I haven't seen this here in the forum, but please point me to the thread if I missed it.
I can start and play GW2 when I'm using Gnome3 -- and if memory serves, I think using Cinnamon too. But, whenever I try to launch GW2 while I'm using Unity it freezes up the system. This occurs on both of my machines. One is running Ubuntu 12.04, the other 12.10.
Is this happening to anyone else?
