Configure the Window Environment
Once you have set the display mode, you can configure your system
to run either the OpenWindow or the CDE window environment.
NOTE: Board instances are assigned by the system.
Running OpenWindow from the console
For a one-headed system, type:
openwin -dev /dev/dx2pci0.0
For a two-headed system, type:
openwin -dev /dev/dx2pci0.0 -dev /dev/dx2pci0.1
Each device file has a name of this form:
/dev/dx2pciy.z
where y = board instance
z = head number (0 for first head, 1 for second head)
For more information on openwin, refer to your Sun OpenWindow
documentation.
Configuring the Common Desktop Environment
If you boot up to the X Window System, use the instructions below to
configure it for your DX2 board.
CDE defaults to using a single framebuffer associated with /dev/fb,
the boot console. To change the startup configuration, copy the
/usr/dt/config/Xservers file to /etc/dt/config/Xservers, and edit it
there.
This file contains mostly comments, but the last line is the
command line used to start the X server and bring up CDE.
This is the default line:
:0 Local local_uid@console root /usr/openwin/bin/Xsun \
:0 -nobanner
