Looking for advice on what I suspect is a driver issue with Zorin Linux.

For a few months, I’ve had issues with suspend, where the computer will wake, but the screen remains black. This happens both when the computer suspends on its own and when I suspend it manually.

Worse, when I force reboot the computer:

1. only one of my monitors lights up
2. my keyboard is unresponsive.
3. Mouse still works.
4. Internet also dies.

Both monitors are connected to an Nvidia GTX 1070 GPU. The keyboard and mouse are connected via USB.

What I’ve tired

• I’ve used the Accessibility Keyboard (screen keyboard) to log in after a restart and revert to a previous state using Timeshift. This will get the keyboard, Internet and screen to work, but the moment I suspend, the problem returns.

• I did notice this issue started once I updated my GPU drivers to Nvidia ones (I’ve tried a couple).

I tried reverting to the Nouveau driver, but the problem returned.

I should probably note that when I orginally tried to install Zorin with Nvidia drivers, the install failed.

Advice

I’m looking for ideas on how to proceed.

At this point, I could start over completely with a fresh install of Zorin.

I could revert to the earliest Timeshift image I have, which would put me back to a fresh install.

I could abandon Zorin for another distro.

Thanks!
