Public bug reported:
I installed the vivd lts upgrade in order to obtain a kernel which
recognised the touchpad on my Toshiba laptop. The kernel now installs
the ALPS driver, but the touchpad is now unusable. Normal light touch
movement is simply not recognised at all. Pressing harder will get the
pointer to move, but it appears to be trying to do things with
rectangles given the screen display, and it's almost impossible to get
it to move into menus. As a consequence I've now started having to use
an external mouse. The sole upside so far is that tap to click is turned
off (which is why I wanted the ALPS driver in the first place),or
perhaps it's turned off touchpad whilst typing. Either way, I no longer
find myself being presented with menus whilst typing, or suddenly
finding the focus has moved. But having to take an external mouse around
with a laptop is a nuisance,especially as the hardware is clearly
working (it works under the kernels from trusty apart from the tapping
nonsense).
