I need to troubleshoot a webcam that stopped working correctly in Ubuntu 12.04. It's always worked "out of the box" in the past so I have no idea what driver it uses.

How do I go about looking that up?

Use the following command to see all the loaded driver modules in the system.

Open terminal then type


And see if your driver is listed in the modules or not

there is also another command that list the PCI modules

1) There are 106 kernel modules listed by lsmod. How do I know which one the webcam is using? 2) I don't see any modules listed by lspci. Can you please elaborate on what I'm supposed to do with this? – ændrük Mar 27 '12 at 13:04
