Quando atualizei do SUSE para o Ubuntu 14.04 LTS, o monitor com tela sensível ao toque está detectando como TOUCHPAD em vez de TOUCHSCREEN . Está usando o ELO drivers para a funcionalidade da tela sensível ao toque.

Depurei este problema, no Xorg Log o tipo é mostrado como "TOUCH PAD" em vez de "TOUCH SCREEN" .

Se você instalar o pacote xinput ( apt-get install xinput ), poderá forçar o evdev a ver o dispositivo como uma tela sensível ao toque pelo comando 

xinput set-mode $ID ABSOLUTE

onde $ID é o id do dispositivo conforme retornado pelo comando 

xinput -list

Esta operação precisa ser feita a cada inicialização e o ID pode mudar em função de outros dispositivos USB, então será melhor fazer isso em um script chamado startx , algo assim: 

#!/bin/bash

export DISPLAY=:0.0
ID='xinput --list | grep "Elo TouchSystems" | sed -e 's/.*id=\([0-9]*\).*//''
xinput set-mode $ID ABSOLUTE

Isso funciona bem com o meu monitor touchscreen (Elo TouchSystems CarrollTouch 4500U) e Debian 8 (Jessie) e talvez funcione corretamente com o Ubuntu também.

O brilho máximo da tela é muito baixo no Thinkpad X300 Ubuntu 16.04 Virtualbox “o sistema não está atualmente configurado para construir módulos do kernel”
