Eu li algumas respostas sobre como ativar o touchpad em outros laptops, mas isso não funciona no meu caso. Eu listei dispositivos no meu laptop e encontrei o touchpad.Então eu tentei ativá-lo.
xinput set-prop "SynPS/2 Synaptics TouchPad" "Device Enabled" 1
No entanto, isso não funciona no meu caso. Eu verifico minhas propriedades com
xinput list-props "SynPS/2 Synaptics TouchPad"
