Internal Camera help!

Hi folks,

I need help integrating a driver for my web cam. It appears my internal web cam is not populating, and I'm not sure where to start. Any suggestions?

Re: Internal Camera help!

Welcome to the forums.  Please use BBCode tags around program output and file contents.  I may abuse my privilege and fix that for you.  wink

I wager that your webcam is a USB device rather than a PCIe device as it does not need the bandwidth.   What is the output of lsusb and of ls -l /dev/video*
?

Thank you! I will learn how to use BBCODES and I got lsusb working on terminal now!

ls -l /dev/video* returned a error on terminal.

It's embedded into the screen, it's not an external USB camera if that helps

Re: Internal Camera help!

The /dev/video* was just a shot in the dark.  If it existed then were fighting the wrong problem.  It doesn't, so the camera is indeed not being found.

I expected to see it in the USB devices sad
It looks like you have a Dell.  Is there a BIOS option to to enable/disable it?  Do you dual boot Windows?  Did you disable Windows fast start mode (not to be confused with BIOS fast boot mode)?

Edit:  What is odd is that you seem to have two fingerprint readers.

I have no idea why that is either smile

I moved directly to Arch, disabled Secure Boot, with the web cam, bluetooth, and wifi enabled on BIOS!
