Public bug reported: After upgrading from ubuntu 13.04 to 13.10 the touchpad on my Acer Aspire 5720 laptop is no longer recognised by the kernel.
Running xinput I get: ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ ImPS/2 Generic Wheel Mouse id=12 [slave pointer (2)] ⎜ ↳ MCE IR Keyboard/Mouse (ene_ir) id=13 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Video Bus id=7 [slave keyboard (3)] ↳ Power Button id=8 [slave keyboard (3)] ↳ Sleep Button id=9 [slave keyboard (3)] ↳ Acer Crystal Eye webcam id=10 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)] ↳ ENE eHome Infrared Remote Receiver id=14 [slave keyboard (3)] System Settings > Mouse & Touchpad only shows settings for mice (no touchpad settings present). Using Google I see various other reports of the same problem on different laptops and the consensus is that it is a problem with the kernel NOT with synaptics. ***The Acer Aspire 5720 has three physical buttons below the touchpad*** - Left, Right, and a middle 4-way button, which has previously always worked for scrolling up/down/left/right. Only up and down works but it only "scrolls" up or down one line at a time (no continuous scrolling by holding the up/down button down). I have managed to get a partial fix by adding "options psmouse proto=imps" to /etc/modprobe.d/options.conf and then running: sudo modprobe -r psmouse sudo modprobe psmouse That gets the physical middle button scrolling up/down working correctly but still no left/right scroll and no way to turn off touchpad tap to click (Grrr! Grrr! and thrice Grrr!)
