Re: #261 and #263
Yes, there is "official" work on this issue, see
https://bugzilla.kernel.org/show_bug.cgi?id=14660
Touchpad detection requires a driver that does actually work with the
touchpad. Unfortunately, Alps seems unwilling to release any
documentation on the protocol used by the device. Dell has submitted a
patch that does enable ImPS/2 emulation (wheel mouse). Without it, the
touchpad operates in PS/2 emulation mode (3-button-mouse). Full support
will require reverse engineering of the protocol used by the touchpad
(which seems to require rather complex operations during
initialization), which is attempted by some people on the kernel.org
bugtracker.
Since the Dell patches are NOT included in the maverick (10.10) kernel, for
most of us, the device will run in PS/2 emulation mode by default.
What is supposed to work:
basic clicking: always
scrolling: with Dell patches
deactivate-on-typing, tap-to-click, GNOME mouse control: requires complete
driver or workarounds
Unfortunately, this type of hardware is used in many newer notebooks
(including all new Dell Latitude ("E2") notebooks, as far as I know), so
I hope we shall see full support soon. However, unless Natty has picked
up a driver that fully supports the device (unlikely), many of the
issues are going to persist even with 11.04 (I will try a 11.04 alpha
Live-CD ASAP to provide an answer for Andy (#245)).
