** Description changed: On my laptop, every now and then the mouse response will become very sluggish: I move the mouse and only after a certain delay the pointer will move very slowly into the direction I pushed the mouse, and when I stop moving the mouse, the pointer will still keep creeping further into the same direction for about another second. The issue will come and go seemingly at random. For a while the mouse will respond normally; then for no apparent reason I get the aforementioned issue. Usually after a few minutes things return to normal. The machine is a HP EliteBook 6930p running Ubuntu 12.04, fresh install with latest updates (a refurbished laptop that I just picked up). Up to now, I have used Ubuntu 12.04 on a Fujitsu-Siemens Lifebook S7010 for a few months and never had such issues. I have also never experienced this when using a 12.04 live USB with a HP Compaq 6910p (the one I used has an Intel 965 graphics adapter - not the ATI Radeon which is present in some 6910p models and is similar to or even the same as the one in the 6930p). I use(d) Gnome Classic (no effects) on all these machines. Having googled for similar error reports, I have tried out a few things + (see below), to no avail. Both mouse and touchpad are affected by this. When I experience the issue, other graphics operations continue to appear normal, e.g. pressing Alt+F1 will make the Applications menu pop up instantly and response to cursor key navigation is instant. I looked at CPU load in a few instances, but the CPU was mostly idle with both cores somewhere between 15 and 20% load. So the processor is not the bottleneck here. I had the most extreme occurrence of it after I placed the laptop in a docking station (for the first time) with an external monitor attached. I got delays of up to a second, to the point that the mouse became completely unusable. In two instances the mouse went back to normal responsiveness after I closed an open application - Brasero in one case (though no burn or other was in progress when the problem started), display settings in the other case (after I hooked up the external monitor). In other cases the issue just came and went, so I cannot say whether or not certain applications trigger this behavior. I suspect this to be an I/O issue, related to hardware (possibly graphics - I had the most extreme occurrence of it after placing the machine into a docking station with an external monitor attached). CPU load does not seem to be an issue, nor does it seem to be related to a particular hardware port (USB/internal touchpad).
