I seem to have the same problem on a Dell Latitude e7440 since the update to 14.10. After some time the touchpad and the trackpoint stop working, i.e., the mouse cursor is frozen and there's no reaction to clicks. Similar to the reporter Xorg.0.log contains the following error:
[...] (EE) AlpsPS/2 ALPS GlidePoint: Read error 19 [ 11.296] (II) config/udev: removing device AlpsPS/2 ALPS GlidePoint [ 11.320] (II) UnloadModule: "synaptics" [...] I noticed, that the touchpad is functional again after waking up from suspend (e.g. by closing the lid). -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-input-synaptics in Ubuntu. https://bugs.launchpad.net/bugs/1382865 Title: Dell Latitude E6330 Touchpad stops working Status in “xserver-xorg-input-synaptics” package in Ubuntu: Confirmed Bug description: After login, at some point the touchpad stops working.
