6.2.2 Do Not Modify the keymaps.dir File
The final revision of the X Keyboard Extension, XKB Version 1.0, will be
different from XKB Version 0.65, shipping with this release. The format of
/usr/lib/X11/xkb/keymaps.dir will change. Do not modify this
file as it will not be preserved with future updates of the operating system.
To force the server to use a specific XKB keymap, add the -xkbmap option
to the server options line in /usr/lib/X11/Xserver.conf. Refer to
the Xdec(1X) reference page on for more information.
6.3 X Clients
The following notes apply to X clients.
6.3.1 X Window Colormap Resources
Color rich applications, such as Netscape, exhaust a large number of
colormap resources. This results in problems with other graphical
applications. For example, you may notice that icons normally displayed by
the CDE Application Manager are not displayed when a color rich
application is currently running on the system. Graphics applications and
online help volumes may also be affected. The icon editor, dticon, may
not be able to open a pixmap that contains a large number of colors.
In most cases this is a visual problem, and it may not be necessary to take
any corrective actions. You can use the CDE icon labels in the same way as
the icon for user actions such as drag-and-drop, and single and double click.
The simplest solution is to exit the color rich application. There are several
alternate actions:
• Use the CDE Style Manager’s Color application to select the number of
colors used by the desktop or an application. Alternatively, if supported:
– Set an application resource to limit color usage.
– Start the application with a flag that controls color map installation.
(Refer to the application documentation for further details.)
• In the case of Netscape, two workarounds are available; the first is
preferred:
– Use Netscape’s maxImageColors resource to limit the number of
colors that Netscape uses. A suggested limit is 96. You can do this
