I've been using Zorin OS for the past little while as my primary OS. Unfortunately around three times a day my system will freeze (everything, can't alt tab, can't open a terminal) and after around a minute will crash and reboot. So far I've been lucky and haven't lost anything but I also haven't found the cause.
I suspect that nvidia is involved somehow as I first encountered the crash while changing display scaling. Beyond that I am not sure. I think that my integrated card and my 1070 are causing issues with each other. Should I try disabling my integrated graphics?
The crash has also occurred at seemingly random times, but at the time I was doing some heavy lifting resizing and formatting things in gparted. (and moving things from ntfs to ext4)
So those are my ideas, either a disk issue or an nvidia issue. Thoughts?
