- 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.

- Changes:
- --------
-
- * 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
- - PiP window mode requires Picasso96 V2
-
- 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

-
-
-
- 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 and you must use the Picasso96
- RTG system. Some more restrictions may apply for your card, e.g.
- 8 bits PiP on a 16 bits screen, etc .... Consult your P96 doc.
-
- window
-
- show X display in a window of the default public screen, here also
- Picasso96 RTG system is mandatory. The depth 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. (NOTE3)
-
- 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 ... (NOTE3)
-
- WIDTHxHEIGHTxDEPTH
-
- use a display size of WIDTH and HEIGHT with a pixel that DEPTH
-
-
-
- NOTE3:
- specifying a pixel format such as rgb15pc or rgb16pc without using the
- window mode will surely display color garbage. If your card only supports
- little endian 15/16 bits modes (rgb15pc or rgb16pc), do the following:
-
- - make the default public screen (Workbench probably) that format
- - use options: window,pixel=rgb15 or rgb16
-
- the window mode uses an off-screen frame buffer, and is able to do on
- the fly rgb15 to rgb15pc or rgb16 to rgb16pc conversions
-
-
-
- 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 !
