At least in this Im not the only one having problems. Ive seen a lot of
posts in various ubuntu groups with the same issue - update yesterday on
10.04 and 10.10 system and screen saver no longer works.

This might be a alpha but I have to say - except for my original
problems which had nothing to do with any of the versions, I have had
less problems with 11.04 than anything past 8.04. Yea, a stretch but -
its been nice.
