Bug#576211: xserver-xorg-input-synaptics: ValuatorAxis limits are set from device limits
Package: xserver-xorg-input-synaptics
Version: 1.2.1-1
Severity: important
Tags: upstream patch
Hello,
the synaptics driver set the ValuatorAxis limits to the device limits (like an
absolute axis device - synaptics driver sends relative events) and the X
pointer position can obtain only discrete values. The cursor moves by stairs.
Example:
X-resolution: 1920
Touchpad: x-axis range 32 - 544
Only every 1920 / (544 - 32) = 3.75 column can be hit
Next simple patch disables setup of the ValuatorAxis limits and after applying
the patch the cursor moves smoothly with a pixel precision.
Regards,
Tibor Zenis
