How to enable or disable camera in Ubuntu Linux

In Linux, you must gain root access before you can do anything that would modify the system, if you have administrator access, you can disable and enable cameras in your ubuntu Linux system.

As of the date of this writing, there are no settings in Ubuntu Settings App to allow either disabling or enabling attached camera. If we do find a setting eventually, the most effective way will be through the use of an administrator’s terminal console.

The latest drivers for both cameras and webcams available on Ubuntu are UVC (USBVideo Class) compliant, which means they work well with the generic uvcvideo kernel driver module.

To list the uvcvideo kernel driver module, run the command below:

sudo lsmod | grep 'uvcvideo'

If nothing returns, then it seems Ubuntu could not identify the device or does not have the correct driver. However, if the camera is seen and loaded drivers are present, you should see similar messages as listed below:

uvcvideo              106496  0
videobuf2_vmalloc      20480  1 uvcvideo
videobuf2_v4l2         32768  1 uvcvideo
videobuf2_common       77824  4 videobuf2_vmalloc,videobuf2_v4l2,uvcvideo,videobuf2_memops
videodev              258048  3 videobuf2_v4l2,uvcvideo,videobuf2_common
mc                     65536  4 videodev,videobuf2_v4l2,uvcvideo,videobuf2_common

If you do not receive a similar outcome, it may also mean that another driver is installed for your camera. Check these sites here and here for further information about drivers.

Remove Camera Drivers From Ubuntu Linux

To remove Run the commands below to remove the camera driver as show below:

Replace uvcvideo driver name with other names of drivers that is installed on your system.

If the camera is in used during the removal process, you will get a error similar like below:

modprobe: FATAL: Module uvcvideo is in use.

To resolve this error, close the app that are currently using the camera, then again run the same command above to remove or disable the camera.

The job is not done yet, the command above disable the camera drive but a simple reboot will reinstall it again in your system. To prevent this, run the command below to add the driver to the block list configuration file located at ‘/etc/modprobe.d/blacklist.conf‘ as show below:

echo 'blacklist uvcvideo' | sudo tee -a /etc/modprobe.d/blacklist.conf

All drivers that are added to block list configuration file are blocked permanently. After that, applications of your systems will not be able to use your camera.
