  A way to make Librealsense installation be independent of Linux versions and kernels is to set CMake to build using a libuvc bypass flag called -DFORCE.  A lot of changes were made to how Librealsense handles libuvc in its recent 2.30.0 version, so a typical CMake build command that uses the bypass should look like this;

  cmake ../ -DFORCE_RSUSB_BACKEND=true -DCMAKE_BUILD_TYPE=release -DBUILD_EXAMPLES=true -DBUILD_GRAPHICAL_EXAMPLES=true

  Further details about a successful use of this bypass command on D435i can be found in the link below:

  Thank you very much. That really solved the problem but it produced another problem with the GPU.it automatically switched to nouveau and I can't use my nvidi it gave me an error produced by the realsense package everytime I am trying to switch to the nvidia driver. What do you suggest?

  You could try adding the flag to build librealsense with CUDA support, since that requires an Nvidia GPU.

  Thank you it works.

  one more question about building rgbd-realsense-slam from the source. I am getting the following error:

  --------------------------------------------------------------------------------------------

  Could not find a package configuration file provided by "spdlog" with any
  of the following names:

  spdlogConfig.cmake
  spdlog-config.cmake

  Add the installation prefix of "spdlog" to CMAKE_PREFIX_PATH or set
  "spdlog_DIR" to a directory containing one of the above files. If "spdlog"
  provides a separate development package or SDK, be sure it has been
  installed.

  ---------------------------------------------------------------

  I tried downloading the spdlog and adding the corresponding flag but I got the same error

  I could not locate a solution to this error unfortunately.  I would recommend using SLAM based on RTAB-MAP instead, as Intel have published a setup guide for it that is specific to D435i.

  There is also an accompanying YouTube guide by Dorodnic the RealSense SDK Manager.

  The RTAB-MAP salm is compatible with ROS kinetic.
