<p>Xorg got really jumpy for me after my upgrade to Ubuntu Edgy. I couldn’t play DVDs fullscreen, and even some Flash animations drove the thing nuts. I poked through alot of launchpad bugs, and finally came up with a solution. I added this to the end of my /etc/X11/xorg.conf file:</p>
<pre><code>Section “Extensions”
Option “Composite” “Disable”
EndSection
</code></pre>
<p>Poof, everything back to pre-Edgy wonderfulness. Obviously, composite’s got a way to go; this laptop has some serious GL hardware, and a little alpha-blending really shouldn’t be an issue.</p>
