[Jin, Gordon]

I don't think these symptons are normal. But I'm not using Ubuntu, so
I'm CCing intel-gfx and Bryce (from Ubuntu) to see if they see these
issues too.

- Using Ubuntu 8.04 Hardy Heron.

===========================

Now, I'd like to share my experience with this video card.

On Windows xp, I got no problems. Everything works just fine. Games,
movies, everything.

The thing is, I do NOT want to use Windows anymore. And since I tried
Ubuntu I have run into too many problems related to video-stuff.

VIDEO-RELATED ISSUES


I can not run a movie using the apropriate codec. (using gstreamer codec
to watch .avi video format). (1)There is a sound delay. (2)The movie
gets paused unexpectedly. (3)When rewinding/forwarding the movie, the
image gets blured. This happens with compiz-fusion turned off and
Metacity is selected as my default window manager. I don't know whose
fault it is: intel's, OGL's driver (that's why I emailed
michel at tungstengraphics.com) or X's.


GAME-RELATED ISSUES

(4)When exiting a game that was launched on fullscreen mode, my video
resolution is set to 640x480.

(5)Performance is very very poor running games with Compiz-fusion
enabled. I still don't know why this happens.. And it doesn't change
when compiz-fusion is turned off. Is this because of open GL?


(6)As if the video card not working @100% of what I believe it's capable
of wasn't enough, the audio fails to work properly as well (with
Compiz-Fusion enabled).

OTHER ISSUES

Compiz-fusion: (7)when it's enabled, everything else runs too slowly.

(8)I can't even scroll my gmail page up and down... It seems gmail is
too heavy (something really annoying)

I wish you could provide me a definite solution to get this solved, Mr.
Jin.

Like I said, I'm on Ubuntu hardy heron. Please tell me if this video
card's behavior is normal. Or what I should do to get rid of this
poor-performance issue. Seeing this video card not fully working on
Ubuntu is really frustrating.




Thank you,

Rodolfo.
