OLPC has begun qualification of a new camera sensor SIV121C for the XO-1, XO-1.75 and XO-4 laptops.

Problem

The released operating system does not have a driver for the SIV121C sensor, so new laptops or old laptops with cameras replaced with the new sensor will not work with the camera. The Record activity will show a blank image.

Solution

XO-4, XO-1.75 and XO-1 only:

Upgrade to 13.2.1.

Or, on unsecure laptops, upgrade just the kernel, Start the Terminal activity and type this:

sudo yum install -y kernel

And then shutdown and reboot.

XO-1.5

The SIV121C sensor is not supported and does not work on the XO-1.5, because the motherboard provides a 48 MHz clock, and the sensor requires a maximum 27 MHz clock.
