What graphics chip does it have? If you don't know, please post the output of
'lspci|grep VGA'.
Here's the whole bus, or, at least all of PCI bus that 2.2.18 <vanilla> can
find:

'lspci' and/or LINUX only seems to be seeing PCI bus 0, which everything
except a wide-SCSI card is currently plugged into. The so-called 'IMS'
card (actually an ix3D) iswhat MacOS and LINUX are able to use so far.
For those not listening earlier, i have a PowerMac 9500 with an XLR8 400 MHz
G3, a IXMicro video card and a couple of other things that don't quite work
right yet. I'm using 2.2.18 per Ethan Benson's suggestion, currently on
the 'unstable' branch. I also have a 2.4.0-test4 kernel which works except
for minor mouse confusion. (Hey, i find the 'unstable' branch of Debian far
more reliable than Windows NT 4.0!)
Here's some 'dmesg' extracts which might be helpful:

As you can see, there is now also another display card plugged in, which
MacOS doesn't recognize. (I also have a TGUI9685 card, if that helps might
work.) I don't care much which works with X, but i presume i need it to
be in native (as opposed toMacOS framebuffer) mode, as my eyesight requires
the resolution to be dynamically set in X Windows. I also don't care much
which version of X Windows i run.
I have gotten ix3D get vaguely coherent results now, by setting the
MacOS screen parameters to 1024x768x8. Then the penguin and the text
look clean upon bootup via either BootX or the HFS boot floppy, except
that everything is rotated about 4 character positions to the left [32
bits perhaps??] and characters are not erased properly when the screen
is redrawn. I've not managed to get an X server to work properly in
native mode, only text-only video when the MacOS (and/or its boot ROM?)
has left the card in the right state. It runs happily at a various
fixed resolutions and color depths using the MacOS frame buffer code,
but i can't change that without booting into the MacOS 'Finder'.
Questions:
* What kernel and/or what driver runs the ix3D properly (if any)?
* Can the S3 Trio64+ or TGUI9685 be made to work under X Windows at
least (even if i have to recable for MacOS)?
* Is the ixMicro card (or one of the above substitues) even worth
bothering with? If not, are there modestly priced video cards
which are Mac-compatable and LINUX-friendly? (I don't care how
well they work for games and/or 3D, as i don't play with them.)
Let's try one problem at a time and see if progress can be made that way.
I don't mind kernel or driver hacking to make this thing work, but i want
to do something reasonably expedient about this.
