Bug Description

I have been using Ubuntu 16.04 betas in Virtual Box for two months now and all was working fine. But beginning two days ago, I am no longer able to use a resolution higher than 1024x768. virtualbox-guest-x11 is installed. After login, the following error message is shown on my desktop:

VBoxCliend DND Failed to connect to the VirtualBox kernel service rc=VERR_ACCESS_DENIED

Host: OS X, VirtualBox 5.0.18, 64bit
Guest: Ubuntu 16.04 latest daily (2016-04-17) plus all updates as of 2016-04-19

dmesg does not show any virtualbox related errors:

Hi, can you please run
dpkg-reconfigure virtualbox-guest-dkms?

thanks

it turned out virtual-box-guest-dkms was not installed at all (I formerly did apt install virtualbox-guest-x11 to install the guest utilities; are there any dependencies missing?)

after

apt install virtual-box-guest-dkms

I got an error message (in the terminal):

module 5.0.16_ubuntu for vboxvideo.ko is not newer than what is already found in kernel 4.4.0-18-generic. You may override by specifiying --force.

---

I now tried

dpkg-reconfigure virtualbox-guest-dkms --force

same error again; I don't know for which command I should use --force

---

I finally tried:

dkms build -m virtualbox-guest -v 5.0.16
Module virtualbox-guest/5.0.16 already built for kernel 4.4.0-18-generic/4

dkms install -m virtualbox-guest -v 5.0.16
Module virtualbox-guest/5.0.16 already installed on kernel 4.4.0-18-generic/x86_64

---

after a reboot, the problem persists (as expected)

indeed, because the module provided by the kernel itself is *bad*.

Please try to remove the vbox* from /lib/modules, and do again the dpkg-reconfigure.
after a reboot everything is fine.
