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.
I believe I’m using Whonix-XFCE-188.8.131.52.2, 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.
