Logging into Ubuntu (i.e., not "Ubuntu on Xorg"), the "Disable While
Typing" Touchpad setting in gnome-tweak-tool now appears to work.
Furthermore, tapping to click does _not_ work, i.e., the behavior I want
is present by default as far as I can tell. In fact, I can't figure out
any way to cause tapping the touchpad to generate a click. So either the
behavior has changed in an update since I reported this bug, or I was
using Xorg but thought I was using Wayland.
Logging into Ubuntu on Xorg, without anything special in any of my X
server config files, the "Disable While Typing" setting in gnome-tweak-
tool doesn't do anything, and tap to click is enabled and there's no way
I can find to disable it. So that appears to be a bug in GNOME, not a
bug in libinput. There should be a way to disable tap to click, and the
"Disable While Typing" setting should be obeyed. If it's not, then I
believe that means GNOME isn't populating that setting through to the X
server the way it needs to be, which doesn't sound like a libinput bug.
Logging into Ubuntu on Xorg, these lines added to the "libinput touchpad
catchall" section of /usr/share/X11/xorg.conf.d/40-libinput.conf appear
to have no effect, even though Xorg.0.log confirms that section is being
applied:
Option "Tapping" "false"
Option "DisableWhileTyping" "true"
Option "PalmDetection" "true"
Perhaps this is a libinput bug, or perhaps the synaptics sections that
are being applied to the device after the libinput sections are
overriding the libinput settings?
Again logging into Ubuntu on Xorg, if I add this to my X config then tap
to click is gone and it seems like there is _some_ protection against
brushing against the trackpad, although there still isn't full disable
by typing:
Section "InputClass"
Identifier "disable touchpad tap to click, enable palm detection"
Driver "synaptics"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event*"
Option "MaxTapTime" "0"
Option "PalmDetect" "on"
EndSection
So, the potential issues that _I_ see here are that the Disable While
Typing setting does not work in "Ubuntu on Xorg", and that the libinput
options I'm configuring into my X server don't appear to take effect.
Should I indeed open a libinput bug about that, or re-open the bug I
opened and closed but clarify in the re-opened bug that it only applies
to Xorg, not to Wayland?
