Symptoms
Problem: Screen goes blank when booting a pre-installed OS on Sunblade 100
to multiuser mode with the an SVGA or VGA monitor connected to it.

Reason: The graphics card on this Sunblade 100 is not configured to match
the resolution of the monitor connected to the VGA video connector.

This problem occurs when the system tries to start CDE during the
multiuser boot. Screen goes blank after displaying "starting openwindows".

Resolution
1. Boot the system to single user mode and login as root.
ok boot -s
Press enter when prompted for the password.
(Because no password is set on the preinstalled image)
2. Run the following command to know the supported resolutions for the
graphics card, monitor and the current resolution:
# /usr/sbin/m64config -res '?' | more
The following is the example output of the above command:
Valid values for -res option are:
720x400x70 [2]
720x400x88
640x480x60
640x480x67 [2]

Notes:
[1] monitor does not support this resolution.
[2] card does not support this resolution.
[3] current resolution.
#
3. Set the resolution that is supported by both graphics card and the
monitor.
Note: Do not select a resolution that has a number in the square brackets.
For example:
# /usr/sbin/m64config -res 800x600 now
4. After this, the screen may go blank for a while and come back or
remain blank.
5. Type ctrl+D to take the system to multi-user mode so that it starts the CDE
with the resolution that was set in step 3.
6. Once you get the login screen, login as root and open a terminal window.
7. # /usr/sbin/reboot
Now the system should boot fine to multiuser mode and displays the
CDE login screen.
