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. + +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) + |
