Default bug report: drivers after 173 kills full-screen Flash performance for the 8200

Been trying the 177.80 (and 82) and then dabbled with the 180.x drivers (but they were severely unstable for me), trying to get decent performance for full-screen flash at sites such as

-http://www.thedailyshow.com/full-episodes/index.jhtml?episodeId=213366
-http://www.hulu.com/hd/45918

Both of these work flawlessly on the same hardware under Windows (an Acer X1200 with 8200 IGP)

Using Ubuntu Intrepid, which installs 177.80 as the recommended driver, performance was single-digit fps at best (usually it just locked up and all but died within 5-10 seconds at full-screen). No measurable improvement seen with 180.

On a suggestion I rolled back to the alternate driver provided by Intrepid, to 173.14.12 and performance is now the full 24(30?) fps or very very close.. magnitudes better than with 177 or 180.

And alas using 173 isn't really a fix for me, b/c I no longer get any audio out HDMI... I seem to need 177.80 for that (and I need 177.82 if I want 5.1 sound, 177.80 doesn't seem to give it).. so maybe that is the clue.. something in the sound processing for 177 broke the video side.

Bug report attached.

EDIT: I have also tried 180.18.. it didn't produce any measurable improvement. Again, 173 is the last driver I find that gives good full-screen flash.. so we know the chip can do it.. just not with the newer drivers. The driver is the only thing I am changing to produce results that show a magnitude of performance loss.

Hi,

I'm having the same problems here. However, I did not even manage to get the 173.14.12 running. Other driver versions work, but the 173. series gives a X segfault:

[ 66.404398] Xorg[6815]: segfault at fffffffc ip b801f6de sp bfe2bdcc error 4 in ld-2.8.90.so[b8012000+1a000]

Any hints on this?

Thanks,
Sebastian

Sorry, I am using Ubuntu 8.10, and the Hardware driver panel gives me 2 choices.. 177 (which is 177.80) and 173 (which is 173.14.12). Those are the "easy" installs for me. When I used 177, I got the bad results.

I also installed 177.82, 180.11, and 180.16 by hand during various other attempts to debug this. But I did not try 173 by hand (never thought going backwards would help, and when I did decide to go backwards I had the easy 173 install via Synaptic)

Hi,

I also installed the ubuntu package (nvidia-glx-173) but only got the mentioned error.

My board is an ABIT AN78GS, CPU is a Athlon X2 5600 in standard configuration (no overclocking or other "tweaks").

With some of the 177.x versions, I got a very poor bitmap performance (not limited to flash video, for example I could see how the background image for the login manager was copied into video memory from top to bottom). Posted here but got no really helpful replies.

So due to the very bad performance and the segfault with 173.x my only option is going back to the VESA driver. I'm about to buy an ATI card and disable the onboard NVIDIA crap.

This is great Linux support.

Sebastian

Kinda wondering how we know if reports make it to the developers or get lost in the noise? (I noticed some threads end up with nvidia folks posting, which would be a big clue )

I don't need a fix today, but would like to know that the devs are aware of the problem and hopefully have it somewhere in the queue for a fix.

thanks,
Mike

EDIT: I didn't realize there was an email addr for submitting bug reports.. I have emailed this thread to that addr (Jan 7)

It's happening to the 8300's also.

Please count me in as one of those wishing for a fix!
