1. Introduction to the 4.x Release Series

XFree86 4.0 was the first official release of the new XFree86 4 series. The

current release (4.1.0) is the latest in that series. XFree86 4 represents a

current release (4.2.0) is the latest in that series. XFree86 4 represents a

significant redesign of the XFree86 X server. Not all of the hardware

drivers from 3.3.x have been ported to 4.x yet, but conversely, 4.x has some

hardware support not present in 3.3.x. Our Driver Status document summarizes

how the hardware driver support compares between 3.3.6 and 4.1.0. Please

Server implementation:

3. Drivers

o Implemented remaining code for client clip lists.

3.1 Video Drivers

XFree86 4.2.0 includes the following video drivers:

o Complete compositing code, except for separate alpha.

Todo:

o Polygons

o Image scaling

o Separate alpha channels

o Support for visuals other than TrueColor.

Drivers with render extension support include: i128, glint, ati (r128

and radeon), chips, cirrus, mga, neomagic, nv, tdfx, trident, tseng,

vesa, s3virge.

Acceleration for the render extension:

o XAA infrastructure for acceleration.

o Experimental MGA acceleration using XAA

o kdrive (TinyX) infrastructure

o Experimental TinyX Trident 9525DVD acceleration

Xft library:

o New font naming/access library.

o Abstraction for core/Render text.

o Uses FreeType2 rasterizer.

o Allows anti-aliased/subpixel sampled text.

o Gracefully falls back to core rendering.

o Complicated font matching mechanism.

o Uses server DPI to convert point sizes to pixel sizes, even for

core fonts.

xterm:

o Can use Xft, by default uses core fonts.

o Uses new options '-fa' for family name and '-fs' for font size (in

points).

x11perf:

o Add tests for anti-aliased, subpixel sampled and aliased fonts

using the Xft library.

xditview:

o When the Xft library is build, uses Xft for all font access.

Qt, Gtk, twm:

o Qt changes available here <URL:http://XFree86.org/~keithp/down-

load/qtkernel.tar.bz2>.

o Gtk changes in process.

o twm hacks should never see the light of day.

o xf86cfg, a new graphical configuration tool for XFree86 4.x, and can be

used to either write the initial configuration or make customisations to

the current configuration. xf86cfg is a work in progress, and allows

configuration of:

o Specific setup of monitors, cards, keyboards and mice, as well as

adding or removing them.

o Server layout setup, allowing complex configuration of physical

monitor positions, default color depth and/or rotated monitors.

o Mode line editor that can be used to configure multiple monitors,

and allows adding a modeline specific to a monitor directly to the

configuration file.

o AccessX configuration interface, that provides an interface to easy

setup of most AccessX options, including:

o Timeout to reset controls.

o StickyKeys, for people with disabilities that cannot press two

keys at the same time.

o MouseKeys, mouse control only with the keyboard.

o RepeatKeys, repeat rate and repeat delay.

o SlowKeys, to avoid pressing keys accidentally, they're only

accepted if pressed for some specific amount of time.

o BounceKeys, helps avoiding multiple key presses by only

accepting a key if it is pressed only once and not pressed

again in a specific amount of time.

New configuration options are being worked on, as well as correcting

some of the bugs in the current options. A protocol for plugging in

external modules is also planned.

3.2 X libraries and clients.

o Significant updates to the internationalisation support in Xlib (see

below (section 3.3, page 1)).

o Some xfs updates, including font path verification, and new options.

o XTerm updates.

o New "xvinfo" client for querying the XVideo extension.

3.3 Fonts and Internationalisation

o Many of the "misc" bdf fonts have been updated and extended, and a wider

range of ISO-8859 subsets have been added. These are now auto-generated

from ISO-10646 encoded master fonts.

o The ClearlyU ISO-10646 encoded fonts have been updated.

o Functions to read keyboard input in locale independent UTF-8 encoding

have been added to libX11: Xutf8LookupString, Xutf8ResetIC.

o Functions to output strings in locale independent UTF-8 encoding have

been added to libX11: Xutf8DrawString, Xutf8DrawImageString, Xutf8Tex-

tEscapement, Xutf8TextExtents, Xutf8TextPerCharExtents, Xutf8DrawText.

o Functions to convert between Compound Text or locale dependent encoding

and UTF-8 have been added to libX11: Xutf8TextListToTextProperty,

Xutf8TextPropertyToTextList. The converter between Compound Text and

UTF-8 in Xlib has been improved; a round-trip conversion now correctly

converts all graphic Unicode characters back and forth.

o libXaw now offers selected text using both selection targets,

UTF8_STRING and COMPOUND_TEXT.

o Locales with UTF-8 encodings are now supported; but the UTF-8 displaying

facilities are not adequate yet.

o XKB keyboard definitions have been added and updated for some countries.

3.4 Platforms

o Darwin/Mac OS X.

o Greatly improved IA-64 support.

o Improved Linux/mips support.

o Support has been added for more Alpha platforms under Linux. This now

includes all platforms that require sparse memory mapping.

5. Summary of XFree86 4.

4. Overview of XFree86 4.x.

Unlike XFree86 3.3.x where there are multiple X server binaries, each of

which drive different hardware, XFree86 4.1.0 has a single X server binary

which drive different hardware, XFree86 4.2.0 has a single X server binary

called XFree86. This binary can either have one or more video drivers linked

in statically, or, more usually, dynamically load the video drivers and other

modules that are needed.

XFree86 4.1.0 has X server support for most UNIX(R) and UNIX-like operating

XFree86 4.2.0 has X server support for most UNIX(R) and UNIX-like operating

systems on Intel/x86 platforms, plus support for Linux on Alpha, PowerPC,

IA-64, Sparc, and Mips platforms, and for Darwin on PowerPC. Work on support

for additional architectures and operating systems is in progress, and is

planned for future releases.

5.1 Loader and Modules

module updates in between major releases.

The loader in version 4.1.0 has support for Intel (x86), Alpha and PowerPC

The loader in version 4.2.0 has support for Intel (x86), Alpha and PowerPC

platforms. It also has preliminary support for Sparc platforms.

ends are based on the FreeType library.

characters. In particular, these fonts include all the glyphs needed for

Bigelow and Holmes Inc., and the hinting was donated by Berthold Horn and

The glyph coverage of the Type 1 versions is somewhat reduced, and only cov-

The Luxi fonts are original designs by Kris Holmes and Charles Bigelow from

Bigelow and Holmes Inc., who developed the Luxi typeface designs in Ikarus

mat fonts to TrueType and Type 1 font programs and implemented the grid-fit-
