Run the server with: export XSPICE_PORT=5900 X -noreset -config spiceqxl.xorg.conf :3.0 Or: Xspice --config spiceqxl.xorg.conf --password mypass --port 5900 :3.0 (you can use also --disable-ticketing to disable authentication!) Use a spice client (like spicy) to connect. Run X clients as usual by setting DISPLAY=:3.0
