Hide Forgot
Since updating to Fedora 16 this mornig my keyboard sems to be sufering from excesive debouncing. Any repatd keypreses are lost. This is *not* about autorepeat when I hold akey down; it is that a keypres is discarded by X if the same key has ben previously presed within about half a second. This often sems to hapen evn if another key has ben presed in the interim (as in the word 'even' inthis sentence, and with the space betwen 'in' and 'this' just ther.) All works fine in a VT. xev is not seing the keypres evnts though.

After spending a while hacking the evdev driver and confirming that it *was* posting the events, I've now found that this is a GNOME bug. On upgrading to Fedora 16, its 'Bounce Keys' accessibility option was automatically enabled, and set to about half a second. There's a slider to move the 'acceptance delay' between short and long, but when I slide that down to the 'short' end, then click in the text entry box at the bottom to test the settings, the slider magically jumps back to where it used to be! Thankfully, turning the option off completely does seem to work, and not get reset.
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 It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 Fedora 16 is no longer maintained, which means that it will not receive any further security or bug fix updates.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.
