Yes, that's true. I am also now using version 8.40.4. So try to install latest drivers available from ATI. A good step-by-step description how to do so is located at ubuntu.com (direct link: http://tinyurl.com/39kpsy). I also had the same problems with my PCI-e X600: Starting eg. OO just showed me the splash screen for half a second and then it just closed /wo any error-msg. Now with my 'selfmade' fglrx drivers everything runs just fine. It's really worth taking some minutes to compile your own *.deb's ;)
