Brian, Per your comment #231, I removed the shadow branch PPA: ok I installed the version "2:2.12.0+git20100913.08c2caca-0ubuntu0sarvatt~lucid": I guess this is the version from xorg-edgers. Then I shutdown my computer and powered on again. I tested glxinfo | grep "direct rendering": answer is "direct rendering: Yes". I can also run my Celestia program (which uses OpenGL I think), so this seems stable.
So have not the segmentation fault anymore. Thank you for the help. @Anthony: thank you for your info. Maybe you are right. I am not expert enough with this. As I told before the youtube video seems significantly more jerky than before, but I can't tell you for sure if this is since upgrading to 10.04, or upgrading my X server to 1.8.2, sorry for this. Maybe there exist some performance measurement tool that would reflect more objectively this video "fluidity downgrade" ...
