Thanks Akemi and Earl,

This kind of support is a good reason to stay with SL - I will try these two suggested solutions.

Cheers, Bill

Thanks, Earl, for posting this. In fact, *I* should have mentioned
bumblebee. :)

ELRepo's bumblebee and related packages are still in the testing repo.
It is a report like yours that makes it possible to push them to the
main repo. There is a minor typo in the current version of bumblebee
(the name of initscript is missing an 'b' like bumlebee). I will
release the fixed version to the elrepo-testing repo shortly.
