When I opened my jetson nano today, its system changed from Ubuntu to linux. What happened and what should I do? Did Jetson give up Ubuntu to linux

I won’t just ask you to check the memory for no reason.

Please refer to /etc/systemd/nvfb-early.sh on your nano. Change the default display manger to gdm3 and do re-configure.

# Read total memory size in megabyte
TOTAL_MEM=$(free --mega | awk '/^Mem:/{print $2}')
if [ $? -eq 0 ]; then
        TOTAL_MEM=$(echo "scale=1;${TOTAL_MEM}/1000" | bc)
        TOTAL_MEM=$(echo "${TOTAL_MEM}" | awk '{print int($1+0.5)}')

        # If RAM size is less than 4 GB, set default display manager as LightDM
        if [ -e "/lib/systemd/system/lightdm.service" ] &&
                [ "${TOTAL_MEM}" -lt 4 ]; then
                DEFAULT_DM=$(cat "/etc/X11/default-display-manager")
                if [ "${DEFAULT_DM}" != "/usr/sbin/lightdm" ]; then
                        echo "/usr/sbin/lightdm" > "/etc/X11/default-display-manager"
                        wait_debconf_resource
                        DEBIAN_FRONTEND=noninteractive DEBCONF_NONINTERACTIVE_SEEN=true dpkg-reconfigure lightdm
                        echo set shared/default-x-display-manager lightdm | debconf-communicate
                fi
        fi
else
        echo "ERROR: Cannot get total memory size."
fi
