Kali 1.0.4 VirtualBox Guest Additions and Resolutions

I installed Kali 1.0.4 64bit on VirtualBox.  After updating it, I installed Guest Additions to get custom resolutions and better mouse support.  However, I was only able to get various 4:3 ratio resolutions, and definitely not custom sizes.

The solution is in this post.  What I needed to do was to uninstall Guest Additions, then install three packages using apt-get: dkms build-essential linux-headers-amd64.

The command was:
root@kali-vbox:~# apt-get install dkms build-essential linux-headers-amd64

After that, I reinstalled Guest Additions and rebooted.  I was able to use any resolution window after that using the normal command:
root@kali-vbox:/media/cdrom# sh ./VBoxLinuxAdditions.run
