I have both of these cards: #9 771 4m vram and the very similar DS64 video 4m
vram.
I bought the official redhat 303 2-disk set, with metro-X.
I'm getting really tired of the 'dashed line' bug in this series of video
cards; I wanted to see if the MetroX has a better work-around than XFree86
does. Nope.
In fact, I get almost NO success even getting the screen to 'turn on' with
metro X.
What's interesting, is that if I choose #9/771 (ie, I lie to the configX
program, since I really have a DS64 at home) I get _some_ video. With the
real DS64 menu setting, I get NOTHING! Why?? [metroX: do you have any
updates for us REDHAT users?]
Could that be due to the "RAMDAC of the Month" game Diamond plays?
Or maybe configX decides that "DS64" means one of the several other
Stealth64 models, at least some of which don't even use an S3
chipset, let alone the 968.
When I tried MetroX at work (with my #9 card), it works somewhat. However,
the * horizontal (vertical, depending on how you describe it) dashed line
bug is still there.
(FWIW, the latest demo of AccelX ALSO has this bug!!)
Note: all the s3 968 cards I use have the IBM ramdac in them. I took folks'
advice and avoided the TI chip. I tried one once, and it also had the bug, but
also seemed a bit slower. Maybe it was just how I felt that day - don't know
;-)
Simple question:
Why is this chipset so badly designed? Or, why doesn't this company release
info on how to work-around this bug effectively? I really can't say I'm all
that happy with s3, at this point. Or #9 or Diamond ;-(
(For those who don't know this bug, it appears when you enable the virtual
root window and start moving windows, opaquely, left-to-right. I used to get
around it by setting my physical screen == virtual screen. However, since I
recently got a 1600x1280 screen, I want to ctrl-alt-<+> to move between 1024,
1280 and 1600 (horiz). I see no way to disable the dumb virtual screen when
you need to run at 1600 _physical_).
Its ok for a free X-server to have these bugs (IMHO), but for BOTH commercial
servers to ALSO have it is intolerable. Who would spend $100 or $50 for an
X-server only to find that THEY didn't work-around the bug, either!!
If there is, in fact, such a bug, at least SOMEONE knows how to work
around it. My STB Velocity 64, with the S3 968 and the IBM RGB524
RAMDAC has never produced such symptoms (nor any other undesirable
ones) in XFree86 3.1.2. That's with 16bpp -- I almost never use any
other depth so I haven't tried them to see if there is a problem
there. Sorry you had such crappy luck with the two brands you have.
