I had some trouble with my Kubuntu 7.04 install and as I still had Suse SLED 10.1 on the drive (unused for several months) booted in and did a huge update.
To my surprise, the *18-1-2 linux client connected without any issue.
Above and beyond that, I can use Amarok and Skype AND SL at the same time without conflicts. Will stay with Suse here now.
Alas it is no mirical as I still wait for voice and video support but that is all that's left to sort out it seems before going beta.
And a "YAY" to the devs while I'm here! For without a linux client I would not be here at all.
