There is a graphics gui by intel for download.
sudo apt-get install intel-linux-graphics-installer
However, it is for the 32bit system but if you install on a 64, your touchpad mouse will become unresponsive.
You can then do
sudo add-apt-repository ppa:xorg-edgers/ppa
sudo apt-get update
sudo apt-get upgrade
This fixed the xserver crashes and the mouse wasn't disabled after every reboot. If your mouse is disabled, do
sudo modprobe -r psmouse
sudo modprobe psmouse proto=imps
But after re-downloading from the ppa, the issue resolved with the touchpad.
Actually the correct way is to first fix the broken packages, so that you can remove it properly, before you install the new package.
sudo apt-get install -f
once it has installed all the missing dependencies, then run:
sudo apt-get dist-upgrade
when it finishes, at this point you have two choices, manually remove the package you are having trouble with, or doing the full release upgrade, which is the recommended method.
so you can either go:
sudo apt-get remove xserver-xorg-lts-saucy
sudo apt-get install xserver-xorg-lts-trusty
or you can do:
sudo do-release-upgrade
In the worst case scenario, if you already did upgrade to 14.04, but the xserver are still stuck on the old release for whatever reason, you can do this crazy move to remove all xserver files, so that you can re-install from the repositories.
sudo apt-get remove xserver*
doing that will also remove your Unity or Gnome, or whatever desktop environment you have installed, so you'll have to reinstall your choice of desktop environment, and that will automatically get you the missing xserver packages.
if you like the unity desktop do:
sudo apt-get install ubuntu-desktop
or if you prefer the gnome desktop do:
sudo apt-get install ubuntu-gnome-deskop

If your guest account is not affected this could be a user-specific setting that is causing the problem. Try deleting
~/.config/monitors.xml
