Hello @socratis

It took me a long time to get back to this thread. Remembering, I recreated a VM and, finally, it started with 3D acceleration successfully. And I did not even have to downgrade NVIDIA drivers.

It remains to know why this VM does not open on two monitors, as I usually work. Could you help me with that? I'll send you the attached LOG.

Thank you so much again.

I see the two screens for your guest. Maybe you should configure the 2nd screen from within your guest.

I thought that we already discussed this...


PS. For future reference, you should completely shut down the VM before grabbing the VBox.log.

I've attached a new log so you can check it out if it's not upsetting. As you can see, this time I left 3D enabled. This is no longer a problem for me. Now all that is left is to make the two monitors appear.

Thank you again.

The complete shut down was for future reference. I saw whatever I wanted to see from the incomplete log.

And that was that you do have 2 virtual screens. The only thing now is to configure them from within your guest. Could you tell me the name in the title bar of your VM?

The VM title bar is: "Mint_x64_RW [Executando] - Oracle VM VirtualBox: 1".

You see that ": 1" part? That means Window/Screen1. There is a Window/Screen2 somewhere, perhaps behind your 1st screen?

Go to the host's "View" menu and try to see what's there. Do you have a "Virtual Screen 1" and a "Virtual Screen 2"?

You killed the charade. Look at the attached image.

I was taken to error, because whenever I chose 2 monitors, both automatically opened. But this time the second monitor was disabled I do not know why.

Good, thank goodness. Everything is OK now. I would like to thank you for all the help since the beginning of this thread. Big hug.

Finally! ;)
I split the related posts from the original thread. I should have done that long ago. Anyway, marking as [Resolved].
