Comment 18 for bug 147721

See http://ubuntuforums.org/showthread.php?p=434469

User ubunyou seems to confirm that with kernel 2.6.24-5-generic compiz desktop effects was functioning normally. (I think but I am not completely sure that also with kernel 2.6.24-7-generic compiz was working).

The problem is that I don't remember if under screen and graphics with kernel 2.6.24-7-generic all boxes contained no date, as is the case at the moment, but I am 100% sure that with 2.6.24-5-generic all options and date were available in screen and graphics. Since I adjusted the screen resolution from there.

So the issue probably started for me with kernel 2.6.24-8-generic.
