Bug 74638

DOES SHOUTING LIKE THIS MAKE YOU THINK THAT IT WILL GET THE PROBLEM
RESOLVED FASTER?

I don't see your video card listed as being a supported card in the
official XFree86 video hardware support status document for 4.2.0:

http://www.xfree86.org/4.2.0/Status33.html#33

Therefore, it appears that this isn't actually a bug, but rather that
your hardware is just unsupported.  Since I neither have this video
card, nor do I have the technical specifications for it because
Trident refuses to release such information to open source developers,
there's basically nothing I can do about this.

Your best recourse, is to post a POLITE email message to xpert,
requesting driver support for this chip.  Alan Hourihane the Trident
driver maintainer reads that mailing list, and he might be able to
add support for it into some future release of XFree86.

Once it is supported by XFree86, it will be added to a future release
of Red Hat Linux.  In the mean time, you can try using the "vesa" driver.
Keep in mind though, that if the "vesa" driver does not work, it is
generally a bug in the video card's BIOS, and nothing that can be fixed.

THE 'Trident Blade3D' card IS listed as supported at
http://www.xfree86.org/4.2.0/Status33.html#33

and TYPING IN ALL CAPS is not shouting...it's highlighting...

the 'vesa' server doesn't crash on the same test cases that caused the trident
server to crash, but it also doesn't pick a sane modeline for my flatpanel
display  and the interaction between kernel framebuffer and xfree/vesa drivers
pooches the display...  xfree/fbdev doesn't seem to work right either...instead
of noticing that the kernel's using 1024x768, it switches to 800x600.

some of my peripheral difficulties with this configuration were snarks:
it turns out that the 'fbdev' xfree driver is a reasonable but slow workaround.
 the reason it came up 800x600 is that vga=788 was an 800x600 mode.  

i shall report the xfree/trident problem to xpert list, but since this is listed
as supported hardware, with multiple people having difficulties with it, then it
seems fitting that it be tracked here.

1) Typing in all caps *is* shouting.  It's standard convention for electronic
   communication, and well accepted as being shouting by 99% of the community
   for well over 15 or more years.

2) <U>This is highlighting, if bugzilla interprets underline tags properly</U>

3) The Hardware compatibility list is not accurate.  That's not my problem
   because I do not have anything to do with determining what gets listed
   in the Hardware compatibility list.  I do however have everything to
   do with deciding what is and is not supported.  If something is not
   listed explicitly on XFree86.org's status page, then it might or might
   not work, however I consider it unsupported unless it appears there
   explicitly.  If it does appear there, it might or might not be considered
   supported depending on various factors.

It is fine to track your problem here if you like however.

Does disabling acceleration by using:  Option "noaccel" in your config
file (man XF86Config - if unfamiliar with this option) cause the problem
to go away?  If so, we can troubleshoot further to try and find the root
cause.

Closing bug as I'm unable to do anything without receiving a response
to the question I asked in my last comment well over a month and a half
ago.
