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