Black screen with cursor after login – works only after pressing Win+L (different login screen appearance)

I already tried forcing NVIDIA earlier using sudo prime-select nvidia, but it didn’t change anything. Now the issue occurs randomly. Sometimes after boot I can log in normally, and sometimes I get a black screen with a cursor and have to lock and unlock the session (Win + L) to be able to log in properly.

Is this a fresh Installation? If yes: Did You installed Zorin with Nvidia Drivers?

Yes, I installed the system directly on a separate SSD. There was no operating system or any data on it before. During the installation, I selected the option to install the proprietary NVIDIA drivers.

Would You be willing to try it with a fresh Install? But then without the Nvidia Drivers. You can install them after the Installation. And switching to X11, too. Check if Secure Boot and Fast Boot in BIOS are disabled and if Windows should be installed, if Fast Start-Up in Windows is disabled? Does Your BIOS run in UEFI or Legacy Mode? What Tool did You use to create the Bootstick? Did You checked the Checksum of the ISO?

I would prefer not to reinstall the system, as I’ve already been working on it for a while, with all my settings configured and programs installed, and I don’t have a separate /home partition. I’m using X11. Secure Boot and Fast Boot are disabled. I don’t currently have Windows on this computer. The BIOS is running in UEFI mode. If I remember correctly, I used Rufus to create the bootable USB because balenaEtcher didn’t work and caused a lot of issues. As far as I remember, the checksum matched, and I think Zorin also checked if everything was okay during the boot process from the USB.

Can You remember if You had chosen in Rufus on the ''Partition Sheme'' Option GPT for Your UEFI BIOS?

Another Thing: You could try it with uninstall and then install again the Nvidia Driver. Type

sudo apt purge nvidia* libnvidia*

for deleting all current Nvidia Stuff. And then

sudo apt autoremove

for removing File Rests. But please take a Look at the Files in the List before You delete them. Then for install the Driver type

sudo apt install nvidia-driver-580 nvidia-dkms-580

If You want to try a different Driver Version, simply replace the 580 with the Number of the Driver Version, You want use. For Example 550 or 570.

As far as I remember, Rufus was set correctly to GPT for UEFI.

I reinstalled the NVIDIA drivers to version 535, but the problem still persists.

And when You try the 550 Driver?

Even with the 550, 570, and 580 drivers.
