I want to use vino-server for VNC with no monitor connected on Jetson Orin Developer Kit - Jetpack 5.0.1 DP. When I connect with VNC Viewer, only the splash screen is shown until I plug the DisplayPort until the monitor, then desktop then shows and is interactive but when I disconnect the DisplayPort, the vnc becomes unresponsive (mouse moves but nothing seems to be interacting).
I tried configuring the vnc/screen-sharing according to this. I tried using both ways (one at a time) for step 1 (autostart and symlink).
I also tried turning on Screen Sharing in Gnome setting page.
I also tried editing the /etc/X11/xorg.conf to add in a Screen section according to README-vnc.txt. Which didn’t work also.
I then tried adding in Monitor section into /etc/X11/xorg.conf. Also still didn’t work.
I also tried installing xserver-xorg-video-dummy then adding a ‘dummy’ Device and change the links in Screen section. Still didn’t work.
On previous Jetsons like Jetson AGX Xavier Dev Kit and Jetson Nano Dev Kit, I was able to use VNC without monitor by just following the instruction on the VNC set up page then adding Screen section to /etc/X11/xorg.conf according to the README-vnc.txt.
I also tried reflashing and reconfiguring the Jetson again. It oddly works only on first installation of xserver-xorg-video-dummy, the desktop became interactive, but after a reboot, it came back to ‘stuck’ at splash screen (and other symptoms as described above). I tried both removing and purging the xserver-xorg-video-dummy package and reinstall but can’t make it work again until first installation of xserver-xorg-video-dummy after another reflash.
