Hi all,
Since upgrading to the 2.6.37.2 from the 2.6.37.1 kernel all my touchscreen messages seem to be relative rather than absolute. Basically touching the screen doesn't move the cursor to where I touch, but touching and dragging my finger moves the mouse, much like a touchpad on a laptop would behave.
I have a feeling this might have something to do with commit c64f6f934c7490faff76faf96217066a1b3570a0 as I have a MosArt touchscreen (can search for commit here http://www.kernel.org/pub/linux/kernel/ … g-2.6.37.2). Does anyone have any idea what could be going wrong, or exactly what the patch linked to does?
Thanks in advance.

Turns out to be a bug with the hid-mosart driver. For anyone else who has the same problem, it should be fixed in 2.6.38 or you can apply the following patch and compile a custom 2.6.37:
