You could try reinstalling the kernel as Peter suggested, but I will
be surprised if that is the problem.  However I am often surprised....

What happens if you boot with the latest kernel but then login as a
different user or as Guest?  This will show whether it is the settings
for the user that is at fault or something more fundamental.
