This is something that interests me too. I used to run Seti@hom, but haven't in some time as I normally have Folding@home running to aid with medical science, and also because jobs completed with that add download credit to my Pleasuredome torrent account.

I will definitely be checking out LHC@home when i get some time. Cheers for the info.

@DonAmiga. Post about the problems you are having with Linux/Ubuntu into the Off Topic forums. I've never had any issues getting Ubuntu to install and work, although it can have issues with wireless networks sometimes. Fedora is another I use a lot without issue.
