How to add touch support for ACER 1820PTZ [MosArt RMTP-MA957]

Asked by axoin

Hello Team,

you've been in the media with your promising project and i hope you can help me.
I have a acer aspire 1820ptz notebook with mosart touchscreen. dmesg states that the device is recognised as MosArt Inc. RMTP-MA957 and mapped to /dev/input/event5. I can see the event information with evtest when i touch on the touchpad.

However, the cursor is always hanging on the upper left side of the screen. It mostly reports Ry and Rz's. I have read about kernel patches etc. but is this still neccessary with your project? (Also ENAC says support is already built in kernel)

How can I help you / or you help me to make the multitouchpad working till Maverick?
tested on daily iso maverick ~18Aug.
