[solved] Touchpad not responding when using the keyboard

When I try to move the touchpad while pressing one of the keyboard keys, the touchpad doesn't respond. Not all keys though, only the non-modifier keys (letters, numbers, space and maybe others). This issue is on a thinkpad which has a trackpoint. Unlike the touchpad, the trackpoint works as expected.

Here is my xorg config.

Section "InputClass"
        Identifier "libinput touchpad catchall"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
        Option "Tapping" "on"
        Option "TappingDrag" "on"
        Option "NaturalScrolling" "on"
EndSection

Section "InputClass"
    Identifier	"Trackpoint Wheel Emulation"
    Driver "libinput"
    MatchProduct	"TPPS/2 Elan TrackPoint"
    MatchDevicePath	"/dev/input/event*"
    Option		"EmulateWheel"		"true"
    Option		"EmulateWheelButton"	"2"
    Option		"Emulate3Buttons"	"false"
    Option		"XAxisMapping"		"6 7"
    Option		"YAxisMapping"		"4 5"
EndSection

Re: [solved] Touchpad not responding when using the keyboard

man 4 libinput wrote:

      Option "DisableWhileTyping" "bool"
              Indicates if the touchpad should be disabled while typing on the keyboard (this does not apply to mod‐
              ifier keys such as Ctrl or Alt).

This might also be changed in a more fine grained manner by e.g. your desktop environment (I know KDE can set a ms timeout, so potentially also check there)
