Yes. I have removed the proprietary fglrx driver.

I have created "paolo2". A normal boot as this new user brings up a very slow
interface, just as for "paolo".

Just tried that. It also gives me a very slow interface.

One thing which has perhaps helped a little more (but still for only for 
failsafe mode), is creating this link:
    sudo ln -s /usr/lib/dri /usr/X11R6/lib/modules/dri
It is since doing this (I think) that glxinfo now shows:
   direct rendering: Yes

By the way, when I look at the choice of different sessions which Ubuntu gives, 
there are (among others):
- xserver sripts
- Gnome
- failsafe Gnome

Both the first two give me a slow screen. What is the difference between the 
first and the second?
