I have three problems here.
After I started the app and did the settings, the working area on my Android device is always very small. I looked in the code and found that it’s initialised to 128x128. I modified it to the correct resolution of my tablet and this problem is solved.
While I can move the cursor around by touching the tablet, it behaves like I’m moving a mouse with its left button clicked. When I move the cursor over some text, they’re selected. Even if I touch carefully, it’s the same case.
After I’ve done the settings with GIMP, I still cannot draw with the tablet. I can move the cursor around but cannot draw anything. It’s like the left button of the mouse is broken.
Environment: xorg-server 1.13.0, Linux 3.2.0-32-generic x86_64 Ubuntu, Linux Mint nadia (Ubuntu quantal).
Tablet: Acer Iconiatab A500, Android 4.0.3, Linux 18.104.22.168+
