The proprietary 270 driver seems to break composition of 7300 and 7200 series. That's why the screen seems to be freezed but the mouse pointer is still movable and programs are running. It is reported by users of other distributions (Gentoo) and XServer version 1.9 as well:
http://www.nvnews.net/vbulletin/showthread.php?t=160115 I guess we'll have to wait for nVidia to fix it (if they will). That's why we're all warned about proprietary drivers ... While waiting for this I'll try to get the 260 working. Maybe they will, maybe not. The symptoms with composition also explain why some cards are working with 173 (mine as well). I don't have some composite effects like alpha blur. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/728745 Title: [nvidia, 7300, 7400] display freeze when using unity desktop -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
