Comment 3 for bug 252094

Same problem here, with an intel x3100 card (on a Samsung Q45).
Up to 8.04.1 (Kubuntu) I was able to use KDE4 'desktop effects' easily.
Also, sInce upgrading to 8.10 Alpha 3 (from 8.04.1), desktop effects are not working, enabling them results in a mainly black, garbled screen.
