When run in any other mode, vncconfig is a one-shot program used to configure or control Xvnc as appropriate. It can be used to tell Xvnc to connect or disconnect from listening viewers, and to set and retrieve Xvnc's parameters.

VNC reads the user configuration settings from the ~/.vnc/config file. Open the file and add the following: vim ~/.vnc/config session=gnome geometry=1920x1200 localhost alwaysshared The session option specifies the session you want to start, and the geometry option specifies the size of the VNC desktop. Save and close the file.
