I have just upgraded from 11.10 to 12.04.1, following the upgrade I can log on but following that no top or side tool bars are visible.
I did a clean install (with Format) but the result was the same. I can right click on the desktop and look at settings, I can also shell out to a terminal.
Other posts I have read suggest this may be a graphics driver issue ( card is Nvidia 9600GT). Tried updating the driver but with negative result.
There are 3 other operating systems on this PC all of which function fine. My previous incarnation of Ubuntu also ran without apparent problems.
Can anyone shed anly light on this problem.
12.04 runs ok directly from live cd.
