[Solved] Screen Turning Black on Fullscreen

Post by Yezat »

Hello

I've encountered an issue with Ubuntu 18.04 LTS in Virtualbox 6.
As soon as I enter full screen mode on my laptop screen, the screen turns black.
Full Screen does work on a second display though.

Can anyone help me?

Thank you

We need to see a complete VBox.log, from a complete VM run, where the problem occurs:
  • Start the VM from cold-boot (not from a paused or saved state) / Observe problem / Shutdown the VM (force close it if you have to).
  • With the VM completely shut down (not paused or saved), right-click on the VM in the VirtualBox Manager and select "Show Log".
  • Save only the first "VBox.log", ZIP it and attach it to your response. See the "Upload attachment" tab below the reply form.

Take the VRAM to the max of 128 MB (VM Settings » Display » Screen). And since you're at it, enable 3D acceleration.

If you still have a problem, change the Graphics Controller from VMSVGA to VBoxVGA (no S). See if that works...

Did you have to switch to VBoxVGA, or the first few suggestions fixed it?

It worked for me by following:
1. Virtualbox settings > Display > Video memory to 128 MB from 16 MB
2. Startup ubuntu virtual machine
3. If working, great! Else Ubuntu System Settings > Display > Turn the resolution to highest

Thank you so much! I have been trying to figure this out for hours now. I'm so grateful that I took the time to create an Oracle account and search for this post again, just to thank you. I was getting so frustrated! lol
