Herd 5 now: same problem on initial install. While researching another problem (#89289), I was prompted to run 'dpkg-reconfigure -phigh xserver-xorg' This re-created the xorg.conf file, and did indeed detect the synaptic touchpad. The vertical scroll area and the double-tap-and-drag selection technique now works!
Here's the area of xorg.conf as built by dpkg-reconfigure: Section "InputDevice" Identifier "Synaptics Touchpad" Driver "synaptics" Option "SendCoreEvents" "true" Option "Device" "/dev/psaux" Option "Protocol" "auto-dev" Option "HorizScrollDelta" "0" EndSection : -- Touchpad not fully functional https://launchpad.net/bugs/88692 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
