Several months ago I was looking to get a solution and dig the web for what's happen. The big trouble is Alps did give the source or spec and so nobody can have a reliable driver for that one. https://bugzilla.redhat.com/show_bug.cgi?id=590880#c47 Quotes from Message on the Dell Precision Mailing list "You can patch the kernel alps.c file to stop the kernel from thinking this mystery touchpad is a ps/2 mouse, https://confluence.nau.edu/confluence/display/~cmg238@nau.edu/Recognize+ALPS... However, you still can't access the options for scrolling or multifinger behaviors." There are plenty of bug reports on this, all basically point back to Dell saying we need information about this device. The ALPS rep said you can/should give the information. https://bugzilla.kernel.org/show_bug.cgi?id=14660 https://bugzilla.kernel.org/show_bug.cgi?id=28092 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/550625 https://bugzilla.redhat.com/show_bug.cgi?id=590880 http://bugs.gentoo.org/show_bug.cgi?id=318567 http://fossplanet.com/f10/%5Bbug-773165%5D-%5Bnew%5D-touchpad-recognized-ps-...
