1 1.1 mrg Cygwin/X Release Notes 2 1.1 mrg ====================== 3 1.1 mrg 4 1.1 mrg Release X11R6.7 5 1.1 mrg =============== 6 1.1 mrg 7 1.1 mrg Cygwin/X has continued its rapid pace of development that it has sustained 8 1.1 mrg since Spring 2001 and this release shows it, we now have: a stable and fast 9 1.1 mrg multi-window mode, seamless clipboard integration, a configurable tray menu 10 1.1 mrg icon, popups on error messages pointing users to the log file and our mailing 11 1.1 mrg list, the beginnings of indirect 3D acceleration for OpenGL applications, 12 1.1 mrg improved non-US keyboard and clipboard support, and only a handful of bugs 13 1.1 mrg that continue to be reported. 14 1.1 mrg 15 1.1 mrg Between the XFree86 4.3.0 release and the X.Org X11R6.7 release the Cyg- 16 1.1 mrg win/XFree86 project broke away from The XFree86 Project, Inc. due to a lack 17 1.1 mrg of support from the XFree86 project. As such, the Cygwin/XFree86 project was 18 1.1 mrg renamed to the Cygwin/X project and the upstream source code tree that Cyg- 19 1.1 mrg win/X pulls from and pushes to is now the tree managed by the X.Org Founda- 20 1.1 mrg tion. The Cygwin/X project has seen a rush of development and interest in 21 1.1 mrg the project since the split; one metric showing this is that the number of 22 1.1 mrg CVS committers we have has gone from zero to six. 23 1.1 mrg 24 1.1 mrg The most outstanding features of this release are 25 1.1 mrg 26 1.1 mrg o Major multi-window mode improvements. (Takuma Murakami, Earle F. 27 1.1 mrg Philhower III) 28 1.1 mrg 29 1.1 mrg o Initial work of accelerated OpenGL using the windows OpenGL drivers. 30 1.1 mrg (Alexander Gottwald) 31 1.1 mrg 32 1.1 mrg o Massive rework of clipboard integration with windows. (Harold L Hunt II, 33 1.1 mrg Kensuke Matsuzaki) 34 1.1 mrg 35 1.1 mrg o Improved Japanese clipboard and keyboard support. (Kensuke Matsuzaki, 36 1.1 mrg Takuma Murakami, Alexander Gottwald) 37 1.1 mrg 38 1.1 mrg o Customizable tray menu icon allowing shortcuts to start programs, 39 1.1 mrg etc.(Earle F. Philhower III) 40 1.1 mrg 41 1.1 mrg o New icons. (Jehan Bing, Michael Bax, Benjamin Rienfenstahl) 42 1.1 mrg 43 1.1 mrg o Fix some multi-monitor problems.(Takuma Murakami) 44 1.1 mrg 45 1.1 mrg o Fix repeated key strokes. (Ivan Pascal) 46 1.1 mrg 47 1.1 mrg o Automatic keyboard layouts for the most frequently used keyboard lay- 48 1.1 mrg outs. (Alexander Gottwald) 49 1.1 mrg 50 1.1 mrg o Built in SHM support with detection of the SHM engine (cygserver). 51 1.1 mrg (Ralf Habacker, Harold L Hunt II) 52 1.1 mrg 53 1.1 mrg o Merged in work on the NativeGDI engine. (Alan Hourihane) 54 1.1 mrg 55 1.1 mrg OpenGL with Cygwin/X 56 1.1 mrg ==================== 57 1.1 mrg 58 1.1 mrg Cygwin/X has supported GLX only with software rendering provided by the Mesa 59 1.1 mrg library. Starting with X11R6.7 we add support for hardware accelerated OpenGL. 60 1.1 mrg 61 1.1 mrg This support is still under development and still has some bigger problems. 62 1.1 mrg To provide both versions (the stable software rendering and the new hardware 63 1.1 mrg accelerated) we ship to binaries. XWin.exe contains the software rendering 64 1.1 mrg and XWin_GL.exe uses the hardware acceleration provided by the windows drivers. 65 1.1 mrg 66 1.1 mrg The known problems with hardware accelerated OpenGL are: 67 1.1 mrg 68 1.1 mrg o Only multiwindow mode is useful. In the other modes the OpenGL output 69 1.1 mrg does not align with the X11 windows. 70 1.1 mrg 71 1.1 mrg o Using two programs which require different visuals will fail. For example 72 1.1 mrg glxgears and glxinfo will not work without restarting XWin_GL.exe. 73 1.1 mrg 74 1.1 mrg o OpenGL extensions and functions from OpenGL 1.2 and later should work 75 1.1 mrg but are not completely tested. 76 1.1 mrg 77 1.1 mrg o The standard Windows OpenGL driver will produce no output. Use the one 78 1.1 mrg from your video adapter vendor. 79 1.1 mrg 80 1.1 mrg If you notice problems with some programs please send a message with the 81 1.1 mrg logfile /tmp/XWin.log and a short error description to <cygwin-xfree (a] cygwin.com> 82 1.1 mrg 83 1.1 mrg The hardware accelerated OpenGL was tested using: 84 1.1 mrg 85 1.1 mrg o glxgears 86 1.1 mrg o glxinfo 87 1.1 mrg o blender 88 1.1 mrg o tuxkart 89 1.1 mrg o GLUT demos (some did fail) 90 1.1 mrg o tuxracer (currently not working) 91 1.1 mrg 92 1.1 mrg 93 1.1 mrg Release X11R6.8 94 1.1 mrg =============== 95 1.1 mrg 96 1.1 mrg Having reached a quite mature state in release X11R6.7 the development 97 1.1 mrg has slowed down a little bit. Some of the former active developers have 98 1.1 mrg retired or cut their work for the Cygwin/X project due to conflicts with 99 1.1 mrg job, study and family. 100 1.1 mrg 101 1.1 mrg The X11R6.8 release now includes major improvements from the xserver project. 102 1.1 mrg This includes the XFixes, Damage, Composite and XEVIE extension which is a 103 1.1 mrg major step towards allowing Cygwin/X to have real transparency. 104 1.1 mrg 105 1.1 mrg But at the current state Composite is not working with Cygwin/X. Not all code 106 1.1 mrg in the Cygwin/X Server has been updated to support the Composite feature and 107 1.1 mrg using it will even crash the xserver. But as a second problem nearly all 108 1.1 mrg functions required for compositing are lacking acceleration in Cygwin/X so 109 1.1 mrg the feature would not be very useful if it would work. So it is disabled by 110 1.1 mrg default. 111 1.1 mrg 112 1.1 mrg OpenGL with Cygwin/X 113 1.1 mrg ==================== 114 1.1 mrg 115 1.1 mrg The OpenGL support has lost some of it's limitations from the last release 116 1.1 mrg and should be much more stable. But due to missing wide spread testing in 117 1.1 mrg the community it is still available in a separate program. XWin still uses 118 1.1 mrg the old software OpenGL which is known to be stable. 119 1.1 mrg 120 1.1 mrg The known problems with hardware accelerated OpenGL are: 121 1.1 mrg 122 1.1 mrg o Only multiwindow mode is useful. In the other modes the OpenGL output 123 1.1 mrg does not align with the X11 windows. 124 1.1 mrg 125 1.1 mrg o OpenGL extensions and functions from OpenGL 1.2 and later should work 126 1.1 mrg but are not completely tested. 127 1.1 mrg 128 1.1 mrg o The standard Windows OpenGL driver will produce no output. Use the one 129 1.1 mrg from your video adapter vendor. 130 1.1 mrg 131 1.1 mrg If you notice problems with some programs please send a message with the 132 1.1 mrg logfile /tmp/XWin.log and a short error description to <cygwin-xfree (a] cygwin.com> 133 1.1 mrg 134 1.1 mrg The hardware accelerated OpenGL was tested using: 135 1.1 mrg 136 1.1 mrg o glxgears 137 1.1 mrg o glxinfo 138 1.1 mrg o blender 139 1.1 mrg o tuxkart 140 1.1 mrg o GLUT demos (some did fail) 141 1.1 mrg 142
