In 14.04 with the 3.13.0-36 kernel, the touchpad and trackpoint on my Lenovo ThinkPad T410s function properly. On upgrade to the 3.13.0-37 kernel, KDE's system admin module says there is no touchpad, though the touchpad and trackpoint function purely as mice. No scrolling withthe touchpad, no possibility of configuring the touch pad to disable tap while typing.
These problems persist with 14.10 and the 3.16-23 kernel. I tried the 3.18.0-031800rc1 kernel. It made the laptop incredibly slow, but did reproduce the problem that kde's admin module does not see the touchpad. (The rc2 kernel available today would not install because of a dependency on a non-existent package (a header package for rc2 with no all, amd64, or i386 suffix).
I have run cat /proc/input/devices for both the 3.18 and 3.13.0-36 kernels. The 13 kernel detects it as "SynPS/2 Synaptics TouchPad", while the 18 kernel detects it as "PS/2 Synaptics TouchPad". However the 13 kernel detects a separate IBM Trackpoint device, which the 18 kernel does not list, even though the track point does function as a mouse with the 18 kernel.
xinput --list with the 13 kernel shows
Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=11 [slave pointer (2)]
⎜ ↳ TPPS/2 IBM TrackPoint id=12 [slave pointer (2)]
with the 16 kernel it shows
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ PS/2 Synaptics TouchPad id=11 [slave pointer (2)]
The most relevant-looking lines of Xorg.0.log are, with the 16 kernel, the single InputClass line
[ 11.702] (**) PS/2 Synaptics TouchPad: Applying InputClass "evdev pointer catchall"
and, with the 13 kernel, the lines
17.820] (**) SynPS/2 Synaptics TouchPad: Applying InputClass "evdev touchpad catchall"
[ 17.820] (**) SynPS/2 Synaptics TouchPad: Applying InputClass "touchpad catchall"
[ 17.820] (**) SynPS/2 Synaptics TouchPad: Applying InputClass "Default clickpad buttons"
[ 17.820] (**) SynPS/2 Synaptics TouchPad: Applying InputClass "Touchpad"
Also, with the 13 kernel,
[ 17.821] (II) Using input driver 'synaptics' for 'SynPS/2 Synaptics TouchPad'
while with the 16 kenrel,
[ 11.703] (II) Using input driver 'evdev' for 'PS/2 Synaptics TouchPad'
I will try to attach the six files.
