Random freezes which require hard restart

Problem summary / context:
I use ZorinOS daily - and love it!

However, I'll get intermittent freezes (maybe once or twice a week) which are a little frustrating. I get them both on my work box (the one below,) and one at home which has a similar setup.

I use the super/windows key exclusively to search for/open apps, as well as Super+L to bring up the lock screen. It seems like one of those two actions has usually been used recently when the OS freezes.

I keep the system up to date, never waiting more than 4-5 days after a kernel update, security update, etc comes out before installing

Aside from the normal "help", I do have two questions:
1) Are there any log files which might be helpful in tracking down problem children after a freeze happens and I restart?
2) I recently figured out that Ctrl+Alt+1 will bring the OS into a GUI-less mode. If that still works when the system is frozen, any suggestions for commands I could run to help chase down the problem?


System information:

The one below powers two monitors (4k + 3440x1440), and another desktop I use at home only has one (4k) monitor - both experience the freeze issue - so I don't think it's related to my dual monitor setup.

OS Version: ZorinOS 12.4 Ultimate
Kernel: Linux version 4.15.0-42-generic

Custom built box by System76. Their default Pop! OS is okay..but I like Zorin better :)
Specs:

Motherboard: Gigabyte X299 AORUS Gaming 3-CF
Processor: Intel i7-7800X @ 3.50GHz
Video Card: GeForce GTX 1050 Ti
RAM: 32GB of Ballistix Sport @ 2666Mhz

Hard Drive partitioning:
Code:
sudo fdisk -l
...
Device         Boot     Start       End   Sectors   Size Id Type
/dev/nvme0n1p1 *         2048 910280703 910278656 434.1G 83 Linux

I have not overclocked the CPU or changed the RAM voltage at all - everything is stock.

ZorinOS 12.4 is the only OS installed.

I use Gnome Tweak Tool with the following settings:
  • Theme (GTK+ and icons): ZorinBlue-Light
  • Cursor: Adwaita (default)
  • Extensions: [Zorin Dash, Zorin Menu, Zorin Panel, Zorin Tray]

Thanks in advance, for any help/advice you can give!

See if installing the nVidia driver quoted at the bottom of this thread helps:

I'm currently using the 384.130 NVIDIA driver -- do you think it's a possibility they fixed and then broke it again?

edit - I did find this as well based on Googling around your link: https://bugs.launchpad.net/ubuntu/+sour ... ug/1731768 - will try to duplicate his fix next time it happens, to confirm whether or not it's a graphics driver issue.

Will update this thread with the results when I try that.
