Clean install to Saucy reduces to low-graphics mode and flickering mouse cursor

Question

My laptop used to work perfectly with Ubuntu 13.04 but, after upgrading to 13.10, I am greeted by a flickering underscore in the top left corner of a black screen instead of LigthDM. It quickly moves on to the low graphics mode dialogue and then, after I opt for low graphics mode, starts GDM (which I installed). But the unity desktop I get from this has no mouse cursor (although I can still click on things if I work out where the cursor should be) and is very slow to animate the dash etc. My NVidia drivers are up to date, and the Intel graphics driver seems to be installed as well so can anyone help me resolve this issue and get full hardware-accelerated graphics back?

Answer 1

Have you installed Bumblebee? Usually it solves the nvidia graphics issues in a "smooth way".

And here is something about the mouse cursor
