Old thread yet I had this problem recently, after installing Ubuntu on a mostly unsupported laptop I had problems with sound. I uninstalled PulseAudio and Unity was affected. First update and upgrade your system and run auto-remove.

$> sudo apt-get update

$> sudo apt-get upgrade-distro

$> sudo apt-get upgrade

$> sudo apt-get auto-remove

See if that fixes it for you - if not, then I recommend you check Unity and try installing

LXDE to make sure X-Windows isn't the issue.

$> sudo apt-get install unity

$> sudo apt-get install lxde

At this point it should be working, try

$> startx

If it is, yet you still get the "low-graphics mode" message on reboot then install a new greeter for LightDM:

$> sudo apt-get install lightdm-gtk-greeter

Now it should be fixed.
