Hitchhiker's Guide to Openbsd

11.2.11 - mvme68k
No X servers, only X clients. 
11.2.12 - mvme88k
No X servers, only X clients. 
11.2.13 - sgi
X runs on the O2 system's frame buffer in unaccelerated mode. 
11.2.14 - sparc
/usr/X11R6/README
 for sparc. 
With a single supported framebuffer, there is no configuration needed. If you wish to use a multi-headed 
configuration, see the above README file for details. 
Resolution is controlled by the firmware before booting OpenBSD. 
11.2.15 - sparc64
/usr/X11R6/README
 for sparc64. 
Most simple configurations now "Just Work". If yours does not or you wish to get fancy, see the above 
README file. 
11.2.16 - vax

11 - The X Window System
/usr/X11R6/README
 for vax. 
The X server currently only works on VAXstation 4000 models with either a 
lcg(4)
 or 
lcspx(4)
framebuffer. 
11.2.17 - zaurus
/usr/X11R6/README
 for zaurus. 
No configuration needed, X "Just Works". 
11.3 - Configuring X on amd64 and i386
If you haven't tried 
just starting X
, stop! Don't make work for yourself if you you don't need to! Most 
i386 and amd64 users will find X Just Works without any manual configuration. 
11.3.1 - X.Org configuration
Sometimes, X does not "just work" as desired, and sometimes, you need to customize something that 
does work. 
If X does not work as desired with your system, you will need to create a configuration file. A good 
starting place (and sometimes, a good ending place!) is to run 
Xorg(1)
in the "X -configure" mode. This 
will load all available video driver modules, probes for other hardware, and based on what it finds, 
writes out a xorg.conf file that may or may not work. Even if it does not work, it will be a useful starting 
point for creating one that works as desired. 
Another time-honored way to configure X is to use your favorite search engine to hunt for someone else 
who already solved your problem. Note that 
xorg.conf
files for other Unix-like OSs will often 
provide very useful tips on what you need to get X running on your similar hardware. While that's not a 
bad way, that method won't be emphasized here.
