I installed Zorin 15.3 a while ago and I've been accepting the software updates.
This last week there was an update that afterwards resulted in a black screen on boot. Launching in safe modes hung here

Can you boot into Recovery Menu
https://wiki.ubuntu.com/RecoveryMode
Then Drop to Prompt.
In the terminal from the Recovery Menu, edit grub file:
sudo nano /etc/default/grub
Find the line that looks like:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
And add the boot parameter acpi=off
(You may also include nomodeset
) so it looks like:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset acpi=off"
Hit ctrl+x to exit, then the y
key to say yes to save, then the enter
key to save as current configuration.
Back in the terminal, run
sudo update-grub
Reboot and test.
If this does not work, then please try rolling back to a previous kernel (usually you can select it from the recovery menu- choose what to Boot From after selecting to Boot from recovery. )
If you get access to your desktop, you may try running from terminal:
sudo apt full upgrade
sudo dpkg –configure -a
sudo apt-get install -f
To fully update and make any repairs to broken packages.
