Hi -
I've been running Zorin OS Pro since 2019. First 15 and now 16. (NUCi5BEH with 32 GB RAM and dual-booting with Ubuntu 20.04)
Over the last year, I've been plagued with random reboots and freezes. The reboots are self explanatory, the freezes result in the NUC lights showing that the PC is operational, but the monitor never comes out of sleep.
I do not have any of the same issues when I'm in Ubuntu.
If this were a Windows PC, I'd be able to troubleshoot it. However, I have had zero issues in my 5+ years of using a *nix distro and consequently don't know where to start to diagose the issue.
Any suggestions?
(the fact that I have to post this is a testament to the rock-solid nature of the OS!)
It sets the Autonomous Power State Transition to 5500 microseconds, allowing more time for the NVME drive to switch between power save states based on the rules configured in the driver (Or kernel).
While I was reading your post, that is exactly what I thought. We had a big update yesterday, and then we had another update today. So the setting could have easily been reverted in the update.
The rebooting / black screen happens in spurts. I'm assuming I have not run xset -dpms every time I've received an update, but I'm also not certain if I should need to after every update.
My current tests involve Bluetooth status. Anecdotal evidence suggests that BT is always on when the system reboots/freezes, but I have not paid close enough attention up to this point.
In the interim, anything else I can do? I was having the same problem with V15 prior to wiping and installing 16.
This is probably the source of your troubles. Iris.
Ubuntu did provide a patch that is in the (now) 5.10 kernel. I recommend trying this:
sudo apt install linux-oem-20.04
Reboot and be sure to boot into Advanced Options for Zorin by tapping the esc key or left shift key at boot. Arrow key down to zorin on 5.10.0-1051
Test that kernel thoroughly and if it works, then remove the 5.11 kernel.
Zorin lite freeze & reboot, and become unresponsive till forcefully reboot 4 times.
Please provide solutions, i want to shift to zorin but this issue don't have any solution. Required your suggestion to resolve this.
