I am currently using a Toshiba Satellite P850-138 with Ubuntu 14.04 LTS. I've been running Ubuntu on this laptop for about 3 years without any issues related to the touchpad until now.
I was running Rstudio and attempting to install the package "rgl". The installation failed due to the following error:
checking for X... no
configure: error: X2 not found but required, configure aborted.
ERROR: configuration failed for package 'rgl'
On the basis of this thread: http://ubuntuforums.org/showthread.php?t=787464 I tried to install xserver-xorg-dev, but ran into the following error message:
The following packages have unmet dependencies:
unity-control-center : Depends: libcheese-gtk23 (>= 3.4.0) but it is not going to be installed
Depends: libcheese7 (>= 3.0.1) but it is not going to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
Despite the fact that my current versions of libcheese-gtk23 and libcheese7 are 3.10.2, and so shouldn't cause an issue.
This bug has already been reported (https://bugs.launchpad.net/ubuntu/+source/unity-control-center/+bug/1428972) and the advice in the comments suggested running
sudo apt-get install canonical-certification-client libcheese-gtk23 libcheese7 libclutter-1.0-0 libclutter-gtk-1.0-0 libcogl15 libclutter-gst-2.0-0 gstreamer1.0-clutter
But after running this, I still had the same bug with installing xserver-xorg-dev.
I decided to try to install xserver using the synaptic package manager, which I'm pretty sure is the point where I messed everything up. I chose to install xserver-xorg-dev, and didn't pay attention to the packages that were going to be removed in the process of the installation.
Synaptic installed xserver-xorg-dev, removed other packages and finished. I installed 'rgl' in R with no issue.
When I next restarted the laptop, there was no visible cursor and the touchpad didn't work. This thread (Ubuntu 14.04 no cursor after fresh instalation) prompted me to have a look in System Settings, only for me to find out I didn't have unity-control-center anymore. I reinstalled unity-control-center which fixed the cursor issue, but the touchpad is still not responding.
xinput shows that the touchpad is detected:
⎡ Virtual core pointer id=2 [master pointer (3)]

and cat /proc/bus/input/devices also returns information on the touchpad:

lsmod shows psmouse, which I think is the touchpad, but it isn't being used by anything:

Removing and reattaching the touchpad with
xinput float "SynPS/2 Synaptics TouchPad"
xinput reattach "SynPS/2 Synaptics TouchPad" "Virtual core pointer"
doesn't work, and neither does
sudo modprobe -rv psmouse proto=imps
sudo modprobe -v psmouse proto=imps
I can't find any more threads on this topic online, and I can't think of anything else to try.
