Red Hat Bugzilla – Bug 832321
Keyboard suddenly looses responsivity
Last modified: 2012-06-20 02:01:15 EDT
Description of problem:
Everynow and then (once every few hours or days) the keyboard stops responding in X11. Actually, it does respond, but not "normally". Normally, when a key is pressed it generates an KeyPress event, and if the key is held down after the "repeat delay" (as set by xset) it generates multiple KeyPress events, and when it is released it generates a KeyRelease event. When this bug kicks in, the initial KeyPress event does not take place, but if the key is continously held down, it generates the additional repeat KeyPress events.
Version-Release number of selected component (if applicable):
Fedora 17 with all updates available as of today.
Steps to Reproduce:
Unfortunately I have not yet found a scenario that triggers this bug. But after the onset of the bug the behaviour is visible in xev.
Initial KeyPress events do not occur when pressing a key.
A KeyPress should generate a KeyPress event.
Killing X11 and logging back on solves the problem.
