SUMMARY: Setting SunRay Screen Resolution

Folks,

A few weeks ago I posted to the list, asking if anybody knew a how
to set the screen resolution of a sunray from the command-line. I
did not receive an answer then, but now I got one and some more
interesting tidbits on sunrays. Enjoi. Note that this information
is not official !

NAME
       sunray-faq - Interesting tidbits for SunRay users

OVERVIEW
       SunRay is a graphical terminal from sun. This document
       lists interesting things we found while using these
       beasts.

       This Information refers to SunRay 1.2 and may not be accu
       rate for later or earlier releases.

DESCRIPTION
       Magic Keystrokes


       Ethernet Number
           Press the three gray keys in the top right-hand corner
           of the keyboard, next to the crescent moon to see the
           last few digits of the SunRays Ethernet number.

       Kill XSession
           [Ctrl]+[Alt]+[Backspace] pressed twice kills the cur
           rent XSession.

       Reboot the SunRay
           [Ctrl]+[cresent moon (top right corner)] Power Cycles
           the SunRay.

        Stop Autologout

       When you use a Token card to be able to move your session
       between different SunRays, you may have noticed that your
       session can suddenly disappear while the token is not
       inserted in any SunRay. The reason for this is, that as
       soon as you pull the token from the SunRay utaction starts
       a 900 second wait period and then kills your session. This
       default can be changed to some other value by editing the
       /usr/dt/config/Xsetup file and raise the 900 seconds value
       to some more appropriate value.

       Information about the current SunRay

       With

        xprop -root |grep "_SUN"

       you can get some interesting information ... for example
       the IP number of _your current SunRay in the SUN_SUN
       RAY_CONN_INFO property.

       Setting Screen Resolution for non DDC Displays

       If you attach a non DDC enabled display to a SunRay, it
       assumes that the display wants a resolution of 1024x768.
       You can then use "utsettings" to change to resolution. If
       your screen can not display a resolution of 1024x768 you
       have a problem. Using the following procedure you can
       change the default resolution for a SunRay.

       Edit the /var/dhcp/dhcptab file and add the following sym
       bol:

        DispRes s       Vendor=SUNW.NewT.SUNW,32,NUMBER,4,1

       You can now use "DispRes="X in all the macro definitions
       of your dhcptab file. X is a value between 2 and 15
       depending on the resolution you desire.

         X  Width Height  Hz
        ----------------------
         2   640 x  480 @ 85
         3   800 x  600 @ 85
         4  1024 x  768 @ 60
         5  1024 x  768 @ 75
         6  1152 x  900 @ 66
         7  1152 x  900 @ 76
         8  1280 x 1024 @ 60
         9  1280 x 1024 @ 66
        10  1280 x 1024 @ 75
        11  1280 x 1024 @ 76
        12  1280 x 1024 @ 85
        13  1024 x  768 @ 85
        14   640 x  480 @ 60
        15   800 x  600 @ 60

       If you wanted to change the default for all SunRays to
       1280x1024@75 just add ":DispRes=10:" to the "SunRay-"I
       macro in your /var/dhcp/dhcptab. I is the name of the
       interface where the Sunrays are attached.

       You can also add macros targeted at specific SunRays by
       using their ethernet address as macro name:

        01080020F95B1A  m       :DispRes=10:

       Note the 01 before the actual ethernet address.
