View Full Version : [ubuntu] W500 Tablet - Touchsreen Failure

August 20th, 2011, 03:45 PM
Mouse buttons fail on tablet after 2 or 3 clicks.

I have been attempting to install Ubuntu 10.04, 10.10, 11.04 or Fedora core 16 on an Acer W500 Tablet. Everything works great with a little tweaking, but the mouse fails after two or three clicks. The cursor will continue to move, but the buttons stop functioning. During the installation phase, I have been using a USB keyboard and mouse (IR) which work also, until use the touchscreen. After several different installation here is the configuration that work the best...

Install the ati Nvidia driver: ati-driver-installer-11-7-x86.x86_64
I have used several versions of the driver and it is easy to find on google. The Ubuntu forums documentation will also describe in detail how to make the .bin file into a .deb for installation.

Here is the configuration for the touchscreen.

What can I do to keep the mouse buttons from failing?
