Hello.
I've been using Zorin OS on my church pc for about 2 months. Since the last sunday, when I'm presenting something using Holyrics, the system completely freezes and I can't do anything. It doesn't happen all the time I start to present.
I've already tried to change from wayland to xorg, install zram and earlyoom, but the freezings persisted. I've tried to use journalctl to see logs from the crashes, but it only shows logs from hours before the freezing.
Here is the output of inxi -Fz:X.Org v: 21.1.11 with: Xwayland v: 23.2.6 driver: X:
Can you follow the steps here, except that you will not be using nomodeset.i915.enable_psr=0 i915.enable_dc=0
There may be times that a user must add a specialized grub parameter in order to overcome an issue.
The purpose of this guide is not to provide parameters, as that would be a case by case basis. It is to provide a guide on how to add one.
To add a parameter, in a terminal (TTY, Recovery Prompt or Terminal Emulator) run:
sudo nano /etc/default/grub
Arrow key down to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" and place your parameter within the quotation tags. For example if you are adding th…
It will look like:GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.enable_psr=0 i915.enable_dc=0"
Tap ctl+o to overwrite, enter key to save current configuration, then tap ctl+x to eXit the editor.
Now, you must run
sudo update-grub
Then, reboot the computer and test if it still freezes.

Did Aravisian's suggestion solve the problem?
I asked because I found another possibility for the source of the freezing problem: You are

Sorry for the late reply. I don't have access to the church computer, just on the weekends I work there. But since I did what you recommend, the computer stopped freezing. Thank you very much!

I use two monitors. The first is the main screen and the second a projector. I use a hdmi to usb too for the camera we use for streaming. Could the system confuse the camera with a GPU output?
Glad to hear (and not surprised) that Aravasian's suggestion seems to have solved the problem. I don't believe the system is confusing the camera with a GPU. But if the problem recurs, try using a powered usb port replicator for the usb to hdmi adapter.

Can you help me?
Today the computer froze again while presenting. What's your take? Would the camera cause the system to freeze?
EDIT: after freezing and rebooting, the computer soon showed a kernel panic error. Here's the log of journalctl -b -1 -p 3:
