Description of problem: X frequently (but at irregular intervals) grabs 80 percent or more of the cpu time for short periods (~1 second). The interval varies from a few seconds to 45 seconds (very approximately). The spike in cpu usage is so severe that keystrokes (e.g., being entered into an editor) are lost. Version-Release number of selected component (if applicable): Using gnome WITHOUT compiz enabled (i.e., so that metacity is the window manager). I've confirmed the problem with nothing but xterm running in a gnome login session. I'm using the kmod-nvidia driver. How reproducible: There are times when it doesn't happen at all. But usually it is producible. Steps to Reproduce: 1.Log in 2.run top -b -d 0.2 >top.log for at least 45 seconds 3. Search top.log for "X" occupying CPU time of at least 80 percent.

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: http://www.freedesktop.org/XOrg/XorgMailingLists XFree86 mailing lists: http://www.xfree86.org/sos/lists.html Red Hat mailing lists: https://listman.redhat.com/mailman/listinfo
