The default screen resolution varies on different solaris boxes -- it
depends on the monitor sense codes and frame buffer capabilities. In
most cases this will be the Sun 19/20" monitors with a resolution of
1280x1024. Default color depth is PseudoColor (8 bit) since some
applications do not handle TrueColor too gracefully.
An excellent reference page on more information was given as follows:
http://c3-a.snvl1.sfba.home.com/FrameBuffer.html
On this page, there is a downloadable ksh script (fbinfo) that detects
your framebuffer type and resolution. Here is my output:
$ fbinfo
cgsix@1 is GX 1152x900@66 Monitor type 0
ffb@1e is FFB1 67MHz Single buffered 1280x1024@76
For those using the FFB Graphics Accelerator cards, the easiest way to
find out current resolution settings, possible alternative resolutions
for your monitor, and set a new resolution is to use the ffbconfig
utility which configures the FFB Graphics Accelerator and some of the
X11 window system defaults for FFB.
/usr/sbin/ffbconfig -prconf
/usr/sbin/ffbconfig -res \?
/usr/sbin/ffbconfig -res 1152x900x76
The following utility will apparently work on any solaris machine which
any graphic card. Although, as far as I can tell, you still have to
look up in the field engineer's hand book the possible resolutions that
are supported for your configuration.
/usr/openwin/bin/xdpyinfo |grep dimension
To set the resolution, run the following command as root:
# eeprom output-device=screen:r1280x1024x76
then reboot. Alternatively, halt the machine and type
ok setenv output-device screen:r1280x1024x76
ok reset
