Red Hat Bugzilla – Bug 611611
Tapping any key causes kvkbd to print or move too many letters or spaces
Last modified: 2011-02-16 14:20:19 EST
Description of problem:
For example say I want to type kvkbd, it will type kkkk and stop. I do not know why this is happening. Ever since I rebooted after an update it has been doing this.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. type a word
2. prints the first letter of a word too many times
I'm not able to reproduce this bug. kvkbd works properly for me - for each press of keyboard one character appears.
I tried different kernels and that did not help. I reverted to an older version of kcm_touchpad and that did not change anything. I think it either has something to do with synaptics touchpad driver or kde update. I really need kvkbd to work properly because I am disabled and typing is not easy for me.
this only occurs when tapping the toucpad
I can reproduce this too by tapping touchpad. touchpad button clicks are ok.
A good workaround in the meantime would be to switch to using the keyboard plasma applet.
click plasma/cashew in panel -> add widgets, (search for 'keyboard), double click to add
(NOTE: seems the plasmoid doesn't work when placed on the desktop, I'll be filing a bug about that)
Any idea on what is causing the tapping the toucpad issue with kvkbd?
no ideas yet.
OK, found a workaround. In kcm_touchpad, set 'click time' to something much lower, close to the value of single tap timeout.
I found by experiementing with this value, I could get kvkbd to get 1 click for small 'click time', and up to 10-15 for large values.
Not sure what 'click time' is supposed to accomplish here, but we should consider lowing it's default value, provided if doing that has no other ill side effects.
workaround did not work. similar outcome. My values are:
Max Tap move: 59pts
single tap timeout: 307ms
double tap time: 301ms
click time: 308ms
In my testing, I found click time had to be less than double tap. What mine is set to right now that is working is:
max tap move: 59
single tap: 51
double tap: 160
click time: 119

Attached is a working version of kcmtouchpadrc with help from Rex. Tapping for kvkbd is corrected, tapping for moving windows works too.
Let's bounce this over to kcm_touchpad, perhaps we could consider a different set of default values here.
rrix, what'cha think?
kcmtouchpadrc is a real pain. I logged out/in of X and my tapping got screwed up. I have not logged out in several days. Generating a default kcmtouchpadrc does not help. It does not list all the parameters. I'm using:
Everything works except window tapping by moving and highlighting several files/folders by tapping and drag.
Hmm, I never got mail on this, or bugzilla spammed it or something... anyways, let me play with things for a bit on my touchpad and fix up the touchpadrc again...
(and ping me on irc if I bugger out like that agian, Rex, not very responsible of me!)
This is still an issue for F14.
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
I have changed the package in Rawhide to drop the default kcmtouchpadrc entirely. (I'm planning to push that update to F13 and F14 as well.) That way, the defaults from the synaptics driver will be used instead of hardcoded defaults. If those defaults are bad as well, a bug should get filed against xorg-x11-drv-synaptics.
