CPU loads up to 68-98%

Thank you for taking the time to report this issue and helping to make Ubuntu better. Examining the information you have given us, this does not appear to be a bug report so we are closing it and converting it to a question in the support tracker. We appreciate the difficulties you are facing, but it would make more sense to raise problems you are having in the support tracker at https://answers.launchpad.net/ubuntu if you are uncertain if they are bugs. For help on reporting bugs, see https://help.ubuntu.com/community/ReportingBugs .

Can you provide a print out of top or the resources used under say System Monitor ???

In System Monitor there is nothing that load cpu, just "gnome-system-monitore" (7%). There's also one - "trackerd" (cpu - 0%, nice - 19), but if I kill it, nothing changes. Also I noticed that if I don't touch mouse and touchpad the load of cpu is about 30% and if I move the mouse, cpu load is 60% and higher (till 98%)

I've seen something similar to that when using free graphics drivers on an ATI card--I think the graphics drivers are trying to use the CPU to do what the graphics processor should be doing. If you're using an ATI or NVidia card, check that the proprietary graphics drivers are enabled (if you're OK with that), or try turning desktop effects off.
