laptop freezing or something like that

[Gatz]

1. I've tried mandriva, ubuntu, fedora, centos, debian and other on a laptop Fujitsu Siemens Pi2550 (now I'm using ubuntu)
the problem is if I'm not moving the mouse for 10 seconds the system is working slow or it stop working. After I move the mouse it resume to the previous process.

for example: If I'm downloading something from internet and I don't move the mouse for 5-10 seconds it stop downloading; after I move the mouse it resume the download.

the same problem I have it when linux is booting; if I don't move the mouse, it stop booting or is booting slowly; when I move the mouse it's booting normally

What's the problem and what I can do?

2. btw my cpu is always on 10-20% on linux. it is normal? I have intel centrino core2duo T8100 2,1G
P.S.: I'm a new on linux

Thanks

This is not normal. If you open a console then type

top

report the process that is eating CPU

this may be related to your other problem.

I see gnome-system-monitor 5-10% and sometimes xorg 3-5%
I'll install ubuntu 9.04 to see more clearly what's the problem (there the cpu is going up to 30%)
btw when I'm using wine cpu0 is 10-20% and cpu1 is 100% (weird)

I'm start thinking the problem is my laptop... maybe isn't made for linux
