O Ubuntu me desconecta se eu tocar na tela [fechada]

Question

Eu apenas consertei, então funcionou após a suspensão e tentei ativar o multitouch.

Agora, se eu tocar na tela, voltarei ao gerenciador de exibição e terei que fazer o login novamente.

Eu desinstalei TODO o pacote que eu instalei hoje e ainda está fazendo isso. Eu não tenho ideia do porquê, ou como descobrir o porquê.

Edit: Anteriormente, encontrei os registros ...

Ligou um contador de segundos e tocou na tela exatamente às 15:06:00. ##
