Bug Description

Binary package hint: restricted-manager

Install Fiesty Beta 7.04

Use synaptic to install nvidia-glx (nvidia-glx-dev_1.0.9755+2.6.20.4-14.15_i386.deb), then use restricted-manager (restricted-manager_0.18_all.deb) to enable use of nVidia binary driver.

XvMCConfig is left pointing to the xorg XvMC not the nVidia one.

careys@hereford:~$ cat /etc/X11/XvMCConfig
libXvMC.so.1

and it should contain

libXvMCNVIDIA_dynamic.so.1

This is manifest by video playing in totem/vlc/mplayer with audio correctly played but a black screen, and if the window is resized or moved then there are rendering artifacts.

If I change the contents of /etc/X11/XvMCConfig to point to the nVidia library then video plays back correctly.

To further clarify, the problem with video playback appears to be that I ran renouveau --xvmc=1 (http://nouveau.freedesktop.org/wiki/REnouveau) prior to trying to play video back.

See IrcLogs at http://lattice.u-strasbg.fr/irclogs/nouveau-2007-04-08 and http://lattice.u-strasbg.fr/irclogs/nouveau-2007-04-09

If I leave /etc/X11/XvMCConfig pointing to libXvMC.so.1 and restart X then video playback prior to running renouveau --xvmc=1 works correctly

Actually, with
careys@hereford:~$ cat /etc/X11/XvMCConfig
libXvMC.so.1

Are you *sure* that NVIDIA XvMC was working? This can be determined for sure by forcing XvMC output, not the default fall back Xv.

I thought you needed the XvMC from the nvidia binary driver in /etc/X11/XvMCConfig for it to work correctly.

Could you double check?

Thanks for checking again. Right, if you run third-party tools like renouveau, there's nothing we can do about it.

If the file is really wrong in a default installation, this needs to be reassigned to linux-restricted-modules-2.6.22 (nvidia-glx package should handle that itself). I confirm that video playback works out of the box with nividia-glx.

Actually, after checking more with some folks, it does need to modify /etc/X11/XvMCConfig. You can reference this thread for an example that someone needed to: http://ubuntuforums.org/showthread.php?t=644535

After chatting with bryce, he thinks that this fits better in restricted-manager. Particularly because configuration related items are typically handled there.

I think that problem could and should easily be handled by a further
divertion of nvidia-glx and nvidia-glx-new.

Simply divert users of /usr/lib/libXvMC.so.1 to
/usr/lib/libXvMCNVIDIA_dynamic.so.1 and the problem is solved.
No need for error prone modifications of config files.

This should be handled as divertion as done with the other shared libraries. Assigned to right package for this.

Oops, only wanted to add linux-restricted-modules not replace jockey by that.
How does one add a package without replacing hte package in the url?

Thank you for reporting this issue about a driver from the
linux-restricted-modules package. lrm-2.4.24 was shipped with Ubuntu
8.04 which reached end-of-life for desktop support on May 12th, 2011.

For that reason, this bug report is being closed at this time. I'm
marking it wontfix because what you describe is probably a valid issue,
but there are no plans to work on lrm 2.4.24 bugs further.

The issue may be resolved in a newer version. If not, aside from filing
a new bug report, another angle may be to file it directly with the
driver vendor.
