# Parameters in /sessionstart/

In this section, we will describe all the parameters currently used by the session startup scripts. These configuration parameters reside in `/opt/thinlinc/etc/conf.d/sessionstart.hconf`.

/sessionstart/background_color

  The initial color of the background that is set early during session startup. The default color is white.

/sessionstart/background_image

  A PNG used as the initial background. The image will always be zoomed to fit each individual monitor. The default is a ThinLinc- branded image.

  An empty value will disable the background image. If no image is set, or if the image contains transparency then the color set by `/sessionstart/background_color` will shine through.

/sessionstart/keyboard_layout

  The default virtual keyboard layout used by Xvnc. The protocol is not dependent on this being configured, but some applications can misbehave if a different virtual layout is configured compared to the real keyboard layout on the client device.

  A list of possible keyboard layouts is given by this command:

      $ man /opt/thinlinc/share/man/man7/xkeyboard-config-2.7
