Struggle with startup with stretch robot

Hi Jason,
I am currently experiencing a connection issue between the ML computer and the robot computer, even though I have verified the network and confirmed that it is functioning properly. When I attempt to connect via RustDesk, I receive the following message.

Hi @Mallak_Alqaisi,

Could you please try the following steps:

  1. First, run these commands in a terminal on the robot:

    sudo usermod -aG render $USER
sudo usermod -aG video $USER

These ensure your user has the correct permissions for graphics and camera access.

  1. After running them, please log out and log back in (or reboot the robot) so the changes take effect.

  2. Then, restart RustDesk:

    pkill rustdesk
rustdesk

  3. Once it’s back up, try connecting again a few times. We’ve seen cases where it takes a couple of attempts for the connection to go through.

  4. Also, could you confirm if you have a dummy HDMI plug (display emulator) connected to the robot?
    This can be important, as some systems require an active display output for remote desktop tools like RustDesk to work properly.

If you don’t have one connected, that could be contributing to the issue.

Let me know how it goes and we’ll take it from there!
