Sad to say, but we are not mind readers - at least I am not. Laptop or desktop, what camera and touchscreen make and model ? Normally cameras are connected through USB (even on laptops) and almost all of them are UVC (USB Video Class) compliant. But some models have various ... quirks ... and you have to make some settings - usually in the form of parameters for the kernel modules / drivers - to make them work. Touchscreens usually are connected through USB also, but they should come up as HID (Human Interface Devices). A look at the output of 'lsusb' in a terminal is probably the quickest way to find out if the devices are getting seen and what the Kernel identifies them as.

hey Holger,
I am using Surface pro 6. I am using built in camera integrated camera

Don't have one of these, but it doesn't look too good. These two-in-one machines are highly integrated using lots of proprietary hardware. There is a project to add support to the Linux kernel for various Surface machines, and it does give installation instructions for installing the patched kernel on Ubuntu, but the camera of the Surface Pro 6 isn't currently supported.
