# Prerequisites

- [Get started with the Qualcomm IM SDK](https://docs.qualcomm.com/bundle/publicresource/topics/80-70029-51/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/80-70029-254/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/80-70029-18/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-1
            Copy 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/80-70029-16/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_mic
        Copy to clipboard
- If you face issues with the camera or display, see [Camera troubleshooting](https://docs.qualcomm.com/bundle/publicresource/topics/80-70029-17/troubleshooting.html) and [Display troubleshooting](https://docs.qualcomm.com/bundle/publicresource/topics/80-70029-18/debug.html).
