laptop freezing or something like that
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
