8.10 logs me out unexpectedly

I backed up my xorg.conf with one from before the upgrade, with any luck this should sort it out. In case it's useful to anyone (my laptop is a Samsung Q45):

Do you have compiz or any compositing stuff running ?

It seems there are other cases with intel hardware, maybe it's a more specific issue in your case :

Actually, the problem continued to occur until I started using a more recent kernel, moving to a 2.6.27 one from 2.6.22. I normally tell apt not to update menu.lst when it gets a new kernel because I've had lots of problems with wireless, which is why I was using an older kernel...try booting with differnt kernels if this happend to you.

After today's updates, opening Google Earth or Dreamchess would throw me out to the login screen. I reinstalled the nvidia driver and that seems to have fixed the problem. FWIW, I have been successfully running the manually installed Legacy driver from nvidia website for several weeks now with no problems until today. But everything is good again.
