I am running Ubuntu 18.04 on a carbon X1 which has an integrated IR camera, and an integrated ordinary webcam.

However, devices such as Skype and Chrome have mysteriously only started recognizing the IR camera. They have previously successfully found the regular webcam, but on latest reboot the webcam is not even selectable in these applications.

I understand from here that there are tools for identifying the names of my multiple camera peripherals.

What are the command line tools for restarting the webcam/resetting if some other application is holding on to it? How can I force Cheese/skype/chromium to acknowledge the normal camera exists?

(Additionally, can I make the machine completely ignore the IR Camera? It is essentially never what I want, but seems to be an Ubuntu default.)

The script presented here worked for me. It changes the device name of the IR camera and creates a symlink in its place that points to the standard camera. I added it to my crontab as a @reboot, and it works like a charm.

I had the same problem and disabled the IR camera by detaching the driver at startup from the usb device with usb_modeswitch. Also my solution uses the vendor id and product id, so it doesn't accidentally touch anything else if the system configuration changes.

My solution is here: How do I change the default webcam?
