Also happens for me, Dell D630 laptop (64 bit) with Intel GMA 965. I just upgraded from Kubuntu Hardy to Intrepid so I've no idea if this is KDE4 related.

It looks like DPMS is kicking in briefly. The laptop's screen stays on while this happens.

I made it stable by using xrandr to a lower resolution and then xrandr back to the native VGA resolution (1920x1200 in my case).
