I decided to move to the nouveau open driver. Remove nvidia driver: sudo apt-get --purge remove nvidia*
and install the open one: sudo apt-get install xserver-xorg-video-nouveau libdrm-nouveau1a nouveau-firmware It works very well (Ubuntu 12.04 Nvidia GeForce Go 8400M GS). No Xorg crash so far and no shutdown issues. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/940564 Title: [8400m] nvidia-graphics-drivers (295.33-0ubuntu1), is causing failed restarts. shutdowns & only a blackscreen on tty's other than tty7 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/940564/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
