Comment 6 for bug 198722

I've the same problem, the mouse cursor crash when I enable compiz. With or without compiz, the scroll of firefox and another app are lagging.

I've enabled the ATI driver from the Hardware restricted driver app.

This is how ubunto recognize my video card:

pfrancav@pfrancav-laptop:~$ lspci | grep ATI
01:00.0 VGA compatible controller: ATI Technologies Inc M56P [Radeon Mobility X1600]

What do you have to do to fix the problem ?
