Nvidia 6200 and ATI RS480/482 chipset incompatibilities

More advanced Nvidia boards (6200 non-TC, 6600, 6800, 7600, ..) don't support TurboCache it is only used on various lowend boards (I think on 7100/7200 cards aswell). As I mentioned I'm using a rd480 with a 6600gt and don't have issues, the same for someone who moved from a 7300GS to a 6600.

I think the issues only appear for cards using TurboCache. I don't know this for sure but based on my result combined with the results of a user who moved to a 6600, it seems to be related.

Thanks for the info. However, I just checked the specs for the 6600 based cards
on the Nvidia website, and it shows that TurboCache is used. So, it appears that
it is some other reason behind the incompatibility. Maybe Lonni could elaborate
on the technical issue (note: I'm not asking for a resolution date) and let us all
know what's the reason behind this incompatibility that occurs only under Linux. Back when I was using the 7300 based card, it worked fine under WindowsXP but it didn't work at all with the Nvidia drivers while running Linux....

The GeForce 6600 has several different models, most of which are *not* Turbocache parts.

Lonni,
Would it be a safe assumption then to ONLY consider
Nvidia cards that do NOT support TurboCache if a user plans to run Linux
on a motherboard that has either an ATI RS480/482 chipset? Since you filed the bug related to this incompatibility, is TurboCache the basic issue or is there
something additional behind the bug?

Development hasn't isolated this bug to Turbocache parts yet, so I can't say for certain.

Hi,

The new BETA driver (1.0-9625) aparently fixes he problem.
I'm running Ubuntu 6.06 with this driver, I tried google earth and it runns smoothly. Besides that it seems to be a lot faster than the old driver and the fonts look better.

You can get the driver here: http://www.nzone.com/object/nzone_do...etadriver.html

Hi,
Forget what i've said, my computer just freezed again with the new drivers.
SHAME ON NVIDIA!!!!! :-@

[Ginyal]

Forget that!
I've just played quake 4 on linux.
It crashed the first time on the level loading screen.
Next 2 times no problem. I finished the single player demo
and played 2 multiplayer games.

--edit, I just ran it again--
Still no problem. Included some screenies to prove.

Also, just fyi. I'm running Ubuntu 6.06.1 with the latest kernel
from the repos (namely 2.6.15-27-k7)

--EDIT: another edit--
It seems I was cheering a bit too early. While nVidia has definitly
improved the stability with release 9625, my doom 3 locked up the 2nd
time I ran it. I was able to play quake 3 and quake 4 without it locking
up though. Also, I experience ALOT of framedrops in quake 3. Not alot
in quake 4 and doom 3, but they are still there regularly. There are also
framedrops in any of the 3d screensavers in Ubuntu. I have included
nvidia-bug-report.log.

Thanks nvidia for improving stability on the drivers, even though the
chipset incompatibility has not entirely been fixed yet. Keep up the good work.

Hello Lonni,

Any news for this bug?

It's really difficult to work thinking that the system is going to freeze in any moment....

Is it any way to disable some acceleration functionalities in the xorg.conf to have more stability? ( I only need tv-out)

p.e. disable render acceleration, or something similar.

Thanks in advance.

[Ginyal]

In any case. This bug has not been fixed yet in 9626.

Hi,

I'm starting to like this situation.
When i'm talking to someone about videocards I tell them "You know, I have a nVidia Special Edition Card!!!"; they say "Really???" and I say "Yes! It's a GeForce 6600 WITHOUT 3D acceleration. It's great, you should buy one."
