x11 config file

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).

The open source 'nouveau' driver (in package xorg-x11-drv-nouveau) is the recommended alternative for users of Nvidia graphic chips.  It is used by default in Fedora 11 and later if you remove any customizations that explicitly set the video driver.  The older "nv" driver may be needed in some cases.  It is also available in older Fedora releases.  Install the packages xorg-x11-drv-nouveau or xorg-x11-drv-nv and override the X server's default choice if necessary.  See https://fedoraproject.org/wiki/Features/NouveauAsDefault for more information.

If you used a non-packaged version of the driver from the Nvidia website please clean your system from additional libraries and software it installed. 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 occurring, 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 we do not support the proprietary nvidia driver, users requiring technical support may also find the various X.Org, XFree86, and Red Hat/Fedora mailing lists helpful in finding assistance:

X.Org mailing lists:
	http://www.freedesktop.org/XOrg/XorgMailingLists

XFree86 mailing lists:

Red Hat/Fedora mailing lists:

yes. i'm using the official NVIDIA driver over here.
i'm very sorry to say that, but the nouveau is a joke in terms of graphic performance compared to the nvidia one. i'm doing web development on this machine, and the graphic capabilities i need are pretty high.

thanks for your the help.
if you got any advice about optimizing the performance of the nouveau driver it will be very appreciated. cause the NVIDIA driver causing a lot of problems indeed.

I recommend upgrading to Fedora 13 and ditching the Nvidia binary.  F13 is currently  scheduled for release on 2010-05-18
