Comment 9 for bug 951673

Firefox has been crashing on me since this update. (I found http://askubuntu.com/questions/100730/how-to-upgrade-to-glx-1-3-on-ubuntu-10-04 and that feels like my problem.) So I'm going to try upgrading xserver-xorg-core to the bleeding edge. If this fixes my problem, (because Xorg is no longer eating into CPU leaving space for actual programs) then I'll report back, otherwise my system is still running slower than normal.
