x11vnc is great, remmina is great (can scale the client window, no matter the vnc server resolution it will fit on the client screen)

manpage remmina: remmina.man.txt

when the user followed the instructions here on how to setup vnc server on GNU Linux

connecting to the server with remmina might still fail with: “rfbProcessClientNormalMessage: read: Connection reset by peer”

this happens when the client vnc software has a different color map (8 bpp, 16 bpp, 24 bpp, 32 bpp) set

than the vnc server offers

run this command on server to see the settings of vnc:

xdpyinfo -display :0

hostnamectl; # tested on client
         Icon name: computer-desktop
           Chassis: desktop
  Operating System: Debian GNU/Linux 10 (buster)
            Kernel: Linux 4.19.0-13-amd64
      Architecture: x86-64

hostnamectl; # tested on server
         Icon name: computer-desktop
           Chassis: desktop
