Description of problem: GIU stops responding to mouse and keyboard input to switch application (ALT-TAB), or to the Windows key. Closing applications by clicking on the X in the top right hand corner also stops working. Also, the scroll down (but not scroll up) on my mouse wheel stopped working. Version-Release number of selected component (if applicable): xorg-x11-drv-synaptics-1.5.0-2.fc16.x86_64 How reproducible: It has happened twice in the last two days. I was just using the system when I became unable to switch between tasks etc. Steps to Reproduce: 1. Don't know 2. 3. Actual results: Can't switch between applications Expected results: Can switch between applications! Additional info: Logging out from X and logging in again clears the fault. Xorg.0.log contained the following: [ 86621.186] [mi] EQ overflowing. The server is probably stuck in an infinite loop.

most likely video driver issue, not synaptics driver. the synaptics driver merely triggers the error. Cause in these cases is usually the video driver (or server) hanging elsewhere. Please attach your full Xorg.log
This message is a reminder that Fedora 16 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 16. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '16'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 16's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 16 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
