU is used in my projects and it is insufficient. In summary, when I switch to Nvidia Performance mode, the system freezes, gets up from time to time, but freezes again.
Thanks in advance for your supports :)
