Cygwin/X Release Notes
|
|
======================
|
|
|
|
Release X11R6.7
|
|
===============
|
|
|
|
Cygwin/X has continued its rapid pace of development that it has sustained
|
|
since Spring 2001 and this release shows it, we now have: a stable and fast
|
|
multi-window mode, seamless clipboard integration, a configurable tray menu
|
|
icon, popups on error messages pointing users to the log file and our mailing
|
|
list, the beginnings of indirect 3D acceleration for OpenGL applications,
|
|
improved non-US keyboard and clipboard support, and only a handful of bugs
|
|
that continue to be reported.
|
|
|
|
Between the XFree86 4.3.0 release and the X.Org X11R6.7 release the Cyg-
|
|
win/XFree86 project broke away from The XFree86 Project, Inc. due to a lack
|
|
of support from the XFree86 project. As such, the Cygwin/XFree86 project was
|
|
renamed to the Cygwin/X project and the upstream source code tree that Cyg-
|
|
win/X pulls from and pushes to is now the tree managed by the X.Org Founda-
|
|
tion. The Cygwin/X project has seen a rush of development and interest in
|
|
the project since the split; one metric showing this is that the number of
|
|
CVS committers we have has gone from zero to six.
|
|
|
|
The most outstanding features of this release are
|
|
|
|
o Major multi-window mode improvements. (Takuma Murakami, Earle F.
|
|
Philhower III)
|
|
|
|
o Initial work of accelerated OpenGL using the windows OpenGL drivers.
|
|
(Alexander Gottwald)
|
|
|
|
o Massive rework of clipboard integration with windows. (Harold L Hunt II,
|
|
Kensuke Matsuzaki)
|
|
|
|
o Improved Japanese clipboard and keyboard support. (Kensuke Matsuzaki,
|
|
Takuma Murakami, Alexander Gottwald)
|
|
|
|
o Customizable tray menu icon allowing shortcuts to start programs,
|
|
etc.(Earle F. Philhower III)
|
|
|
|
o New icons. (Jehan Bing, Michael Bax, Benjamin Rienfenstahl)
|
|
|
|
o Fix some multi-monitor problems.(Takuma Murakami)
|
|
|
|
o Fix repeated key strokes. (Ivan Pascal)
|
|
|
|
o Automatic keyboard layouts for the most frequently used keyboard lay-
|
|
outs. (Alexander Gottwald)
|
|
|
|
o Built in SHM support with detection of the SHM engine (cygserver).
|
|
(Ralf Habacker, Harold L Hunt II)
|
|
|
|
o Merged in work on the NativeGDI engine. (Alan Hourihane)
|
|
|
|
OpenGL with Cygwin/X
|
|
====================
|
|
|
|
Cygwin/X has supported GLX only with software rendering provided by the Mesa
|
|
library. Starting with X11R6.7 we add support for hardware accelerated OpenGL.
|
|
|
|
This support is still under development and still has some bigger problems.
|
|
To provide both versions (the stable software rendering and the new hardware
|
|
accelerated) we ship to binaries. XWin.exe contains the software rendering
|
|
and XWin_GL.exe uses the hardware acceleration provided by the windows drivers.
|
|
|
|
The known problems with hardware accelerated OpenGL are:
|
|
|
|
o Only multiwindow mode is useful. In the other modes the OpenGL output
|
|
does not align with the X11 windows.
|
|
|
|
o Using two programs which require different visuals will fail. For example
|
|
glxgears and glxinfo will not work without restarting XWin_GL.exe.
|
|
|
|
o OpenGL extensions and functions from OpenGL 1.2 and later should work
|
|
but are not completely tested.
|
|
|
|
o The standard Windows OpenGL driver will produce no output. Use the one
|
|
from your video adapter vendor.
|
|
|
|
If you notice problems with some programs please send a message with the
|
|
logfile /tmp/XWin.log and a short error description to <cygwin-xfree@cygwin.com>
|
|
|
|
The hardware accelerated OpenGL was tested using:
|
|
|
|
o glxgears
|
|
o glxinfo
|
|
o blender
|
|
o tuxkart
|
|
o GLUT demos (some did fail)
|
|
o tuxracer (currently not working)
|

|
Release X11R6.8
|
|
===============
|
|
|
|
Having reached a quite mature state in release X11R6.7 the development
|
|
has slowed down a little bit. Some of the former active developers have
|
|
retired or cut their work for the Cygwin/X project due to conflicts with
|
|
job, study and family.
|
|
|
|
The X11R6.8 release now includes major improvements from the xserver project.
|
|
This includes the XFixes, Damage, Composite and XEVIE extension which is a
|
|
major step towards allowing Cygwin/X to have real transparency.
|
|
|
|
But at the current state Composite is not working with Cygwin/X. Not all code
|
|
in the Cygwin/X Server has been updated to support the Composite feature and
|
|
using it will even crash the xserver. But as a second problem nearly all
|
|
functions required for compositing are lacking acceleration in Cygwin/X so
|
|
the feature would not be very useful if it would work. So it is disabled by
|
|
default.
|
|
|
|
OpenGL with Cygwin/X
|
|
====================
|
|
|
|
The OpenGL support has lost some of it's limitations from the last release
|
|
and should be much more stable. But due to missing wide spread testing in
|
|
the community it is still available in a separate program. XWin still uses
|
|
the old software OpenGL which is known to be stable.
|
|
|
|
The known problems with hardware accelerated OpenGL are:
|
|
|
|
o Only multiwindow mode is useful. In the other modes the OpenGL output
|
|
does not align with the X11 windows.
|
|
|
|
o OpenGL extensions and functions from OpenGL 1.2 and later should work
|
|
but are not completely tested.
|
|
|
|
o The standard Windows OpenGL driver will produce no output. Use the one
|
|
from your video adapter vendor.

|

|
