I've just noticed that KDE desktop effects aren't working anymore; I assume this happened after the recent X update. I've tried the alternate Intel drivers in /extra with no luck. I've also tried Alien Bob's KDE 4.4.1 packages... still no luck.
Some info about my graphics card:
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GME Express Integrated Graphics Controller (rev 03)
bash-4.1$ glxinfo | grep rendering
direct rendering: Yes
Attached is a screenshot of the error I get when trying to enable desktop effects. (I've already tried messing with the settings)
