Comment 12 for bug 560433

I've seen the occasional freeze since assembling a Clarkdale system - Core i3-530, Intel DH57JG, 2x2GB G.Skill ECO 1.35 DDR3 memory - and I've noticed that it doesn't seem to apply the visual effects I select, either.

I figured this was a deficiency in the older driver that shipped with 10.4, so I hooked up to the xorg-edgers PPA and ran an update. Problem still existed as of about 20 minutes ago. Haven't yet tried the kernel that Lars just linked, though disabling the effects entirely does seem to prevent it from happening (at least, I've never had it happen with them disabled).
