X Server configuration

Chapter 2 11


Configuration of the X Server is supported through SAM via an icon titled X

Server Configuration. This icon resides either at SAMs top level or under the

top-level Display icon. This location is determined by the version of the HP-UX

operating system (later HP-UX releases will place X Server Configuration under

the Display folder).

There are several X*screens files used to configure the operation of the X Server.

The SAM graphical user interface for X Server configuration is provided to simplify

complexity and facilitate ease of use. While it is still possible to modify these files

manually (see below), using the SAM interface greatly simplifies the process for

creating Multi-Display and Single Logical Screen configurations.

Our SAM component has the following actions:

Configure Print Server Modify Multi-Screen Layout

Modify Server Options

Single Logical Screen (SLS)

--------------------------------

Describe Screen

Identify Screen

Modify Default Visual

Modify Screen Options Add Screen to Configuration

Remove Screen from Configuration

The first group of actions can be thought of as global actions. They will typically

be active regardless of what has been selected. If any of these menu items is not

visible, it is because it is not supported under the current configuration. For

example, on systems containing only one graphics screen, the last three menu items

will not be visible.The second group of actions can be thought of as screen actions. They will be

activated depending on which screens have been chosen. It is also possible that the

X*screens file

files.

description of the X*screens configuration file

This file belongs in /etc/X11/X*screens, where * is the display number of

the server. For example, the X0screens file is used when the $DISPLAYenvironment variable is set to hostname:0.screen and the server is invokedusing the :0 option.

The X*screens file is used to specify:

Device-independent server options, and

For each screen:

what device file to use (required), the default visual,

monitor size, and

device-dependent screen options.

Note that all of the items above, except for device-independent server options, are

specified on a per-screen basis.

The X Server supports up to four screens at a time. Specifying more than four

screens will cause a server error message.

Blank lines and comments (text following #) are ignored.

Chapter 214

The X Server delays loading of some X extensions until the first protocol request to

the given extension is received. Specifying this server option forces all extensions tobe loaded at X Server startup. The 11.00 X Server patches shipped after July, 1997

perform delayed loading of X extensions.

screen entries

The minimum screen entry is a line with the keyword Screen followed by a screen

device file.

Optional specifications for default visual, monitor size, and device-dependent

screen options may follow this minimal screen description line.

DefaultVisual

This optional part of the format specifies the default visual that the screen uses.

Valid keywords following the DefaultVisual keyword are Class, Depth,

Layer, and Transparent.

If no default visual is specified, then the standard default visual class, depth, layer,and transparency for the graphics device is used.

Not all default visual specifications will work on all devices.

If there is an error in a specification, look in an information file for more details (for

example, /usr/lib/X11/Xserver/info/screens/hp), in case it is newerthan the document youre now reading.

Transparent

Specify that a visual with an application-accessible transparent entry in the default

colormap be used.

MonitorSize Inches | MM

Specify the diagonal size of the monitor. After the MonitorSize keyword, you

must specify the diagonal length of the monitor and then the units. Use this entryonly if you are using a non-standard monitor.

MinimumMonitorPowerSaveLevel

Specify the minimum power save level to be used by the monitor during screen

blanking. You must specify a level of 0 -3 If the option is not used, the default is

ScreenOptions

Screen options are device-dependent options that are documented in a file in the X

Configura tion of th e X Server is support ed th rough SAM via an icon

tit led X Server Configura tion. This icon resides eith er at SAMs

top-level or under the top-level Display icon.

The SAM gra phical user int erface for X Server configura tion is provided

to simplify complexity a nd facilitat e ease of use in m odifying or creat ing

th e X Server configura tion file, XF86Config. The Xf86 server uses th eXF86Config file for its configur at ions. While it is st ill possible to modify

th is file man ua lly (see below), usin g the SAM inter face can grea tly

simplify the process.

The SAM component ha s th e following actions:
