I have always had issues with Compiz + Karmic, so I was not surprised when I ran into problems on Lucid.
I have an EEE pc with Intel GMA950 integrated graphics. Output to the internal screen, compiz works fine. Using xrandr to change my resolution results in compiz crashing. Yet there's no record in any logs of this crash. Theres a bunch of "composite sync not supported" in dmesg, but googling that message didn't lead to anything helpful.
Anyone else having issues with Compiz + Lucid??
