+++ This bug was initially created as a clone of Bug #15751 +++

I think I have more problems than the guy of Bug #15751:
I have NVIDIA 7300LE
I have a dual AMD x64
I have a DFP 1680x1050
I use Fedora core 10 with default nouveau.

If I use mplayer full screen it loose frames and after few seconds it stop.
If I use mplayer with a windows size bigger than the native avi dimension (say
1400x900) it freezes also.

I also tested with another monitor size (1400x1050) and mplayer also stop. 

(The problem is that the NVIDIA driver and the akmod-nvidia frezes with my
system and nv cannot use more than one video!)

I attach some file

Can you also provide your Xorg.0.log?

If I understand you correctly the problem is with mplayer and video that is
scaled larger than the native size? Or are most of the applications also
slower? What happens at lower resolutions like 1024x786?

Thank you for the quick answer.

I provided Xorg.0.log now: sorry It's my first time ;-)

Speed: with NVIDIA driver (before it freezes) glxgears give something like 1900
frame/s!
nouveau (and nv) give approx 193 fr/s for the same window dimension.

If I change the resolution to 1024x786 mplayer does not stop (when fullscreen)
but still have some imperfections in the images.

If you tell me how to check video performances in a better way I can try them.
My impression is that it is always slow (even when it creates the desktop).
Anyway, nv is able to run full screen video at the maximum resolution even if
the glxgears performances are comparable with nouveau (direct pixel renering
problems?)

I would like to add anoother thing that does not work:

I cannot switch user: after a few seconds I just get the default request to
enter my password (like after looking the screen) rather than giving me the
possibility to choose a different user name (I cannot use the switch user below
the password text line). 

I use gnome (last release of fedora 10).

1) 3D acceleration is disabled currently, so glxgears will be much slower than
the Nvidia driver. That is expected.

2) Are you using Compiz or some other window manager with 3D effects? If so,
please disable them because they will have the same problems as above. In Gnome
you can usually look in the
'System->Preferences->Appearance->Effects' tab and
change to 'None' to disable Compiz for example.

Otherwise I don't see why it should be really slow, I use a similar card and
have no problems.

Sorry, I'm not using Compiz: it is the first thing I disabled when the
driver
started to give me problems!

Do you use a similar or the SAME card? If it is not the same card (3700LE) it
could be simply a bug that exist only on my card. The NVIDIA driver does not
work on my card but works on my NVIDIA at work (that is not a 3700LE).

Can anyone solve the problem for this card!

Can you use OProfile or Sysprof and get a profile from a couple of minutes of
usage?

I have a similar card, but all Geforce 6 & 7 use the same rendering code.
Maybe
that is not suitable for cards like yours.

Hi Younes,
   Excuse me but I never used oprofile! What exactly I should do: what options
you would like I use and what actions should I do. 

The actions should probably be to start a movie, to resize the smplayer window,
to put it full screen: do you want more? 

How I run oprofile: what setup and format (and how I set them!)?

I will immediately post the zipped profile files.

1) Install the OProfile package for your distro.

2) Run this command: sudo opcontrol --separate=lib --no-vmlinux --start-daemon
&& sudo opcontrol --reset && sudo opcontrol --start

3) Do some stuff that appears slow with nouveau for 2-3 minutes.

4) Run this command: sudo opcontrol --stop && sudo opcontrol --shutdown
&&
opreport -l >nouveau-profile.txt

5) Attach the file "nouveau-profile.txt" to this bug.

Created an attachment (id=24906)
 --> (http://bugs.freedesktop.org/attachment.cgi?id=24906)
produced with Oprofile

Thank you for the instruction: I attach here the nouveau-profile.txt.gz.
This is what I did:
1) I started smplayer (ultra-slow) at the native movie dimension and I enalrged
the window until the movie stopped. The movie stopped also during resize but I
could restart it.
2) Then I just moved a window quick around the desktop (it left a long tail and
it was slow also)
3) Then I tried to switch user but it was not possible and I had to log in
again
4) Finally I take a fast trip in google earth 

Tell me if You need something more.

You are using something that uses a lot of OpenGL rendering, I'm guessing
it's
your desktop. Find a way to disable it and I'm sure the problem will go
away.

Like I said earlier, 3D acceleration is disabled in the driver, so if you
attempt to use a 3D app it will be rendered in software, and be very very slow.

Actually, can you install the debuginfo packages for Xorg and Nouveau and
repeat the process *without* using Google Earth, or any other program that you
know does 3D rendering? We already know why 3D programs are slow, we need to
figure out why the rest of your desktop is slow. Please don't run anything
that
you know uses OpenGL so the profile will be more accurate.

oprofile without opengl

As soon as you sent the first message I realized my ingenuity.
I installed:
xorg-x11-drv-nouveau-debuginfo.x86_64                               
xorg-x11-drv-nv-debuginfo.x86_64                                              
xorg-x11-server-debuginfo.x86_64                                         
xorg-x11-server-utils-debuginfo.x86_64 

And I re-runned oprofile (no opengl): any hint in the attached file?

It appears that this bug report has laid dormant for quite a while. Sorry we
haven't gotten to it. Since we fix bugs all the time, chances are pretty
good
that your issue has been fixed with the latest software. Please give it a shot.
(Linux kernel 3.10.7, xf86-video-nouveau 1.0.9, mesa 9.1.6, or their git
versions.) If upgrading to the latest isn't an option for you, your
distro's
bugzilla is probably the right destination for your bug report.

In an effort to clean up our bug list, we're pre-emptively closing all bugs
that haven't seen updates since 2011. If the original issue remains, please
make sure to provide fresh info, see http://nouveau.freedesktop.org/wiki/Bugs/
for what we need to see, and re-open this one.

Thanks,

The Nouveau Team
