How can I configure a second monitor or change X server options?



First, you simply plug in the second framebuffer; plug in the monitor,
make sure you have the correct device drivers installed and
do a reconfiguration boot.


The X server is started through the dt/config Xservers file; you'll
need to modify it when you change your X server configuration:



# Never edit the /usr/dt/config files in place
mkdir -m 755 -p /etc/dt/config
cp /usr/dt/config/Xservers /etc/dt/config


Edit the Xservers file and change the line with "local_uid@console"
to suit your needs; the Xsun(1) describes what arguments to pass.


Here are some examples (lines split for clarity):



# FFB as left monitor, PGX (m64) to the right (two ways)
:0 Local local_uid@console root /usr/openwin/bin/Xsun :0 -nobanner \
-dev /dev/fbs/ffb0 -dev /dev/fbs/m640
:0 Local local_uid@console root /usr/openwin/bin/Xsun :0 -nobanner \
-dev /dev/fbs/m640 -dev /dev/fbs/ffb0 left

# FFB, PGX (m64) underneath
:0 Local local_uid@console root /usr/openwin/bin/Xsun :0 -nobanner \
-dev /dev/fbs/m640 -dev /dev/fbs/ffb0 top

# 2x FFB, using a default 24 bit visual instead of the standard 8
:0 Local local_uid@console root /usr/openwin/bin/Xsun :0 -nobanner \
-dev /dev/fbs/ffb0 defdepth 24 -dev /dev/fbs/ffb1 defdepth 24
