Screenshot showing the bug

In my Acer TravelMate 7720G and the graphics card: ATI Mobility Radeon HD 2400
XT HyperMemory, after updating Xorg server, Xorg driver and related packages
which Ubuntu 11.04 provides, my desktop is unusable now:

It appears black and white colours - I've been able to record a screenshot
using keys, see it in the attached file.

Now the desktop works correctly only when I use the "booting in safe mode"
option.



I've selected the Driver/radeon component but I don't know exactly the
component I have to choose - it forces me to choose one
