How To Install Microsoft Lifecam VX-3000 Driver on Ubuntu

Ubuntu 7

In this article, we will walk through the process of installing the Microsoft Lifecam VX-3000 driver on Ubuntu. This guide will be useful for those who want to use this webcam on their Ubuntu system.

Quick Answer

To install the Microsoft Lifecam VX-3000 driver on Ubuntu, first check if the driver is already included. In most cases, the webcam should work immediately upon connecting it to your computer. If you encounter compatibility issues with Skype, you can use a workaround by running a command in Terminal to preload a library that converts the webcam’s output to a format Skype can handle. If the workaround works for you, you can make it permanent by modifying the Skype menu entry.

Checking if the Driver is Already Included

Firstly, it’s important to note that the driver for the Microsoft Lifecam VX-3000 is typically included in Ubuntu by default. Therefore, in most cases, the webcam should work immediately upon connecting it to your computer.

To verify if your webcam is working, you can use the pre-installed application called “Cheese”. This tool allows you to test and use your webcam. Simply open the application and if your webcam works, you should see the video feed.

Troubleshooting Skype Compatibility

In some cases, the webcam might work in Cheese, but not in Skype. This is because the Microsoft Lifecam VX-3000 can only output JPEG compressed frames, which Skype cannot handle. However, there is a workaround for this issue.

You can start Skype from a Terminal window by running the following command:

LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so skype

Here, LD_PRELOAD is an environment variable that can be used to load a shared library before any other library (including the C runtime, libc.so). In this case, we are preloading libv4l/v4l2convert.so which is a library that converts the JPEG frames to a format that Skype can handle.

If you are on a 64-bit system, use the following command instead:

LD_PRELOAD=/usr/lib32/libv4l/v4l2convert.so skype

The path may differ depending on your Ubuntu version. For instance, on Ubuntu 11.10, the path may have changed to:

LD_PRELOAD=/usr/lib/i386-linux-gnu/libv4l/v4l2convert.so skype

And for Ubuntu 12.04 64-bit, use:

LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libv4l/v4l2convert.so skype

Making the Workaround Permanent

If the workaround works for you, you may want to make it permanent so that you don’t have to run the command every time you want to use Skype. You can do this by modifying the Skype menu entry to include the LD_PRELOAD command.

First, copy the Skype desktop file to your profile to prevent future updates from undoing your changes:

mkdir -p $HOME/.local/share/applications
cp /usr/share/applications/skype.desktop $HOME/.local/share/applications/

Then, open the copied file in a text editor and modify the “Exec” line to include the LD_PRELOAD command:

Exec=env LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so skype

Remember to use the correct path for your system. This will ensure that Skype always loads the necessary library when it starts.

Conclusion

In this article, we’ve covered how to install and troubleshoot the Microsoft Lifecam VX-3000 driver on Ubuntu. While the driver is typically included by default, there may be instances where you need to manually intervene for applications like Skype. By following the steps outlined above, you should be able to get your webcam up and running.
