Description Calin Brabandt 2007-03-05 09:39:30 UTC

Description of problem: Under KDE, keyboard state become corrupted.  The
observed behavior is most often similar to a stuck control key, but may
sometimes exhibit the behavior of a stuck alt, "windows start," caps lock,
scroll lock, or shift key.  All keyboard and mouse inputs are corrupted and the
results are often unexpected, irritating, or destructive.  The corrupted state
may usually be cleared by opening a new terminal and repeatedly entering
ctl+enter, windows_key+enter, alt+enter, and/or sh+enter keystrokes.  The
ctl+enter combination will usually clear the error but other combinations are
sometimes necessary.  Keyboard status LEDs have been observed to toggle state
unexpectedly and uncommanded as well.  In extreme cases, it may be necessary to
logoff/logon or reset the computer to resume normal operation.

Version-Release number of selected component (if applicable): FC6 kernel
2.6.19-1.2895.fc6 and KDE of similar "vintage."  The bug has been a problem
since the day FC6 was released.


How reproducible: It may be necessary to install FC5 first, as I've experienced
the problem for months after performing a "yum upgrade" from FC5.  No other
users seem to be experiencing this problem.  I have no method to reliably
reproduce the bug.  A variety of tasks in both terminals and X-windowed aps will
trigger the bug--every 10 minutes or so, on the average, under "power user"
workloads.  I've updated my entire system several times since I originally
upgraded from FC5 and the bug has been persistent.


Steps to Reproduce:
1. Deterministic steps are unknown.  See above.
2.
3.
  
Actual results:
See above.

Expected results:
Normal and predictable keyboard and kb qualifier key (ctl, alt, sh, etc.) behavior.

Additional info:
I have "cloned" this system to several platforms (AMD and Intel based mobos and
both PS-2 and USB kb + mouse).  The problem exists on ALL the systems while KDE
is running.  Gnome and non-X environments both DO NOT exhibit the problem, in my
experience.  I have switched to Gnome to workaround the bug.
