Ok, Ubuntu Additional Drivers (jockey) utility installed nvidia-173 driver (nvidia-173-updates seems to be still not compatible). You must configure manually the /etc/X11/xorg.config file: go to end anche change the line Driver "Nouveau" to Driver "nvidia"
Reboot and you'll use the new NVidia driver (try glxgears inside a console to watch new performance) jockey will tell you "Current driver is Activated but no in use", but it is a old bug that still returned (see http://ubuntuforums.org/showthread.php?t=1746436) For me the package works fine: I can use again KDE with graphics effects successfully. The only thing: you must modify the package to set automatically the Device key inside /etc/X11/xorg.config file -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1064192 Title: [update request] nvidia-173.14.36 adds support for xserver ABI 13 [quantal] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-173/+bug/1064192/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
