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.
(the fact that I have to post this is a testament to the rock-solid nature of the OS!)
