Comment 7 for bug 264535

Hi Jordan,

Like I mentioned, the patch I did was specific to hardware that's a bit different than yours, so won't fix the issue. However, it's likely that a similar patch may be possible that's particular to your hardware. However, to begin with we need to collect some hardware about particulars about your graphics card. I've prepared a debug -ati package that will print out the info I need. Can you please install this, restart X, and then collect and attach your /var/log/Xorg.0.log? It will have lines prepended by 'BWH: ' in them, which is the info I need.

I've built both amd64 and i386 debs, and included -dbg packages for each.

Once we have the data, I can craft a dithering-enablement patch, however my experience with the other dithering patch was that it took a lot of bit fiddling to get the right settings. Do you know how to build .deb packages yourself? If so, I could point you to the flags and how to tweak them, so you can tinker with them directly. If not, I can make some guesses and we can iterate.
