Overview

The display module can manage Xvfb (X Virtual Framebuffer) and x11vnc for remote displays.

The base class, display, can be used to manage both xvfb and x11vnc together.

xvfb and x11vnc can be managed individually using their own classes if desired.

Additionally, a profile.d helper script can be managed that exports the DISPLAY environment variable.

Setup

What display affects

The display module can manage the following:

  • xvfb package
  • xvfb service
  • x11vnc package
  • x11vnc service

Usage

To manage xvfb and x11vnc with default parameters:

include ::display

Custom display, resolution and color depth:

class { 'display':
  display => 99,   # default is 0
  width   => 1024, # default is 1280
  height  => 768,  # default is 800
  color   => 24,   # default is "24+32" (i.e. 32-bit)
}

Running as a custom user (both xvfb and x11vnc):

class { 'display':
  runuser => 'xvfbservice',
}

Only manage xvfb (e.g. not x11vnc) and specify a custom user and fbdir:

class { 'display::xvfb':
  runuser => 'xvfbuser',
  fbdir   => '/var/tmp/xvfb',
}

Only manage x11vnc:

class { 'display::x11vnc':
  display => 3,
  runuser => 'x11user',
}

Reference

Classes

  • display: Main class, includes all other classes (wrapper)
  • display::xvfb: Manages xvfb
  • display::x11vnc: Manages x11vnc

Class: display

display

X display to use. Default is 0

width

Screen width to use. Default is 1280

height

Screen height to use. Default is 800

color

Screen color depth to use. Default is '24+32' (32-bit)

runuser

User to run xvfb as. Default is 'root'

fbdir

Directory in which the memory mapped files containing the framebuffer memory should be created. Defaults to '/tmp'

xvfb_package

Package name for installing xvfb. Defaults to xorg-x11-servers-Xvfb on RedHat systems and xvfb on Debian systems.

xvfb_service

Name of the xvfb service. This class will create an init script with this name and manage a service by this name. Defaults to xvfb

xvfb_bin

Absolute path to the xvfb executable. Defaults to /usr/bin/xvfb on RedHat and Debian systems and /usr/local/bin/Xvfb on FreeBSD.

xvfb_custom_args

Custom arguments to use for starting xvfb. If this parameter is defined, the display, width, height, color, and fbdir parameter values will not be used for starting the xvfb service via the init script - that's left up to the user. Optional. Defaults to undefined.

x11vnc_package

Package name for installing x11vnc. Defaults to x11vnc on RedHat and Debian systems.

x11vnc_service

Name of the x11vnc service. This class will create an init script with this name and manage a service with this name. Defaults to x11vnc

x11vnc_bin

Absolute path to the x11vnc executable. Defaults to /usr/bin/x11vnc on RedHat and Debian systems and /usr/local/bin/x11vnc on FreeBSD.

x11vnc_custom_args

Custom arguments to use for starting x11vnc. If this parameter is defined, the display parameter is unused for starting x11vnc - that's left up to the user. Optional. Defaults to undefined.

display_env

Boolean. Provide a profile.d script to export the DISPLAY variable. Defaults to true.

NOTE: This parameter and the display::env class is being deprecated and will soon be removed.

display_env_path

Absolute path to place a profile.d script that exports the DISPLAY variable. Defaults to /etc/profile.d/vagrant_display.sh This is only effective if 'profiled' is true.

NOTE: This parameter and the display::env class is being deprecated and will soon be removed.

Class: display::xvfb

display

X display to use. Default is 0

width

Screen width to use. Default is 1280

height

Screen height to use. Default is 800

color

Screen color depth to use. Default is '24+32' (32-bit)

runuser

User to run xvfb as. Default is 'root'

fbdir

Directory in which the memory mapped files containing the framebuffer memory should be created. Defaults to '/tmp'

package

Package name for installing xvfb. Defaults to xorg-x11-servers-Xvfb on RedHat systems and xvfb on Debian systems.

custom_args

Custom arguments to use for starting xvfb. If this parameter is defined, the display, width, height, color, and fbdir parameter values will not be used for starting the xvfb service via the init script - that's left up to the user. Optional. Defaults to undefined.

service

Name of the xvfb service. This class will create an init script with this name and manage a service by this name. Defaults to xvfb

Class: display::x11vnc

display

X display to use. Default is 0

runuser

User to run xvfb as. Default is 'root'

package

Package name for installing x11vnc. Defaults to x11vnc on RedHat and Debian systems.

service

Name of the x11vnc service. This class will create an init script with this name and manage a service with this name. Defaults to x11vnc

x11vnc_bin

Absolute path to the x11vnc executable. Defaults to /usr/bin/x11vnc on RedHat and Debian systems and /usr/local/bin/x11vnc on FreeBSD.
