Shutdown or reboot gives black screen

Hi all !
I have been using ZorinOS for about 5-6 months now and it has been an amazing distribution to me so far, (with some bugs happening rarely, the screen would freeze and I would have to restart it).
Lately I am having some issues, I canno't turn off computer or reboot it, the screen turns black.
I would have to manually hold the power button, or to use REISUB to get back into the login screen.
It started to happen few days ago, after I installed some packages, and I wonder if it has anything to do with secure boot, it got enabled when the packages updated.
I am considering reinstalling ZorinOS or moving to Linux Mint but I wonder if it isn't overkill for now.
Any help is appreciated, thanks!

Hi @aravinth, welcome to the forum!
I was having some problem with frozen screen like yours. I then disabled the "power button action" to "nothing" instead of hibernate on power settings, and I didnt have any problem with it so far. I have Zorin Core with GNOME, if you have other zorin version or DE, it may be a little different to set this.

Thanks for the warm welcome, I have Zorin Core with GNOME as well, I'll look into it.

There are no Zorin OS Updates that can or that will enable Secure Boot in BIOS.
If you are dual booting with Windows, then Secure Boot may do you some good. But if you are only booting Linux, Secure Boot is best disabled.

You may also try rolling back to the previous kernel and testing if shutdown is normal on it - if this began after recent updates.


Thanks I'll need to check the history of updates, to see if/when the kernel got updated. I fully changed to Zorin, so I delete the dual boot option, but somehow it gets enabled each time an update is done
