We recently setup a new installation of Pop OS (Version 21.10), and were in the middle of setting up remote desktop sharing with VNC when we ran into a snag. We were prompted by this error:
Error Message: RFB protocol error: unknown rect encoding 10794
VNC is great and we’ve been using it for years to remote into our machines, but this was a first. The solution, as it turns out, is pretty straight forward. We use RealVNC so you may have to look around in whatever client you use for a similar setting / option.
Start by creating a new New Connection in RealVNC
Enter the target machine’s IP in the VNC Server field and click on Options.
Select the High setting option from the Picture Quality setting.
That’s it, try connecting to your server and it should work just fine.
