Description Richard Myers 2019-04-01 20:42:38 UTC
Description of problem:
Touchpad, Disable While Typing doesn't work consistently.  It seems to take multiple key presses, fairly rapidly to trigger the feature.  This is on a Dell XPS15, 9550, XCFE4, Fedora 29 (w/all updates), kernel 5.0.4.  For some reason, the kernel finds 2 touchpad devices, which are shown in the XFCE Mouse and Touchpad Configuration.

I use the i2c-DLL06E4:01 device, as the SynPS/2 Synaptics TouchPad doesn't seem to work.  Not sure if this has any relevance or not.  Enabling both devices in the XFCE Mouse and Touchpad GUI does not change the issue.

How reproducible:

Always, but strangely intermittent.  During a test (one hand typing, other hand messing with the touchpad), it will sometimes start working, and other times it continues to work while I'm typing.  The frequency at which I type seems to affect whether it works or not (>1/sec makes it work better).

Steps to Reproduce:
1. Open gnome-tweaks GUI
2. Keyboard & Mouse section
3. Enable: Touchpad: Disable While Typing 
4. Open an application or terminal that accepts keyboard input.
5. Type and use the touchpad at the same time. Check to see if the touchpad consistently freezes while typing, and for a constent period afterwards.  

Actual results:

Very inconsistent operation.  I am forced to disable the touchpad, as the my palm brushes it while typing, which changes the focus to somewhere else on my desktop. Very frustrating.

Expected results:

Touchpad is disabled for a some period (preferably configurable!!!) during and after key presses.

Additional info:

Please add back (sometime in the past, this was an option in XFCE, I believe, maybe in gnome 2?) or add in the option to enter a number of seconds the touchpad is disabled after a keypress.
