Eu gosto de usar meu carbono x1 com a tampa fechada e conectado a um monitor externo. O problema é que a tela sensível ao toque se comporta mal, causando estranhos problemas de rastreamento com o mouse USB (o cursor pula).
Eu editei /usr/share/X11/xorg.conf.d/10-evdev.conf como tal:
Section "InputClass"
Identifier "evdev touchscreen catchall"
MatchIsTouchscreen "on"
MatchDevicePath "/dev/input/event*"
Driver "evdev"
Option "Ignore" "on"
EndSection
Isso resolveu meu problema ao trabalhar com o monitor externo, mas quando usei meu laptop mais tarde sem o monitor externo, o trackpad não estava funcionando.
Alguém sabe como desativar a tela sensível ao toque, mas manter o trackpad funcional?
Aqui está todo o conteúdo do arquivo (sem a opção "Ignore"
).

# and other devices that we don't really want to use. The list below
