Xserver for NetBSD/dreamcast

[English] [Japanese]

NOTICE

The X server for NetBSD/dreamcast has already included NetBSD/dramcast after 3.0. Please use official source or binary.

What is this?

This is the X server and X clients for NetBSD/dreamcast, it supports only 640x480/16bpp screen , and does not use any acceleration of PowerVR2 (only use frame-buffer). It is ported from Xhpc for NetBSD/hpc based on X11R6.3/XFree86 3.3.6.

This works only after NetBSD 1.6U (will not work on NetBSD 1.6.1).

Files

• kernel-20030813.diff.gz - kernel patch for mms(4) and pvr(4)
• xsrc-dreamcast-20030813.diff.gz - diff of xsrc includes Xdreamcast sources

Kernel patch

Before you run an Xserver, you have to run the patch to kernel as follows:

  # cd /usr/src
  # zcat /where/path-to-patch/kernel-20030813.diff.gz | patch -p0

Then, rebuild your kernel of NetBSD/dreamcast.

This patch will change the vertical-direction(Delta-Y) of mms(4) and add Video ON/OFF ioctl(WSDISPLAYIO_SVIDEO) to pvr(4) for screen saver.

How to make

1. Checkout xsrc from NetBSD CVS repository.
2. Patch sources to xsrc as follows:

     # cd /your/xsrc
     # zcat /where/path-to-patch/xsrc-dreamcast-20030813.diff.gz | patch -p0
   

3. Make and make install in xsrc on NetBSD/dreamcast (it means 'self build').

     # cd /your/xsrc
     # make 
     # make install
   

   If success, /usr/X11R6 will be created.

   Make error will occur in xsrc/local/programs/x11-ssh-askpass as follows:

     make: don't know how to make -lXt. Stop
   

   I think it is a bug of x11-ssh-askpass/Imakefile or xsrc/xc/config/cf/X11.tmpl. It will success to remove the following line of xsrc/local/programs/x11-ssh-askpass/Makefile, but it is not so good.

             DEPLIBS = $(LOCAL_LIBRARIES)  
   

Before run Xserver

1. Edit /etc/ttys as follows:

   console "/usr/libexec/getty std.115200" vt100  off secure
   ttyE0   "/usr/libexec/getty std.115200" vt100  on  secure
   

   It is not necessarily required, but it is easy to run Xserver.

2. Connect dreamcast keyboard and dreamcast mouse.
3. Reboot your NetBSD/dreamcast.

How to run

1. login as your account to NetBSD/dreamcast from Console (Not from network).
2. Add /usr/X11R6/bin to your PATH.
3. Run xinit or startx from console.
4. Welcome to X Window System on NetBSD/dreamcast!

xdm(1) will work, too.

Notice

• This Xserver is very experimentally, so it may have some bugs.
• The keyboard layout is US ascii. If you want to use another keymap, use xmodmap(1).
• If you don't patch your kernel, the vertical direction of mouse will invert.
• This makes only static binary. I don't have an environment to make dynamic library for NetBSD/dreamcast. If you have, please change xc/config/cf/NetBSD .cf to make dynamic library and test it.

More X clients. Mosaic, xengine, w3m-img, and etc. Heavy load...
