Please check the status of your gdm and gnome-remote-desktop services. If they are inactive you can start the desktop-related services with systemctl start gdm gnome-remote-desktop cups cups-browsed
how to check status of those you mentioned?
sudo systemctl status gmd
sudo systemctl status gnome-remote-desktop
sudo systemctl status gmd
sudo systemctl status gnome-remote-desktop
#!/bin/sh
# Interactive mode switcher for NVIDIA DGX OS (POSIX-compliant)
require_root() {
if [ "$(id -u)" != "0" ]; then
echo "This script must be run as root." >&2
exit 1
fi
}
switch_to_text_mode() {
echo "→ Stopping GDM..."
systemctl stop gdm
echo "→ Setting default target to multi-user.target..."
systemctl set-default multi-user.target
echo "✅ Switched to text mode. Reboot if needed."
}
restore_gui_mode() {
echo "→ Setting default target to graphical.target..."
systemctl set-default graphical.target
echo "→ Adding gdm.service to graphical.target wants..."
systemctl add-wants graphical.target gdm.service
echo "→ Starting GDM..."
systemctl start gdm
echo "→ Restarting nvidia-persistenced..."
systemctl restart nvidia-persistenced
echo "✅ GUI mode restored. You should see the login screen shortly."
}
print_menu() {

getting this @aniculescu
@Sanyam0605 try systemctl status gdm.service and not gmd.serviceJust a typo.
output:
gdm.service - GNOME DISPLAY MANAGER
loaded: loaded (/usr/lib/systemd/system/gdm.service; static)
Active: inactive (dead)
Your system is running but your GUI needs some fixing!
Check if the nvidia driver is loaded with sudo lsmod | grep nvidia
If the driver is loaded try changing runlevels and watch log output for issues:
sudo systemctl isolate multi-user.target
sudo systemctl isolate graphical.target
The fist command will change runlevel to non-GUI, and the second back to desktop.
If the GUI doesn’t start check the logs:
journalctl -b for current boot
journalctl -b -1 for previous boot
nope nvidia is not loading, even i write nivida-smi its not showing nvidia, driver not loaded is coming
see if u can help here @aniculescu or other people in Nvidia support team, would much appreciate!
would really appreciate the help from anyone
What about starting the service + try to system update (sudo apt update;sudo apt full-upgrade)
systemctl start gdm.service
Please follow my original guidance and try to activate your desktop related services. Doing a system update as @dobs mentioned is also not a bad idea
Commands to run:
sudo apt update
sudo apt dist-upgrade
sudo fwupdmgr refresh
sudo fwupdmgr upgrade
sudo reboot
This will reboot your Spark.
Afterwards, if you still don’t have GUI, run
systemctl start gdm gnome-remote-desktop cups cups-browsed
GUI didn’t start, then i ran systemctl commands this came:
Failed to start gdm.service → interactive authentication required
Failed to start gnome-remote-desktop.service → interactive auth required
and same for others
Please run the last command with sudo privileges
sudo systemctl start gdm gnome-remote-desktop cups cups-browsed
This certainly seems like an issue with your driver installation? The gnome-extensions you installed may not be compatible. Which extensions did you try to install? Exact commands would be helpful.
- You can try the update process to see if it fixes your packages
sudo apt update
sudo apt dist-upgrade
- Uninstall your gnome-extensions
- Or if none of the above work, reimage your system and start with a fresh slate System Recovery — DGX Spark User Guide
thank u so so so much!! FInally worked, via reimaging from clean slate!!
