I have had this problem since upgrading to 8.04. Latitude D630 64bit realtime kernel (changing to non-realtime kernel doesn't help). Upgrading to 8.10 didn't help. I was using KDE, and during 8.10 I changed to Kubuntu, which didn't help. Now 9.04 inherited the problem as well. I just found someone claimed upgrading BIOS solved it, but upgrading my BIOS to the latest A15 didn't help. Another guy it was fixed in the 180.11 drivers, see http://ubuntuforums.org/showthread.php?t=1084125 But I don't know what I should do with that.
