Hi, Did you read this section already? http://appdb.winehq.org/objectManager.php?sClass=version&iId=7775 Its possible to run it under Ubuntu but you just should test out a lot of different configuration but maybe this section should help. It would absolutely not work under Ubuntu 10... x64 i can tell you that. I`m a big fan of FSX and im trying to get it work also and i now its possible because a lot of ppl told me they get it to work. Good luck and let us know ok. [/url]
