fn key to disable touchpad not working
I reported this on https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/1826544 and they suggested posting it here...
On my Asus UX305C when I hit Fn+F9 it's supposed to disable the touchpad. It works properly from the login or when using a LiveUSB. However, on my main account it only shows the graphic to indicate that it's disabling the touchpad and doesn't actually disable it. Subsequent presses show the same graphic with no action.
This started happening after upgrading from Ubuntu 16.04 to 18.04 (I started with a 15.10 install). I suspect some setting is left over that is preventing the button combination from properly working, but going through a diff of gsettings showed
org.gnome.desktop.interface gtk-im-module 'ibus' as the only thing I think would affect it. Other Fn combinations like brightness and volume work fine.
Here's some details:
$ lsb_release -rd Description: Ubuntu 18.04.2 LTS Release: 18.04 $ lsmod | grep asus asus_nb_wmi 28672 0 asus_wmi 28672 1 asus_nb_wmi sparse_keymap 16384 1 asus_wmi wmi 24576 1 asus_wmi video 45056 2 asus_wmi,i915 asus_wireless 16384 0 $ dconf read /org/gnome/desktop/peripherals/touchpad/send-events 'enabled'
The only thing I see in journalctl close to when I press the combination is this (but not on every press):
