Comment 60 for bug 557266

@Gary,

If you're already using packages from the xorg-edgers/radeon PPA, then the only thing left to do is install a mainline kernel, as the kernel-side fixes to this issue have not yet been backported to the normal kernel shipping with Ubuntu Maverick. Have a look at this page:

    https://wiki.ubuntu.com/Kernel/MainlineBuilds

Kernel version 2.6.37 was released recently, so that's the one you'll likely want to use:

    http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.37-natty/

(it says "natty," but it will work fine on Maverick. This is what I'm running myself.)
