Problem with running Logitech webcam working in Skype on Ubuntu 10.04 “Lucid Lynx”

May 30, 2010 17 comments

Here is a pretty simple fix that I found when using the Logitech QuickCam Communicate STX under Ubuntu 10.04 “Lucid Lynx” that may also apply to older versions of Ubuntu.

If the webcam does not show your video, the trick is to force it to use an older V4l library

Under Lucid Lynx, right click on the menus in the top corner and choose “Edit Menus”

Then go to “Internet”, select “Skype” and then “Properties” button.

You have an option of using one of the following as the Command


or for a 32-bit system

bash -c ‘export LD_PRELOAD=/usr/lib/libv4l/; skype’

or for a 64-bit system

bash -c ‘export LD_PRELOAD=/usr/lib32/libv4l/; skype’

Then close Skype and restart with the shortcut under “Applications” menu, “Internet”, “Skype”.

To test if the change worked, choose “Options” from the menu in Skype, then “Video Devices”, and then the “Test” button. You should see yourself in the test window.

To find out what camera you are using, run the following command in a terminal window…

Go to the “Applications” Menu, “Accessories”, and “Terminal”.

Type the following command and then hit Enter to see all of the USB devices connected to your PC, one of which will be the USB webcam.
