The net result is much faster drawing and support for all the Amiga's -custom display depths but, as usual, the fewer planes used, the faster the -drawing operations of the X server. Even so, on my A1200 with a 33Mhz 68030, -I'm getting reasonable performance when using 8 bit planes in Dbl NTSC mode. - -Installation ------------- - -You will need to have first obtained and installed the X11R6 binary -distribution available from ftp.uni-regensburg.de in -/pub/NetBSD-Amiga/contrib/X11 or one of its mirrors.

To workaround this problem, log on as superuser and then -either make Xdaniver setuid root: - - chown root Xdaniver - chmod 4755 Xdaniver - -or give everyone access the devices: - - chmod 666 /dev/kbd /dev/mouse /dev/view?? - -the latter option is a possible cause of a security hole if your machine is -ever used multi-user. - -General Information -------------------- - -The default resolution of the server is 700x430 and the default depth 4. AGA -users might what to increase the display depth by editing the startx script -and providing a -depth <depth> argument to Xdaniver on the xinit line of the -script. As always, the lower the depth, the faster the drawing and window -manipulation of the server. - -The resolution can be altered similarly by suppling -width <width> and --height <height> arguments to the server. - -The NetBSD kernel selects actual screen modes by picking a mode who's -natural, non-overscanned size best-fits the requested resolution. -Unfortunately, for AGA users, the 1.0 kernel only has support for the -Dbl-NTSC AGA display mode and only this mode has support for depths greater -than 4. The NetBSD-current (work-in-progress) kernel also has support for -Dbl-PAL but still no support for the Super72 or other super-hires modes -(perhaps some kind, kernel-hacker could add support for them ?). - -If you have a 2 button mouse (like me) you might want to try and use the 3 -button mouse emulation. On other systems, it is usual for the left and right -buttons to be provided and emulate the middle button by pressing both -buttons together, however, the middle button is tends to be used more than -the right button so I have provided two options: - --emulateright (or -3), the two physical mouse buttons act as left and middle -and pressing them both together emulates the right button. - --emulatemiddle (or -2), the two physical mouse buttons act as left and right -and pressing them both together emulated the middle button. - -When using screen depths of less than 6 (4 is the maximum for ECS machines) -the lack of possible colours on screen at once causes problems for many X -applications. Specifying -cc 2 as a command line argument to Xdaniver -causes the server to switch the default visual type from PsuedoColor to -StaticColor; to put it simply, the server prefills the colormap with a -selection of 16 colours (depth 4) and when an application asks for a -particular colour, its gets allocated one that is closest to one from the -selection of 16. This removes the 'WARNING: Cannot allocate colormap entry -for "XXX"' errors but at the expense of applications not being able to get -the precise colour they wanted. Also, some badly written X applications fail -altogether when presented with a StaticColor visual. - -Bugs/Limitations ----------------- - -The limited choice of display resolutions for AGA/ECS machines is a real -pain - requires a kernel change to fix. Worse still, the kernel specifies -the maximum overscan resolution on the Dbl-NTSC to be 724x482 but selecting -anything more than 702x430 on my machine causes the screen either sheer -diagonally (as if the bytes per row calculation in Xdaniver or the kernel is -wrong) or completely loose sync (suggesting a custom chip register sync -calculation bug). As other, non-aga modes aren't affected when selection -overscan both problems seem to point to a kernel driver bug. Also, depths -greater than 4 for AGA users are only supported by the kernel in the Dbl-NTSC -mode (and Dbl-PAL with the current-NetBSD kernel). - -I know of one bug so-far (there will be more), The PutImage request of an XY -format image expects the bitplane order to be the reverse of that specified -in the X protocol but since virtually all applications use the Z (chunky) -format, you are unlikely to come across this problem. - -The PutImage request of Z format images is a little slow - when I have time -I'll try and add one of the fast assembly chunky-to-planar routines developed -for doom style games/demos. Unfortunately, the current crop all require a -picture size that is a multiple of 32 pixels and so cannot be used out-of-the- -box. - -Some extra performance could easily be squeezed out of the terminal font -drawing code (used by xterm) - when I have time I'll add the code. - -The Amiga's blitter and sprites are totally unused and will remain so -until/if someone else adds support to the kernel. The blitter would help -speed up screen scrolling and window manipulation and sprite support could -be used for the X pointer shape (if small enough) which would speed up all -drawing operations (no need to remove the software based pointer shape -first, draw, then replace the pointer shape). - -I removed the X image extension (XIE) from the X server as it increased the -size of the binary by some 400k. I haven't come across any applications that -need it yet (I haven't been looking!) so if you need the extension for some -reason send me e-mail and I'll build a server with the extension included. - -The 3 button mouse emulation is very simple - to emulate the 3rd button you -have to press both button precisely at the same moment - I've got quite good -at it now. When I have some spare time I'll add a timer so you will have a -few milli-seconds between one button being pressed and the next and it still -being registered as the emulated button. - -AGA users don't forget to provide the -A flag to loadbsd to enable the one -AGA mode in the 1.0 kernel but only if you have a VGA, multisync or dual-scan -monitor, of course ! - -Xdaniver has been tested on: - -A1200, 33Mhz 68030, 8Mb RAM and NetBSD 1.0 by myself. -A4000/40, 12Mb RAM and NetBSD 1.0 by Andreas Holzhammer. -A3000, 12Mb RAM and NetBSD 1.0 by Charlie Root, Stuart Park and others. -A3000, 25Mhz 68040, 18Mb RAM and NetBSD-current by Michael K. Sanders. -A2000, 8Mb RAM and NetBSD (version unknown) by Hubert Feyrer. - -Release and Bug Fix History ---------------------------- - -1.0 - First release - -1.01 Bugs fixed: - - Narrow (<32 pixels) Z format GetImage requests corrupted the stack - and could cause the server to core dump. (Xpaint caused this problem) - - Drawing dots (PolyPoint request) into a clipped window caused a - c pointer to go out of range, causing a core dump (xv showed this - problem). - - New features: - - Simple 3 button mouse emulation using a 2 button mouse; specify - -emulate_middle (or -2) or -emulate_right (or -3) on the server's - command line and press both mouse buttons together emulate the 'missing' - button. - - Basic beep sound support added by sending bell characters to the - console. - - Source code released. - -Disclaimer and Copyright Notices --------------------------------- - -Multi-depth planar frame buffer code: -Copyright (c) 1995 by Daniver Limited. - -Large portions: -Copyright (c) 1994 by Eduardo Horvath. -Copyright (c) 1987-1995 by the Regents of the University of California. -Copyright (c) 1987 by Sun Microsystems, Inc.
