16 My apologies for not making this more clear. The system load spike begins
17 with the click and it hovers at or near 100% until the new task (opening a
18 program, displaying a menu, etc) has completed. Even moving a window causes
19 this to happen and the load only jumps on one processor, the other is idle
20 or nearly so. When the nvidia driver is working correctly (assuming the
21 driver is to blame) the load seems to be balanced evenly across both
22 processors.

30 top is telling me that X is the guilty party. I can renice X to a lower
31 priority and get some responsiveness back but again, there are times when
32 everything performs as expected. The problem is intermittant although it
33 happens more often than not.
