I have bought an HP Pavilion 15z-eh000 with AMD Ryzen 4700u and Vega 8.
When installing Zorin I cannot get the maximum screen resolution nor have I been able to make the Wifi work.
I have followed the steps to the letter and I could not make it work, I also tried to install the AMD Pro Drivers even so everything remains the same (I also damaged the system a couple of times hahahah).
What could you recommend me to do?
Thanks in advance
I was able to solve the resolution with the following method:
open the file
sudo nano /etc/default/grub
find the line
edit 640x480 to your resolution eg: 1920x1080，并remove the #
Update by the command
Then reboot your computer.
After executing the command
sudo lshw -c network
I get the following answer

sudo apt install net-tools then again the earlier command.

ip link set wlo1 up?
ip link set wlo1 up

sudo ip link set wlo1 up

This mentions updating the kernel but yours is already updated.
Not the exact issue as yours but can you indulge me and check if Secure Boot is disabled in BIOS?
Other than that, your Settings → Wifi → uppermost toggle switch is turned on, yes?
After an intense search, I have been able to solve the problem by doing the following method:
Link: PPA for bug-1888647 : You-Sheng Yang
sudo add-apt-repository ppa:vicamo/ppa-1888647
sudo apt-get update
And now the WIFI works fine!!!
Thanks for the help, there is only one problem with the screen brightness adjustment … If I find how to do it then I will make a post and answer the solution.
