Issues with VirtualBox on Ubuntu 12.10

Problem:

Are you having issues starting virtual box after installing updates?  Annoying isn't it?  Errors like the following:

Kernel driver not installed (rc=-1908)The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing'/etc/init.d/vboxdrv setup'as root. If it is available in your distribution, you should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary.

Maybe you have an issue with the networking card when operating in bridged mode and get an error similar to the following (note might also say HostInterfaceNetworking-wlan0) :

Failed to open/create the internal network 'HostInterfaceNetworking-eth0' (VERR_PERMISSION_DENIED). Failed to attach the network LUN (VERR_PERMISSION_DENIED)

Solution:

VirtualBox recommends you run sudo /etc/init.d/vboxdrv setup but unfortunately this is not available on most Ubuntu installations.  I would recommend running the following:

sudo apt-get install linux-headers-$(uname -r)
sudo apt-get --reinstall install virtualbox virtualbox-dkms 
sudo modprobe vboxdrv
sudo modprobe vboxnetflt
sudo modprobe vboxnetadp

Good luck!

How to set Full Pixel on a Sony KDL-55EX720

I recently got a Monoprice mini DisplayPort to HMDI w/Audio adapter for my Dell XPS 13 running Ubuntu 12.10 Quantal Quetzal.  I am happy to report that audio over HDMI works just fine out of the box with no software to install as long as the device receiving the signal supports audio over HDMI such as my Sony KDL-55EX720. Unfortunately, the picture was overscanned (cut off on the edges).

In order to fix this, you have to set your Display Area to full pixel.  Unfortunately I could not find out for the life of me how to get to this option on my TV.  Fortunately, I ended up stumbling onto it.

1. Hit the HOME button on your Sony remote.
2. Scroll to the input connection that your computer or other overscanned device is on (mine is HDMI 3).
3. Hit the RIGHT arrow on the circle pad until you get to the options menu (i-Manual, Preferences, Sound, Picture and Display, etc)
4. Select Picture & Display by hitting the Select button (center of circle pad)
5. Scroll down to Screen and hit Select
6. Scroll down to Auto Display Area and hit Select and turn that option Off.
7. Scroll down to Display Area and set this to Full Pixel
8. Hit RETURN until you exit the menu.  Your display should now full fill the screen.

If you have issues with getting the picture to show up at all, then open you Display control panel and click Detect Displays.
