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

Re: Screen Turning Black on Fullscreen
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.

Re: Screen Turning Black on Fullscreen
Take the VRAM to the max of 128 MB (VM Settings » Display » Screen). And since you're at it, enable 3D acceleration.00:00:02.530934 VMSVGA3dEnabled <integer> = 0x0000000000000000 (0) 00:00:02.530934 VMSVGAEnabled <integer> = 0x0000000000000001 (1) 00:00:02.530935 VMSVGAPciId <integer> = 0x0000000000000001 (1) 00:00:02.530935 VRamSize <integer> = 0x0000000001000000 (16 777 216, 16 MB)
If you still have a problem, change the Graphics Controller from VMSVGA to VBoxVGA (no S). See if that works...

Re: Screen Turning Black on Fullscreen
Did you have to switch to VBoxVGA, or the first few suggestions fixed it?

Re: [Solved] Screen Turning Black on Fullscreen
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

Re: Screen Turning Black on Fullscreen
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! lolsocratis wrote:Take the VRAM to the max of 128 MB (VM Settings » Display » Screen).
