I have been trying to enable the camera on my Pi using raspi-config. I am using the new 7" official touchscreen display. When I try to use the camera, I get an error message saying that the camera is not enabled. It have tried raspi-config repeatedly with reboots between passes. No luck.
raspi-config is made for a wider screen by default, but it still doesn't seem to work even when I resize the window it's running in on the 7" display. I have not had this problem when using a full size HDMI display.
