Comment 1 Matěj Cepl 2009-02-25 10:37:55 EST
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:


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:

hmm, this problem seems to be not related to Nvidia binary driver.

$ cat /var/log/Xorg.0.log | grep Misc

$ cat /var/log/Xorg.4.log.old | grep Misc (X.Org X Server 1.5.3 log)

gnome-screensaver needs to XFree86-Misc, maybe.

checking for XF86MiscSetGrabKeysState in -lXxf86misc... yes
