Comment 5 for bug 1028617

I don't know, is this is helpfull, but this bug affects me too. But, i have two diferent adapters, one with earthing ( i hope, this is the correct word, one with 3 "cables" go to wall) and one without ( only 2 cables, i buy it for have to adapters, one for home use, one for traveling ).
With one, that is with earthing, this problem don't appear, but with that one without, problem ocurs. One friend of me told me, that there might be problem with touchpad and not earthing adapter.

But, here is another thing. When i plug in adapter which brings problem ( that without earthing ), problem occurs. But, when i connect my USB hub which has own adapter, shaking is smaller, but when i plug in my HDMI monitor, which has cable with earthing, problem totaly disappeared.

So, i hope, i was helpfull somehow... But if I'm right, i don't know, what can software do for removing this problem.

PS.: sorry, if I broke some rules of this bug reporting, but i never do this before and i just wan't to help.
