5 years ago Hi @dlarue You can unload the module by completing the following steps: check if the module is loaded
$ lsmod | grep videobuf2_core if so unload the module
sudo modprobe -r uvcvideo
sudo modprobe -r videobuf2_core (imho it unwinds automatically once you release uvcvideo)
sudo modprobe -r videodevretrieved from issue #2846 After that create a script file (e.g install.sh)
! /bin/bash
echo "Script for installing the librealsense2 on Ubuntu 18.04 LTS" echo "Updating the OS..." sudo apt update sudo apt upgrade -y echo "Installing dependencies..." sudo apt install git libssl-dev libusb-1.0-0-dev pkg-config libgtk-3-dev -y

Issue Description
I need to get the T265 working on the rPi running Ubuntu 18.04 and ROS Melodic. If anything to know if it's viable. I have validated the T265 camera on my AMD64 desktop KUbuntu 18.04.3 with precompiled binaries. Before attempting to build on/for the rPi, I was building the kernel module from source on the desktop. It resulted in stopping on loading the kernel modules. Error was that it couldn't load videodev because videobuf2_core was in use, but I expect that'll be fine since the packaged binaries worked and a reboot will likely show compiled drivers loading.
The next step was to get the sample apps running. So when I went to build the SDK 2.0, it only is setup for building on Ubuntu 14.04 using a really old version of gcc.
