This is another public release of my attempt to build an X11 server for Amiga. It is supposed to fix all known bugs from the previous release and may even have some new features. For details, see changes below. Contact: -------- email: dspach@free.fr web: http://dspach.free.fr Changes: -------- * main changes in v040 hopefully, Cybergraphics and/or Mediator users should be able now to use the server with almost all features: - PiP on Cybergraphics is supported without hardware acceleration but only for rgb16pc pixel formats - Window mode on Cybergraphics is supported without hardware acceleration (as on P96) - rgb16pc as all other XXXXpc pixel formats are supported also without hardware acceleration, however, some rare complex graphic ops will not be shown correctly (i.e. will display wrong colors). this has been tested on a WB3.0 machine with P96 V2 and CGX V42 with the latest updates available, graphic card being a PicassoIV. * main changes in v030 this release is now fully based on Xfree402 source code IMPORTANT: amiga specific options syntax has changed to avoid options name clashes with Xfree one's, this is now Xami402 [regularXoptions] -amiga:option1,option2,option3 ... features - only one version for RTG and OCS/ECS/AGA - built-ins fixed fonts and cursors - depth support 4/8/15/16/24/32 bits per pixel - always use a colormap for depth <= 8 - hardware cursor is enabled by default - work-around for clients using little endian pixmaps - may display in a window - may display in a PiP window - Workbench tooltypes handling has changed, see below Requirements: ------------- - WB 3.0 or up - 020, 030, 040 or 060 CPU with FPU - network subsystem such as AmiTCP, Genesis or Miami Supported depth, pixel formats and additionnal requirements: * Xami402 - depth 4 bits for OCS/ECS chipsets - depth 4 or 8 bits for AGA chipsets when using a graphic card: - requires RTG system such as Cybergraphics (V41) or Picasso96 (V2) - depth 8, 15, 16, 24, 32 bits - window mode requires Picasso96 V2 or CGFX V42 - PiP window mode requires Picasso96 V2 or CGFX V42r7 NOTE1: some knowledge about X11 is required, since I'm not going to supply it ! NOTE2: no more fonts are provided in this distribution since this release has some built-ins fonts and cursors. But most clients will require more fonts, so you may get them from my site, from the Geek Gadgets distribution at http://www.ninemoons.com or from any BSD/Linux distribution. Fonts must be dropped in X11ami:lib/X11/fonts/font-type-dir, just make sure that fonts.dir and fonts.alias files have the correct content (see an X font manual for description). Useful links: ------------- X is a big subject on his own, so you may find some related infos at http://www.xfree86.org http://www.rahul.net/kenton Usage: ------ Before starting the server, make sure to launch the MakeAssign icon, since an assign is required for the server to find fonts and bitmaps at the right place. To learn the Workbench ToolTypes and/or CLI options, use a CLI and type: X11ami:Xami402 zzz Almost all the CLI options are the same as the standart X11 servers found in the Un*x world. Amiga specific options are: noaccel turn off graphic acceleration. This will considerably slowdown graphics operations such as on screen rectangle fills or blittings. However this may in some cases be safer. nohwcursor disable hardware cursor emulation nolock This is a dangerous option that may crash your machine, you have been warned. This will remove the locking/unlocking mechanism of the screen or PIP bitmap. nocbpixe turn off pixmap endianness work-around planar use native Amiga chipset instead of RTG card pip show X display in a PiP window, you need a graphic card that has Picture in Picture capability. Some more restrictions may apply for your card, e.g. 8 bits PiP on a 16 bits screen, etc .... Consult your P96 or CGFX documentation. window show X display in a window of the default public screen. The depth and the pixel format of the X display will be the same as the public screen one's. The public screen depth must be more than 8 bits, that is an RTG card is required. screen=mode use that 'mode' screen, the value may be specified in Hex or decimal. For a PAL Hires Screen Mode this value is 0x29000. priority=N set the foreground process priority when the server is running (process will go down to priority -1 when iconified) dpi=XxY set display resolution to X and Y dpi instead of defaults 75 pixel=format set pixel format such as rgb15, bgr24, argb32 ... WIDTHxHEIGHTxDEPTH use a display size of WIDTH and HEIGHT with a pixel that DEPTH Workbench usage: ---------------- If you want to start the server from Workbench you will have to setup the icon as a project whose tool is X11ami:Xami402 and provide tooltypes almost the same way as the CLI options. if you use from CLI Xami402 -amiga:800x600x16 -query pc -fp built-ins,tcp/pc:7100 then do on the icon - tool X11ami:Xami402 - 1st tooltype -amiga:800x600x16 - 2nd tooltype -query pc - 3rd tooltype -fp built-ins,tcp/pc:7100 NOTE4: in the above example, we use a host named pc (probably a Linux box) with a display manager (-query pc) and a font server on TCP port 7100, but built-ins server fonts are first searched Make sure also to modify the etc/X0.hosts file in order to allow remote machines to display on your amiga machine. Here are the settings I use to connect to my pc Linux box from my A4000 with AriadNE2 and PicassoIV cards: Xami402 -amiga:nolock,pip,960x720,pixel=rgb16,priority=1 :0 -query pc -fp built-ins,tcp/pc:7100 -once Shortkeys: ---------- - RAmiga-Q quit the server - RAmiga-R reset the server - RAmiga-M send screen or window to back - RAmiga-H iconify the server Known issues: ------------- - only TCP/IP transport is used even with local clients - does not check if PIP window is greater than screen - memory fragmentation (huge usage of alloc/free) - pixel=bgr24 shows wrong colors, as probably some other formats Please note also: ----------------- The following may apply if the nocbpixe option is used. Some applications running on Little Endian machines (PC's) display wrong colors on the Amiga server which is a Big Endian machine. For instance, StarOffice is known for that problem, as are some Window Managers. THIS IS NOT a bug of Xami !
