Workaroud is here.
1.14.4-5.fc20.x86_64 doesn't affect this problem.
# yum downgrade xorg-x11-server-Xorg xorg-x11-server-common

# rpm -q xorg-x11-server-Xorg xorg-x11-server-common

Same here on a Dell 610 and a few other more recent Dell's.

Another workaround:

  synclient minspeed=10

from a terminal.  This of course does not survive a boot.

'G-spot' on the same machine is not affected.
Comment 2 Matt Smith 2014-06-28 20:08:09 EDT
This affected me after the last update. I was also able to use synclient MinSpeed=10 to get my touchpad to a usable speed. This mght be a problem with the gnome-settings-daemon since that also updated about the same time.

I don't have an additional monitor, I do not understand how this is a duplicate.
Comment 5 Hajime Taira 2014-06-29 20:56:28 EDT
I don't have external monitor too.

Have you tried actually reading the bug this is marked as a duplicate of ?

Note that, as mentioned in that bug, "sudo yum update --enablerepo=updates-testing xorg-x11-*" will fix this.
Comment 7 Matt Smith 2014-06-30 04:13:16 EDT
Yes, I tried reading the bug. I found that it described a similar effect but with a different environment. I also found that it was posted before I started having trouble with my touchpad. I didn't read all of the comments because it does not appear to be the same bug. So I asked the question here.
Comment 8 Hajime Taira 2014-06-30 12:15:40 EDT
I tried to apply following packages from update-testing repo.
It fixed this issue in my environment (Dell Latitude E6230).
