As I am no Linux expert myself and reading all these problems, I think I'd better ask a few things before installing this driver.
1. Is TwinView fixed? In 6229 and before whatever I did the tv-out always became my primary screen and my tft the secondary. Also the background image was stretched, which if I go by how twinview works on Windows, should not happen.
2. Can I attach my tv to my card while running X and will it be recognized perhaps by pressing a simple 'apply' button? Until now I had to restart X every time before I got any signal on my tv.
Thanks in advance.
