Description Sean A. Fulop 2018-07-02 07:14:37 UTC

Description of problem:
Touchpad cursor movement lags and freezes; keyboard input freezes at random and then enters numerous repeated characters from the last key pressed.

Version-Release number of selected component (if applicable):
I only selected a component because of the requirement for submitting the bug.  IN fact, there is no specific component to which this is applicable.

How reproducible:
Happens all the time in all software apps.

Steps to Reproduce:
1. Start Fedora
2. Run any app requiring use of the keyboard and touchpad.
3.

Actual results:
Keyboard randomly freezes briefly and enters repeated characters; 
Touchpad randomly freezes motion

Expected results:

I don't know which component this should be either, but it's certainly not gnome-libs, which is part of the ancient Gnome version 1 stack.

Are you sure you don't have something causing heavy CPU load on your computer?

I'm not running anything much, and system monitor doesn't show significant CPU usage at the moment but the problem is still ongoing.  I've run several versions of Fedora on this machine for the past year or so, only Fedora 28 has caused this to happen.  I have never seen this happen on this computer before Fedora 28 upgrade.

Perhaps your issue is similar to Bug #1218402?

Comment 4 Sean A. Fulop 2018-07-10 05:12:39 UTC

It seems as if the main app with these problems is Mozilla Firefox.  Perhaps if they upgrade versions it will eventually help.  Emacs doesn't show the problem hardly at all, nor does the terminal window.

Comment 5 Sean A. Fulop 2018-07-10 05:14:25 UTC

Scratch that, it *does* happen in the terminal window.

Comment 6 Paul Howarth 2018-07-11 14:59:08 UTC

Would you be OK if I marked this as a duplicate of Bug #1218402? You'd get CC-ed on that ticket, which looks very similar and probably has the right component.

Comment 7 Sean A. Fulop 2018-07-12 04:21:26 UTC

Yes that's fine, apart from the fact that they don't mention the typing problems, I do have the similar problems with mouse lags.

After recent updates to Fedora 28 system, the reported problem has seemingly gone away.  I still have no idea what actually was causing the behavior.
