What is the username and password for the TDX-X11 image?

Hi. Below you can find all the changes I have made to the local.conf file (the packages I’ve included):

IMAGE_INSTALL_append = "python3"
IMAGE_INSTALL_append = " python3-pip"
IMAGE_INSTALL_append = " python3-spidev"
IMAGE_INSTALL_append = " python3-requests"
IMAGE_INSTALL_append = " python3-smbus2"
IMAGE_INSTALL_append = " python3-gpiod"
IMAGE_INSTALL_append = " program"
IMAGE_INSTALL_append = " modemmanager"
IMAGE_INSTALL_append = " networkmanager"
IMAGE_INSTALL_append = " gtk+3 python3-pygobject cairo"
IMAGE_INSTALL_append = " matchbox-keyboard"

IMAGE_INSTALL_remove = " ofono connman connman-gnome connman-client connman-plugin-ethernet connman-plugin-loopback connman-plugin-wifi"
# To finally remove ofono
DISTRO_FEATURES_remove = " 3g"

CORE_IMAGE_EXTRA_INSTALL += " python3 python3-pip python3-smbus2 python3-spidev networkmanager"

I’ve checked that status of the xserver-nodm using the following command:

systemctl --no-pager status xserver-nodem
Unit xserver-nodem.service could not be found.

But it says that the service was not found. These are all the services that are running:

 systemctl --no-pager status

Do you have any idea what is wrong?
