Only a quarter of the screen showing in VirtualBox

[[e-mail]]

Only the top left quarter of my Ubuntu 22.04.1 desktop is showing on VirtualBox 6.1.30. I've installed Guest Additions CD. apt updated and restarted twice.

I've tried Xubuntu and Kubuntu 22.04 and they both work without any errors.

gnome-2048 is a 'sliding tile puzzle game' which doesn't seem appropriate looking at your screenshot and reading the bug description. I'm moving this to gnome-shell which will bring this bug report to the attention of the Desktop Team.

I can't seem to reproduce the bug in a 22.04.1 VM with guest additions installed. Not in Wayland or Xorg. Desktop resizing works.

Do you see the issue in just Xorg sessions ("Ubuntu on Xorg") or Wayland too ("Ubuntu" on the login screen)?

A guy on Reddit helped me. If I click logout I get this popup message:

xmessage
VBoxClient: Failed to register resizing support, rc=VERR_RESOURCE_BUSY
OK

then the whole screen appears and I can use the desktop. And I can also log out if I click log out again.

But when I restart the error happens all over again and I have to get the error popup before I can use the desktop.

I don't know about the xorg thing because I don't have a login screen, I just go straight to desktop.

But it's fine, I gave up on getting Gnome to work anyway because KDE is just so much more configurable and uses less screen space and is neater. I'll try Gnome again in a few years to see if it's improved. Thanks!
