Bug Description
The touchpad on the HP tm2 2050 laptop is a synaptic clickpad type. When trying to use the left right and middle 'buttons', only a very narrow strip of the pad along the bottom edge responds correctly - the boundary between the 'pointing' area and the 'buttons' appears to be approximately 700 units too low. Having looked briefly at the code, I have come to the conclusion that either:
a) The value for YMIN_NOMINAL in synaptics.c is too low for this touchpad - i.e. this touchpad does not comply with the Synaptic documentation.
b) There is a low level hardware initialization option for the touchpad controlling the boundary between the two areas that has not been set correctly.
using
option psmouse proto=imps
Forces the touchpad into ps2 mouse mode which removes this problem, but then prevents the touchpad from being further recognised as a touchpad and configured in any way, e.g. to turn off tap to click.

Hi Stephen,
If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https:/ /wiki.ubuntu. com/KernelMainl ineBuilds . Once you've tested the upstream kernel, please remove the 'needs- upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs- upstream- testing' text. Please let us know your results.
Thanks in advance.
