Config for a Diamond A50

I'm using X 3.3.5 and I haven't been able to find a good config for my Diamond A50.  I would really apreciate some help.
Currently I'm using the following Options:
"no_bitblt", "no_imageblt" and "sw_cursor".
1 Solution

Use the xf86configuration tool to configure the SVGA server for your graphic card. After completing the configuration, edit the file /etc/XF86Config as described below. The example shown below is for a Diamond SpeedStar A50. Find the Device section of the file -- it looks something like this:

Section "Device"
   Identifier      "Diamond SpeedStar A50"
   VendorName      "Diamond"
   BoardName       "SpeedStar A50"

Modify the section by adding the "option" lines as shown below:
Section "Device"
   Identifier      "Diamond SpeedStar A50"
   VendorName      "Diamond"
   BoardName       "SpeedStar A50"
   Option          "sw_cursor"
   Option          "no_accel"
   Option          "no_linear"

You have a working X server, but it produces poor results. You should first verify that you have a cuurrent version of your X server. You can check the release date of your X server with the following command:
       /usr/X11/bin/X -showconfig

Either the second or third line of ouput will say somehting like:
Release Date: January 4 1999

An alternative would be the command:
       /usr/X11/bin/XF86_SVGA -showconfig
       /usr/X11/bin/X -version  (undocumented)

If the X server has a pre November 1998 release date, then you should update your server. You need the SVGA Server for your chipset. Instructions on how to update your X server are given in this SDB acticle:
      Update to XFree86-

2. Solution:
As a result of the work of one of our customers, H. Shultz, it is possible to obtain 24 bpp on some boards:
Insert the following options into the "Device" section of the
/etc/XF86Config file.  This should be added to the existing information in
that section.

Option            "no_accel"
Option            "no_imageblt"
Option            "sw_cursor"
dacspeed      135
Option            "fast_vram"
Option            "no_bitblt"
VideoRam      8192

with these options it is possible to use 24 bbs.  
I have been using these configuration options for X on my computer about a month, with
relative sucess.

If you are having problems with this solution (unreproducible freezing, poor icture quality, flickering etc.), try the first solution. Unfortunately we cannot take any responsibility for damage to your system from these recommendataions ;-(

I guess it would help to know what type of monitor I'm using, since it has programable clocks.  I'm using the Diamond A50 with a ViewSonic 17GS and they are not quite working so well.  Anybody have a good config?
