Looks like a firmware bug. I see. It's supposed to work out of the box with Linux, and the reviews on Amazon indicate that it really does. So, I guess, either I got a defective product, or maybe Linux has a way to work around the bug. > Is it possible to upgrade the firmware on the touchscreen? The manual doesn't mention firmware upgrades. The display shipped with a lot of accessories, but no software. I could try connecting it to a Windows machine and see what happens.
