I'm running Backtrack 4 R1 in Virtual Box. When I try to upgrade to the new kernel, my guest additions are disabled. I tried the following fix, posted in another thread, and it did not work:

Code:

quit
apt-get update
apt-get upgrade
apt-get install dkms
Install Vbox Guest Additions..

Code:
mount /dev/hdX /mnt/cdrom
cd /mnt/cdrom
./VBoxLinuxAdditions-x86.run
reboot
Then check if vbox modules are loaded on boot and vbox guest services are running...

Code:
dmesg |grep vbox
/etc/init.d/vboxadd status && /etc/init.d/vboxadd-service status
Check /var/log/Xorg.0.log in order to verify vbox xorg modules are loaded successfully. Here a xorg.conf example :
Code:
Section "InputDevice"
        Identifier      "VirtualBox Mouse"
        Driver          "vboxmouse"
        Option          "CorePointer"
EndSection

Section "Device"
        Identifier      "VirtualBox Video Card"
        Driver          "vboxvideo"
        BusID           "PCI:0:2:0"
EndSection

Section "Monitor"
        Identifier      "Configured Monitor"
        Option          "DPMS"
EndSection

Section "Screen"
        Identifier      "Default Screen"
        Monitor         "Configured Monitor"
        Device          "VirtualBox Video Card"
        DefaultDepth    24
        SubSection      "Display"
          Depth         24
          Modes         "1152x864" "1024x768" "800x600" "640x480"
        EndSubSection
EndSection
And finally ensure you have /usr/bin/VBoxClient-all added in your .xinitrc
I did this and it still said the guest additions could not start.

Is there a solution for this?
