compiz-0.7.6-2.fc9.x86_64
kmod-nvidia-173.14.09-1.lvn9.x86_64
01:00.0 VGA compatible controller: nVidia Corporation GeForce Go 7900 GS (rev a1)

Compiz seems to be constantly using about 30% of a core.  strace reveals lots of:

 getpid()                                = 30362
 getpid()                                = 30362
 getpid()                                = 30362
 getpid()                                = 30362
...
 sched_yield()                           = 0
 sched_yield()                           = 0

Is it possible for Fedora to fix this bug considering the nvidia binary driver
is being used?

Comment 2 Matěj Cepl 2008-07-22 10:45:40 UTC

Thanks for the report. We are sorry that we cannot help you with your problem,
but we are not able to support binary-only drivers. If you would be able to
reproduce this issue using only open source software, please, reopen this bug
with the additional information, but in meantime I have no choice than to close
this bug as CANTFIX (because we really cannot fix it).

For users who are experiencing problems installing, configuring, or using the
unsupported 3rd party proprietary "nvidia" video driver, Nvidia provides
indirect customer support via an online web based support forum.  Nvidia
monitors these web forums for commonly reported problems and passes them on to
Nvidia engineers for investigation.  Once they've isolated a particular problem,
it is often fixed in a future video driver update.

The NVNews Nvidia Linux driver forum is located at:

    http://www.nvnews.net/vbulletin/forumdisplay.php?s=&forumid=14

Once you have reported this issue in the Nvidia web forums, others who may have
experienced the particular problem may be able to assist.  If there is a real
bug occuring, Nvidia will be able to determine this, and will likely resolve the
issue in a future driver update for the operating system releases that they
officially support.

While Red Hat does not support the proprietary nvidia driver, users requiring
technical support may also find the various X.Org, XFree86, and Red Hat mailing
lists helpful in finding assistance:

X.Org mailing lists:
