- [Get started with the Qualcomm IM SDK](https://docs.qualcomm.com/bundle/publicresource/topics/80-70023-51/install-sdk.html) for
                your Qualcomm Linux 1.7 or Ubuntu Server.
- Activate SSH on your Qualcomm Linux or Ubuntu to sign in with SSH and connect to the
                target device. For instructions see:
    - [Sign in using SSH](https://docs.qualcomm.com/bundle/publicresource/topics/80-70023-254/how_to.html#use-ssh) for Qualcomm
                        Linux
    - [Sign in using SSH](https://docs.qualcomm.com/bundle/publicresource/topics/80-90441-1/Use_Ubuntu_on_RB3_Gen2_3.html#sign-in-to-the-rb3-gen-2-console-using-ssh) for Ubuntu
                        Server

Note: If SSH is already set up and Wi-Fi is connected,
                    skip this step.
- Use the HDMI port to connect the display to the device. For instructions, see [Set up HDMI display](https://docs.qualcomm.com/bundle/publicresource/topics/80-70023-18/samples.html).
- Sign in to the target device using SSH.
- In the terminal of the target device, run the following commands from the SSH shell
                of the target device to activate the display on the host computer:
    - For
                        Linux:

            export XDG_RUNTIME_DIR=/dev/socket/weston && export WAYLAND_DISPLAY=wayland-1Copy to clipboard
    - For Ubuntu Server:

            export XDG_RUNTIME_DIR=/run/user/$(id -u ubuntu)/ && export WAYLAND_DISPLAY=wayland-1 Copy to clipboard
- Connect the speaker to activate the audio on the target device. For instructions,
                see [Set up audio hardware](https://docs.qualcomm.com/bundle/publicresource/topics/80-70023-16/enable-audio.html).
If you face
                    issues in recording the audio, run the following command in the terminal of the
                    target
                    device:

        pactl set-default-source pal_source_speaker_micCopy to clipboard
- If you face issues with the camera or display, see [Camera troubleshooting](https://docs.qualcomm.com/bundle/publicresource/topics/80-70023-17/troubleshooting.html) and [Display troubleshooting](https://docs.qualcomm.com/bundle/publicresource/topics/80-70023-18/debug.html).
