Graphics corruption with XF

Graphics corruption with XF

[Josh Huber]

I threw an old Mac64 (VGA compatible controller: ATI Technologies Inc
3D Rage I/II 215GT) into my dual g4 box.  after running X -configure,
I get a semi-working XF86config file.  After tweaking it further, I
still have some problems:

X reports that it could only find 1 MB of video memory, when I'm
pretty sure it's got 4 MB.  This of course severly limits my
depth/resolution, and when paired with the rage 128 I'm currently
using it's a little lacking.. :)

The real problem is that there seem to be some issues with the ati
driver with respect to this card.  The problem definately seem to be
endian related and affect both graphics and text.

Text is corrupted such that the characters are a mirror image of each
other (swapped on the y-axis).  Graphics are fuzzy, and the cursor is
definately corrupted.

Has anyone had any luck with a combination like this?

FYI:
XFree86 Version 4.0.2 / X Window System
(protocol Version 11, revision 0, vendor release 6400)

(II) ATI: ATI driver (version 6.2.3) for chipsets: ati

man XF86Config, look for VideoRam.

Anyone who has must have fixed the ati driver ;)

I suppose it shouldn't be too hard to fix looking at the r128 or glint
drivers.

Oh, BTW - have you tried Ani's rsync tree?

Yes, even with this option I get 1MB of SGRAM used, which severly
limits my choices for resolutions.

heh, if only I had the time to look at this...

I haven't.  I'm in the process of downloading as I type this,
however...so we'll see how that goes.
