Don’t have a display and want to use your DGX SPARK In its native Desktop Environment? I put together this repo ( GitHub - eelbaz/dgx-spark-headless-sunshine: Headless remote desktop setup for NVIDIA DGX SPARK using Sunshine streaming ) which provides an Automated setup for headless native remote desktop streaming for the NVIDIA DGX SPARK system using Sunshine and a moonshine client. With it, you extend use your DGX usage beyond ssh/cli to leverage Spark’s native desktop environment remotely.
This worked flawlessly, lets me work from halfway around the world on the native Spark GUI. Thanks for this.
does this script assume a monitor? I wasn’t successful getting the script to work. I did this with the Oct19th version and manually modified to use a different release url that functioned.
generally sunshine was unable to get access to the display.
LOL, wish I saw this about an hour ago. I just used gpt-oss:120b on my spark to do this for me from scratch, had to export a .bin from my monitor to use.
Have you been able to get anything over 60hz at 3840 x 2160? The best I could do is 1440p @ 120Hz
It stated ‘The GB10’s internal display controller has a 165 MHz maximum pixel clock limitation (we saw this earlier), which can’t handle the bandwidth required for 4K from your M32U EDID’
You’re the GOAT!
I’m on a mac – When the PIN was failing, I had to toggle moonlight ON > OFF > ON in the “local network” settings
Thanks for this, not only do I have remote access but for some reason the HDMI connection started working as well. Before that just a black screen.
I tried all kind of configs but I could not go beyond 1600x900. Did anyBody found a way to increase resolution? If so… which one did you manage to ? I might be too bold trying 2560x1440…
you have to modify the headless-xrandr.desktop file in $HOME/.config/autostart/
You can set the 1600x900 parameter. Instead, I used mine to use nvidia-settings via a script.
Exec=/bin/sh -c '/home/dgx/res-modes/2192x1565.sh; sleep 5; if ! pgrep -x sunshine >/dev/null 2>&1; then DISPLAY=:0 XAUTHORITY=/run/user/1001/gdm/Xauthority XDG_RUNTIME_DIR=/run/user/1001 /usr/bin/sunshine & fi'
2192x1565.sh:
/bin/sh -c 'nvidia-settings -a CurrentMetaMode="HDMI-0: nvidia-auto-select { ViewPortIn=2192x1565, ViewPortOut=2192x1565+0+0 }"'
Note: the user ids and other parameters might be different, just modify it to your system requirements.

Thank you very much. What I ended up doing is:
a) Adding Modevalidation in xorg.conf to avoid nvidia testing if the mode is correct for a monitor that I don’t have…
Section “Device”
Identifier “Device0”
Driver “nvidia”
VendorName “NVIDIA Corporation”
BoardName “NVIDIA GB10”
Option “AllowEmptyInitialConfiguration” “True”
Option “VirtualHeads” “1”
Option “ConnectedMonitor” “DFP-0”
Option “Coolbits” “28”
Option “ModeValidation” “AllowNonEdidModes, NoMaxPClkCheck, NoEdidMaxPClkCheck, NoHorizSyncCheck, NoVertRefreshCheck”
EndSection
Also I modified the screen section:
Section “Screen”
Identifier “Screen0”
Device “Device0”
Monitor “Monitor0”
DefaultDepth 24
Option “MetaModes” “HDMI-0: 2560x1440 +0+0”
SubSection “Display”
Virtual 2560 1440
Depth 24
EndSubSection
EndSection
b) I created a new mode (don’t know if i need it or if it helped, as I was doing lots of testing)
cvt -r 2560 1400 60
xrandr --newmode “2560x1400R” 234.75 2560 2608 2640 2720 1400 1403 1413 1440 +hsync -vsync
xrandr --addmode HDMI-0 “2560x1400R”
As I say I would bet this step is not needed, but I cannot know for certain.
c) I changed headless-xrandr.desktop for it to create a bigger virtual display (I guess it is that that it does)
[Desktop Entry]
Type=Application
Exec=/bin/sh -c ‘/usr/bin/xrandr --output HDMI-0 --mode 2560x1400; sleep 5; if ! pgrep -x sunshine >/dev/null 2>&1; then DISPLAY=:0 XAUTHORITY=/run/user/1000/gdm/Xauthority XDG_RUNTIME_DIR=/run/user/1000 /usr/bin/sunshine & fi’
Hidden=false
NoDisplay=false
X-GNOME-Autostart-enabled=true
Name=Headless Display Mode
With this, it worked.

Nice, I haven’t had much success with adding a new mode using xrandr, that’s why I just ended up using nvidia-settings but whew that looks like a lot of work.
