Issue with failed to get display change request

I get this when I start the workstation:

VBoxClient: Failed to get display change request, rc=VERR_INVALID_HANDLE

VBoxClient: Failure waiting for event, rc=VERR_INVALID_HANDLE

It starts in a small window and I cannot change the resolution.

Virtualbox 6.1.22

I believe I’m using Whonix-XFCE-15.0.1.7.2, but I also had the problem with an earlier version, which prompted me to reinstall. This fixed the problem, for a while, now it is back.

What is the reason for this? Rebooting doesn’t help.

First, see here for general VirtualBox troubleshooting and a lot of known issues:

But to your point, this might be useful:

I run void linux as guest in virtualbox and it worked for me without problems until today. Now my guest desktop gets spammed with notifications like:

VBoxClient: Failure waiting for event, rc=VERR_INVALID_HANDLE
VBoxClient: Failed to get display change request, rc=VERR_INVALID_HANDLE
VBoxClient: VbgIR3InitUser failed: VERR_ACCESS_DENIED

I suppose this has to do with a kernel update from yesterday. Maybe this is somehow related to your problem?

Later they say:

I could solve my virtualbox guest problems by installing linux-headers and virtualbox-ose-guest-dkms with xbps. The latter really fixed everything. Maybe in your case you could try installing virtualbox-ose-dkms. Hope this helps if you haven’t found a solution already.

Since a few known problems relate to not having linux-headers installed, maybe it is related.
