I am using an Acer Iconia W500 tablet PC with a fresh install of Ubuntu and the touch screen stops responding shortly after login.
It works fine before this time and does not seem to be related to any apps because if I leave it idle for a few minutes it still does it. I originally thought it was a bad touch screen driver so I plugged in a USB mouse to diagnose the issue.
The USB mouse moved the cursor but would not allow me to click on anything. The touch screen also moved the cursor correctly but wouldn't click. Also various 'mouse over' effects don't work either. I plugged in a keyboard to see if that works and it did. It responded to the keyboard but not mouse clicks. All settings are default. Any ideas?
