 Hi everybody,
 
 has anybody managed to get a Fujitsu Siemens 4312 FA LCD display
 or similar configured on debian/unstable (xserver-xfree86  4.2.1-11)? 

I am using an NEC LCD1880SX on an Ultra 60 using a Raritan APSSUN
VGA/PS2 converter.

 I've got the datasheet of that model specifying horiz. freq. 30-81 kHz
 and vertical freq. 56-75 Hz. No success reconfiguring
 xserver-xfree86 with this info. No reactions on the display, black screen. 

I general, from what I have found, LCD panels are extraordinarily picky
about their sync frequency.  They are not true multisync monitors that
can sync at any frequency between the lowest and highest.

For instance, prior to purchasing my LCD1880SX, I had an NEC LCD1850E,
which is almost identical to the 1880SX, but will only do 1280x1024 at
either 60Hz or 75Hz, instead of the 1880SX's spec which says
[EMAIL PROTECTED] or [EMAIL PROTECTED]  I my case, I had the converter box which
could _only_ sync at 76 Hz.  I had to sell my old monitor and get the
new one just to hook up my new Ultra 60.

FWIW, it worked great after I got done.  I realize, of course, after
writing this that it is no help whatever, but I can tell you that when I
tried to send a 76Hz signal to my 75Hz 1850E, I got a black screen, but
the LED on the front did not go orange, it stayed green (which on the
NEC monitors indicates that there is a signal).  Maybe that will help
and at least indicate where the problem might be.
 
 The LCD is ok connected to another machine. I've managed to get
 it up and running on a SuSE linux PC using sax2.
 So that's no hardware problem I tried to copy the modlines calculated
 by sax2 over to the debian/sparc XF86Config-4 file. That didn't help
 neither. 
 
 The display is running fine with 1280x1024-75 on solaris as well using.
 
 Anyone that could help, please?
 
   Micha.

There are two ways of constructing a software design. One way is to make
it so simple that there are obviously no deficiencies. And the other way
is to make it so complicated that there are no obvious deficiencies.

PC monitor on Ultra 60/Elite 3D

[Chad Carr]

Well, I have been lurking on this list a couple of months and received a
lot of good tips about Debian Sparc and love it, and I know that this is
not really the purpose of this list, but I figure that if anyone can
help me those on this list might be able to...

I have an NEC LCD1850E that is supposed to be Sun compatible whatever
that means.  My guess has been that I should be able to use a Raritan
APSSUN to convert the Elite3D's 13W3 connector to the LCD1850E's VGA15.

I have done the following:

1) Set the dip switches on the APSSUN to the position denoting
1280x1024, the native resolution of the LCD1850E,
2) setenv output-device screen:r1280x1024x60 on the boot prom

My PC mouse and keyboard work great though this box.  The screen,
although it is supposed to sync, seems not to.  I have a 15 inch Sun
monitor, and I can tell that it is changing the resolution properly for
both the boot prom screen and X.

Anyone have any hints or any questions that might set me in the right
direction?

Thanks,
