Since yesterday, on every reboot, I have no mouse pointer available - it is possible to get a cross to appear by opening a terminal on screen (by assuming the mouse position as icons expand on mouseover). No border decorations are available on any opened items. This led me to look into the compositor which has been working perfectly for many months. I get this message on screen.
However, switching to any of the alternatives available gets the compositor working again for that session. I installed and tried with metacity too but still get the same problems next reboot. Any ideas on what I need to change or re-install etc?

Processor: Intel® Pentium(R) Dual CPU E2200 @ 2.20GHz × 2
Let me know if you need any other info.
All of the compositors below except for mutter work for the session but all fail on reboot.
