24-bit X server for S3 (esp. Stealth 24)

24-bit X server for S3 (esp. Stealth 24)

Post by David You » Sat, 12 Mar 1994 04:22:39



        I'm producing high-quality ray-traced images with 24-bit color.
As the complexity (number of colors, especially) rises, the more
unattractive they look on an 8-bit display.

        To view these images as they ought to be viewed, and use my
hardware to its full potential, I need a 24-bit X server. I own
an S3 86C805-based Stealth 24 VLB. I understand that support for
this adapter is limited because of Diamond's policies about
releasing programming information only under a nondisclosure
agreement. Even so, there must be a program that will set the
640x480x24-bit color mode for X. I'd like to know about such
a program.

        Perhaps those of us that are unfortunate enough to own
Diamond's products should form a users group. If we work
together, maybe we can change Diamond's policies.

No, that has to be in the X server, and there is currently no support for
XFree for greater than 8 bit colour.

Has nothing to do with that.  There is just no Xserver for 24bit colour,
that's all.  I saw a while ago that someone was working on it, but that
person said it would be done... when it was done.

        Perhaps you would get quicker results looking into developing
vgalib further. It already has "truecolour" support for some chipsets, I
think. Then again, it may be completely different for S3 based cards.
Anyone?

        Hacking the X Server would be no trivial task, well neigh
impossible for the mortals who only use it :) Thanks XFree86 Team!

1. X server cannot show 16-bit or 24-bit color

Hi all,
    I have 2 m/c's. Both have the same problem.
m/c 1 has a matrox G200 card with 8meg ram.Win  NT on this m/c can do
16Million color at 1024x768.X does'nt(XF86 3.3.3.1 BTW).The 2nd m/c has a
Cirrus 5446PCI with 1meg ram.Win95 can do 16-bit color at 800x600.X
does'nt(XF86 3.3.3.1).I've tried startx -bpp16 & startx - --bpp16.But
still the server starts in 8-bit mode.Could domeone please tell me how I
can get X to show High color & true color.

Thanx in advance.
