I’m getting screen ghosting and the taskbar doesn’t show up when I use RealVNC on Windows 10.
I switched to a Windows 11 computer, but it’s the same.
I tried both USB-C and Ethernet connections, and even switched to TightVNC, but the results are still the same.

The issue you’re experiencing with screen ghosting and the taskbar not showing up when using RealVNC on Windows 10, and also on Windows 11, with both USB-C and Ethernet connections, and even after switching to TightVNC, suggests a deeper problem that may not be directly related to the VNC client or the connection method. Given the context, let’s break down the potential causes and compare them to the information provided:
Hardware and Platform: You’re using the NVIDIA Jetson Orin Nano Engineering Reference Developer Kit, which is a specific platform designed for development and testing. This platform is based on the NVIDIA Jetson Orin Nano module, which is known for its high-performance capabilities in AI and computer vision applications.
Software Environment: Your system is running Ubuntu 22.04 LTS (Jammy Jellyfish) with a Linux kernel version of 5.15.148-tegra. This is a specific software configuration that might have its own set of compatibility issues or optimizations that could affect VNC performance.
VNC Clients: You’ve tried both RealVNC and TightVNC, which are two different VNC clients. The fact that the issue persists across both clients suggests that the problem might not be with the VNC client itself but rather with how the Jetson Orin Nano handles remote desktop connections or with the network connection.
Connection Methods: You’ve used both USB-C and Ethernet connections, which rules out issues that might be specific to one type of connection (e.g., Wi-Fi vs. wired).
Comparison with Similar Issues: Looking at the provided context, there are mentions of HDMI display issues on the Jetson Orin NX and other device-tree related problems. While these issues are not directly related to VNC, they do indicate that there can be display and configuration issues with Jetson devices that might manifest in different ways.
Potential Solutions:
Update and Configuration: Ensure that your Jetson Orin Nano and the VNC server are updated to the latest versions. Sometimes, updates can resolve compatibility issues or bugs that affect performance.
Device Tree Modifications: Given the mentions of device-tree issues in the context, it might be worth exploring if any device tree modifications could help resolve the display issues you’re experiencing with VNC.
Alternative VNC Servers: Try using a different VNC server on your Jetson Orin Nano. The issue might be specific to the VNC server software you’re currently using.
Remote Desktop Protocols: Consider using alternative remote desktop protocols or software that might be more compatible with your setup.
In conclusion, the issue you’re facing seems complex and might require a combination of troubleshooting steps, including software updates, configuration adjustments, and potentially exploring alternative VNC clients or servers. The fact that the issue persists across different Windows versions and VNC clients suggests a deeper compatibility or configuration issue that will need careful diagnosis.

The issue has been resolved.
It was caused by compatibility and rendering problems.
I switched to xfce4, stopped xserver, and used NoMachine instead — now it works fine.
