Which Nvidia driver are you using?
What is the terminal output of
uname -a
i cannot even find the nvidia server settings, i feel like there used to be a screen with a penguin on it that would reflect that info and its nowhere to be found. again tho, still learning all of this
Linux ZorinOS-Latitude-E6430 5.13.0-41-generic #46~20.04.1-Ubuntu SMP Wed Apr 20 13:16:21 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
Hmmm?
Ok so... I am on kernel 5.17.2, cuz I'm a dirty rat...
Isn't Zorin OS 16.1 currently on the 5.13.0-41 kernel? Or has it gotten a newer one lately?
that im unsure of, i know i have 5.13.0-40 in the recovery but when i go into that it doesnt let me past that flashing cursor screen.
Can you follow the steps here:
To set the 5.13.0-41 kernel as the default boot?
Once done, test with a few reboots. If it all looks good, you should be safe to perform regular upgrades and updates in the future without this trouble...
So far, no good. I’m still getting stuck at the flashing cursor screen at boot.
Which kernel are you booting into that you get that?
Or does it matter? Does it boot to desktop if you use recovery - any kernel?
It will only boot to desktop in recover under the above kernel
As of right now this is the only way I can get into the computer.
Ok, so it may be the Nvidia drivers.
Can you please run...
sudo apt-get remove --purge '^nvidia-.*' && sudo dkms remove nvidia
sudo apt install nvidia-driver-390
Once done... UNDO the Grub File change to set the default kernel...
Then try a reboot and test...
“Sudo dkms remove nvidia” prompts an error message invalid number of parameters passed, usage remove module/version —all
Module/version — k(kernel-version)
That's fine - you may have not had the driver installed with dkms
just do:
sudo apt-get remove --purge '^nvidia-.*'
sudo apt install nvidia-driver-390
5.13.0-41 is the current for 16.1 for Pro Lite

We are back in business after that. So let me ask now. How to I get all the, what I perceive to be monitoring tests, from matrixing on my screen when I power on and power off.
This only just started at the same time as the other issue.
sudo nano /etc/default/grub
Please paste the entire line that starts with:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
Also:
GRUB_CMDLINE_LINUX=""
Thanks, glad you are still helping after I... came in like a wrecking ball...
It looks like your Nvidia card will only work with the 390 driver.
So, we need to lock that in.
sudo apt-mark hold nvidia-driver-390
Im working atm, had to step away for a bit to address some misbehaving servers. 
Glad it all got sorted

Question however is what this seems like a cooperation issue between the driver and something in the update, wouldn’t that be addressed in the future? I’d hate to miss out on any performance or stability updates to the driver unless that really isn’t an issue
Such as the 510 driver which looks to have a huge list of improvements, although that ones in beta right now. Even 470 looks to have some fixes.
