(This is a convertible ultrabook, normally sold with Windows 8.) The touchpad seems to be another ALPS touchpad, not yet recognized by the kernel; I tried the Debian package of 3.12 and linux-next-20131224 compiled from source. Without the proper driver, it is unusuably sensisitive, registering clicks when my hands are well away from the touchpad. The relevant line from dmesg is [ 2.776630] psmouse serio4: alps: Unknown ALPS touchpad: E7=73 03 0a, EC=88 b3 18 Should I try hacking drivers/input/mouse/alps.c to see if one of the existing protocols works? Thanks, Dylan Thurston dpt@bostoncoop.net
