The newer <tt>kbd</tt> +driver replaces the older built-in driver. It is suggested that, if the +X server says that it cannot load the keyboard driver, then the +<tt>xorg.conf</tt> file should be updated to use the new <tt>kbd</tt> +driver, which can be done by changing the <tt>Driver</tt> line in the +<tt>InputDevice</tt> section. For example, + +<verb> +Section "InputDevice" + Identifier "Keyboard0" + Driver "kbd" +EndSection +</verb> +Note that the driver name is case-sensitive. + +<sect1>Socket directory ownership and permissions +<p> +The socket directories created in <tt>/tmp</tt> are now required to be +owned by root and have their sticky-bit set. If the premissions are not +set correctly, the component using this directory will print an error +message and fail to start. Common socket directories that are known to +be affected include: +<verb> +/tmp/.font-unix +/tmp/.ICE-unix +/tmp/.X11-unix +</verb> +These directories are used by the font server, <tt>xfs</tt>, +applications using the Inter-Client Exchange protocol (ICE) and the X +server, respectively. +<p> +There are several solutions to the problem of when to create these +directories. They could be created at install time by the system's +installer if the <tt>/tmp</tt> dir is persistent. They could be created +at boot time by the system's boot scripts (e.g., the <tt>init.d</tt> +scripts). Or, they could be created by PAM modules at service startup +or user login time. +<p> +The solution chosen is platform dependent, and the system administrator +should be able to handle creating those directories on any systems that +do not have the correct ownership or permissions. + +<sect1>Composite exposes extra visuals +<p> +When the Composite extension is enabled via <tt>xorg.conf</tt> or the +command line, a new visual is created. This visual is different from +the other visuals used by X applications in that it includes an alpha +component. It is used by the compositing manager and other Composite +aware applications. +<p> +Most X applications ignore this visual since it is not useful to them; +however some applications mistakenly try to use it, which will cause +them to fail. An environment variable, <tt>XLIB_SKIP_ARGB_VISUALS</tt>, +was added to the X11 library to hide this visual from applications that +mistakenly try to use it. If an application fails only when the +Composite is enabled, try setting this environment variable before +starting the application. +<p> +Since Composite is not enabled by default, it is not expected that this +issue will be visible to most users. <sect>Attributions/Acknowledgements/Credits |
