Red Hat Bugzilla – Bug 453399
Keyboard delay rate is suddenly increased every once in a while
Last modified: 2015-05-04 21:34:05 EDT
Description of problem:
Without any particular reason, X on F-9 sometimes suddenly changes keyboard
behaviour. Normally, when I press a key, the character pattern is as follows:
(press) x (delay) xxxxxxxxx (release)
After the spurious change, the behaviour changes to this:
(press) (delay) xxxxxxxxxxxx (release)
I never manage to press the key just long enough to emit one character, the
minimum I achieved was two. This leads me to suspicion that two chars are
actually emitted when the repeating pattern occurs.
Control keys (alt, ctrl) behave yet differently. X server takes time to notice
that the key is held, but then refuses to release it. Hence as soon as I press
alt, I can not use backspace, otherwise whole X session goes awol, which is a
typical way such sessions end, because I can never quite keep myself from
pressing backspace instinctively.
Mouse is not affected by this problem.
The keyboard is dell-branded SK-8115.
It has never happened to me on F-8.
Version-Release number of selected component (if applicable):
Not very well. Today it already happened twice, before that the system was on
for a week without a problem.
Steps to Reproduce:
Sorry, no idea.
I'll attach relevant logs in a minute.
I'll try to run xorg.conf-less when it happens next, I don't really need
accented characters for my work.
It seems to me that bug 450249 could be related.

I can confirm that the bug appears also when I run the X server conf-less.
Also the bug has always occurred when I was using the keyboard. I left the
server idle for 9 days (over the holiday), and I normally leave it idle over the
weekend. When I came back, the keyboard has always worked.
I can reproduce this behaviour at will by pressing and holding a left shift key for approximately ten seconds. The same then changes the keyboard back into the "normal" mode. This seems to be some sort of esoteric feature.
can you please cross-check with Bug 445898 and Bug 448604? This sounds like SlowKeys.
445898 seems to be it.
Closing as duplicate then.
