How do I get the webcam working on a Dell Vostro 3460?

Question

The webcam is properly detected on Ubuntu 12.10, but I cannot make it work with Google Talk 3.2.4... No problem with Skype though.

xinput shows a Laptop_Integrated_Webcam_E4HD.

Make sure you have the Google talk plugin installed

For 32-bit Ubuntu try:

sudo apt-get install libv4l-0
sudo mv /opt/google/talkplugin/GoogleTalkPlugin /opt/google/talkplugin/GoogleTalkPlugin.real
echo '#!/bin/sh' | sudo tee /opt/google/talkplugin/GoogleTalkPlugin
echo "LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so /opt/google/talkplugin/GoogleTalkPlugin.real" | sudo tee -a /opt/google/talkplugin/GoogleTalkPlugin
sudo chmod +x /opt/google/talkplugin/GoogleTalkPlugin

For 64-bit Ubuntu try:

sudo apt-get install lib32v4l-0
sudo mv /opt/google/talkplugin/GoogleTalkPlugin /opt/google/talkplugin/GoogleTalkPlugin.real
echo '#!/bin/sh' | sudo tee /opt/google/talkplugin/GoogleTalkPlugin
echo "LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so /opt/google/talkplugin/GoogleTalkPlugin.real" | sudo tee -a /opt/google/talkplugin/GoogleTalkPlugin
sudo chmod +x /opt/google/talkplugin/GoogleTalkPlugin

Repeat when you install a new version of the Google Talk plugin
