Refresh is: vfreq:  0000004c = 76Hz and need to be set to 66Hz.
I think I can manage that.

Thanks,
Frits.

Frits,

/dev/fb0 (and /dev/fb1 on dual headed boxes) are linked to the video
drivers, 
so ls -l /dev/fb0 should show:
 lrwxrwxrwx   1 root root 10 Jan 13 08:57 /dev/fb0 -> 
fbs/cgsix0                                            

B boxes normally had cgsix frame buffer (GX or Turbo GX video cards),
although 
I commonly see CGthree cards in B boxes (probably migrated from A boxes).

You can also browse the messages files:
dmesg | egrep '(cgthree|cgsix)' to see your video cards.

You're probably running both cards at 1152x900x76.  To see the refresh rate
dig 
into the output of:
# prtconf -vp
or, download the fbinfo script from Sun at:
http://www.sunhelp.org/faq/progs/fbinfo

In most cases you shouldn't have to set the video resolution.  Default 
resolution is set by returned sense code according to the following:
Code    TGXplus(1)      TGX(2)          GXplus          GX (LSC chip)
-------------------------------------------------------------------
7       1152x900x66     1152x900x66     1152x900x66     1152x900x66     
6       1152x900x76     1152x900x76     1152x900x76     1152x900x76     
5       1024x768x60     1024x768x60     1152x900x66     1152x900x66
4       1152x900x76     1152x900x76     1280x1024x67    1152x900x76     
3       1152x900x66     1152x900x66     1152x900x66     1152x900x66     
2       1280x1024x76    1152x900x66     mutant(3)       mutant(3)
1       1600x1280x76    1152x900x66     mutant(4)       mutant(4)
0       1024x768x77     1024x768x77     1152x900x66     1152x900x66



Setting B box video card resolutions is not trivial.  D and E boxes have 
command line tools (m64config, ffbconfig and GFXconfig), but B boxes need 
changes made to the eeprom.  To reset the resolution on the primary video
card 
you can do:
# eeprom output-device=screen:r1152x900x66
and reboot, or at the Forth toolkit ok> prompt:
ok> setenv output-device screen:r1152x900x66
and boot.

To set the second video card resolution, see the Sun Frame Buffer FAQ 
description at:
http://www.sunhelp.org/faq/FrameBuffer.html#2b
