I swapped it out for a solid black background, and, sure enough, responsiveness is now about what the RPi4 OS's responsiveness was (with the CA Neb background).

That's not not blindingly fast by any means, but it's workable. I guess that somehow Ubuntu's x11vnc vnc-server is serving up more picture quality at the expense of latency, but I can't seem to find a control to trade it off a little-I tried the obvious quality user setting, set to Auto but tried medium and low, but that did nothing for me. I guess you could say that RPi OS can handle a background and Ubuntu can't so RPi OS is a bit quicker, and I'd agree with that. Let me know if you have any further suggestions-I'm running the following to start VNC on Ubuntu: I have a raspberry pi that I do not have direct access to. Neither do I have access to the router its connected to. usr/bin/x11vnc -auth guess -forever -loop -noxdamage -repeat -rfbauth PASSWORD_FILE -rfbport 5900 -shared -display :0Īnd using the default VNC server for Raspberry Pi OS, not changing any parameters.īut, I need to change Port Forwarding, and to do that, I need to have access to a GUI. I'm using the same RealVNC VNC Viewer as my client on my Mac for both systems.

At the beginning it plays smoothly (slow motion), but later on I experience drops (fast motion) Portable Camera/Camcorder Project Kit for Raspberry Pi 3, Pi 2, B+, A+, B and A models Raspberry Pi Course Sale: 10 off today (100Mbps, CPU slow, etc) Using V4L2 and R-Pi camera I was able to set 30 fps at 352x288 and 4 fps at 1280x720, with ARM. The VNC client estimates: 'Line-speed estimate: 26121 kbits/s (RTT ~0ms)' which sounds fast to me.

Ken: Thanks for the suggestion, but at this point I'd prefer not to run xpra, but rather keep the Ubuntu windowing environment.
