[Solved] Full Screen Ubuntu - unresponsive

[dkardell]

When using a full screen on ubuntu 18.10, the screen does not resize and is UN-responsive.

Moving from "OSX Hosts" to "Linux Guests", because that's where I think your problem is...

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.

Uploaded the log. Again when you switch to full screen nothing is responsive (on Ubuntu Guest running on latest mac). if I switch back to desktop and then back to Virtualbox, I can restore view back to non-full screen and then resize the window and it becomes responsive again.

Let me know what else I can provide

00:00:01.003848 3DEnabled  <integer> = 0x0000000000000000 (0)
00:00:01.003852 VRamSize   <integer> = 0x0000000001000000 (16 777 216, 16 MB)

• Shut down the VM.
• Go to the VM Settings » Display » Screen.
  • Enable 3D acceleration.
  • Increase the VRAM to the max 256 MB.

So I could only increase VRAM (Video Memory) to 128. That and changing to 3D and upgrading to 6.0.4 appears to work!

Thanks!!!

I'm sorry, the "256 MB" reference was wrong on my part...
Glad you got it going, marking as [Solved].

Thanks - enabling 3D acceleration solved the problem for me on Ubuntu 16.04 LTS. This VM had been working - I can't be sure but I think the problem arose with the upgrade to VBox 6.
